Description

DOMAINE TECHNIQUE DE L'INVENTIONTECHNICAL FIELD OF THE INVENTION

La présente invention se rapporte au domaine de la sécurisation de documents, telle que des passeports, sur lesquels sont inscrites des données de personnalisation.The present invention relates to the field of securing documents, such as passports, on which are recorded personalization data.

Elle se rapporte plus particulièrement à un document à sécuriser comprenant un support de données et un composant optique de sécurité, le support comprenant deux faces, le composant optique comprenant des moyens aptes à générer des effets optiques et des moyens adhésifs adhérant à une face du support, des données de personnalisation étant inscrites sur le document.It relates more particularly to a document to be secured comprising a data carrier and an optical security component, the support comprising two faces, the optical component comprising means capable of generating optical effects and adhesive means adhering to a surface of the support. , personalization data being written on the document.

Elle se rapporte également à un procédé pour sécuriser un document comprenant un support de données comprenant deux faces, le procédé comprenant une étape d'inscription de données de personnalisation sur le document et une étape de transfert d'un composant optique de sécurité sur une face du support, le composant de sécurité comprenant des moyens aptes à générer des effets optiques et des moyens adhésifs adhérant à la première face du support.It also relates to a method for securing a document comprising a two-sided data carrier, the method comprising a personalization data enrollment step on the document and a step of transferring a security optical component to a face of the support, the security component comprising means capable of generating optical effects and adhesive means adhering to the first face of the support.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Les documents d'identité tels que les passeports sont la cible d'un grand nombre de tentatives de contrefaçon visant à falsifier les données de personnalisation pour les remplacer et ainsi détourner l'usage du passeport, ce qui est notamment le cas avec des passeports volés.Identity documents such as passports are the target of a large number of counterfeit attempts to falsify the personalization data to replace them and thus divert the use of the passport, which is particularly the case with stolen passports. .

Pour authentifier et protéger ces données personnalisées, il est connu de recouvrir la page imprimée - ou support de données - d'un ensemble de couches de protection holographique, comme décrit par exemple dans le document de brevet EP 0 708 935 . Cette opération peut être réalisée par transfert d'un ensemble de couches de protection, par exemple lors d'une étape de laminage.To authenticate and protect these personalized data, it is known to cover the printed page - or data carrier - of a set of holographic protection layers, as described for example in the patent document. EP 0 708 935 . This operation can be performed by transferring a set of protective layers, for example during a rolling step.

Ces couches de protection comportent en outre des éléments optiques de sécurité constituant un laminat. Ces éléments optiques de sécurité sont constitués par un ou plusieurs films ou vernis de protection, une couche comportant une microstructure optique diffractante, une couche réfléchissante et une couche adhésive. Le laminat est collé à la page imprimée par la couche adhésive. Il est généralement de faible épaisseur afin de contrer les risques de falsification du document par arrachage du laminat. Avant le transfert sur la page imprimée, le laminat peut également comprendre un film support et une couche de séparation. Lors du transfert, toutes les couches du laminat sont transférées sur le document à protéger, à l'exception du film support et de la couche de séparation qui sont retirés. On dispose ainsi d'un document sécurisé comportant un support de données recouvert d'un composant optique comportant un ensemble de couches de protection holographique.These protective layers further comprise safety optical elements constituting a laminate. These optical security elements consist of one or more protective films or varnishes, a layer comprising a diffractive optical microstructure, a reflective layer and an adhesive layer. The laminate is glued to the printed page by the adhesive layer. It is generally thin in order to counter the risks of falsification of the document by tearing off the laminate. Prior to transfer to the printed page, the laminate may also include a support film and a release layer. During the transfer, all layers of the laminate are transferred to the document to be protected, except for the carrier film and the separating layer which are removed. There is thus a secure document comprising a data carrier covered with an optical component comprising a set of holographic protection layers.

Néanmoins, en dépit de la faible épaisseur des couches de protection, ce type de solution présente l'inconvénient de rendre trop facile la falsification par séparation du composant holographique par rapport au reste du document, en utilisant par exemple un solvant adéquat disponible sur le marché. La résistance à la falsification n'est donc pas suffisamment élevée avec ce type de solution.Nevertheless, despite the small thickness of the protective layers, this type of solution has the disadvantage of making it too easy to falsify by separating the holographic component with respect to the rest of the document, using for example a suitable solvent available on the market. . The resistance to forgery is therefore not high enough with this type of solution.

Une solution pour renforcer la prévention contre l'arrachage du composant holographique est proposée dans le document de brevet US 2007/246931 . Dans cette publication, un document d'identité comporte des données de personnalisation imprimées ou collées sur un support de données. Il comprend également des couches de protection holographiques ainsi qu'un circuit électronique disposé sur le support de données et permettant une identification par radiofréquence. Les couches de protection et le circuit électronique sont recouverts d'un film. La séparation des couches de protection et du circuit électronique est alors rendue impossible sans détruire de manière irréversible le film recouvrant le circuit. La détection de la destruction de ce film est suffisamment facile pour que l'on puisse reconnaître de manière immédiate une falsification.A solution to strengthen the prevention against tearing of the holographic component is proposed in the patent document US 2007/246931 . In this publication, an identity document includes personalization data printed or pasted on a data carrier. It also includes holographic protection layers and an electronic circuit disposed on the data carrier and allowing radio frequency identification. The protective layers and the electronic circuit are covered with a film. The separation of the protective layers and the electronic circuit is then made impossible without irreversibly destroying the film covering the circuit. The detection of the destruction of this film is sufficiently easy so that one can immediately recognize a falsification.

Cette solution présente toutefois l'inconvénient de nécessiter l'utilisation de moyens électroniques qui engendrent, d'une part, un coût supplémentaire significatif du document et, d'autre part, une plus grande complexité de fabrication. Un document sécurisé est divulgué dans DE 10 2004 014778 A1 .However, this solution has the disadvantage of requiring the use of electronic means which generate, on the one hand, a significant additional cost of the document and, on the other hand, greater manufacturing complexity. A secure document is disclosed in DE 10 2004 014778 A1 .

Ainsi, aucune solution de l'état de la technique ne permet de fournir une résistance élevée à la falsification par arrachage de composants holographiques de protection, tout en étant peu coûteux et facile à fabriquer.Thus, no solution of the state of the art can provide a high resistance to falsification by tearing holographic protective components, while being inexpensive and easy to manufacture.

La présente invention propose de remédier à ce problème technique, en utilisant au moins une perforation pratiquée dans le support de données et en disposant, en plus du premier composant optique disposé sur une face du support de données, un deuxième composant de scellage sur l'autre face du support. Ces deux composants, comportant chacun une couche adhésive, recouvrent entièrement une perforation et se collent l'un à l'autre au niveau de celle-ci, ce qui permet de les sceller de part et d'autre du support.The present invention proposes to overcome this technical problem, by using at least one perforation made in the data carrier and having, in addition to the first optical component disposed on one side of the data carrier, a second sealing component on the other side of the support. These two components, each having an adhesive layer, completely cover a perforation and are bonded to one another at the level of the latter, which allows them to be sealed on either side of the support.

L'approche de la solution a consisté à chercher des moyens pour empêcher l'arrachage du composant optique de sécurité sans l'endommager de manière irréversible. Il est alors apparu que le recouvrement adhésif de chaque face du support de données par deux composants, combiné à une ou plusieurs perforations pratiquées uniquement dans le support, permettait un scellage du composant optique de sécurité peut coûteux et facile à mettre en oeuvre de manière industrielle.The approach of the solution was to look for ways to prevent tearing of the optical security component without irreversibly damaging it. It then appeared that the adhesive covering of each face of the data carrier by two components, combined with one or more perforations made solely in the support, made it possible to seal the security optical component which can be expensive and easy to implement industrially. .

Dans ce but, l'invention a pour objet un document sécurisé comprenant un support de données et un composant optique de sécurité, le support comprenant une première face et une deuxième face, le composant optique comprenant des moyens aptes à générer des effets optiques et des moyens adhésifs adhérant à la première face de ce support, des données de personnalisation étant inscrites sur ce document sécurisé,. Ce document sécurisé comprend également un composant additionnel de scellage comprenant des moyens adhésifs adhérant à la deuxième face de ce support, ce support comportant au moins une perforation disposée de sorte que ces composants optique et additionnel soient collés l'un à l'autre au travers de la perforation.For this purpose, the subject of the invention is a secure document comprising a data medium and an optical security component, the medium comprising a first face and a second face, the optical component comprising means capable of generating optical effects and adhesive means adhering to the first side of this support, personalization data being written on this secure document. This secure document also comprises an additional sealing component comprising adhesive means adhering to the second face of this support, this support comprising at least one perforation disposed so that these optical and additional components are glued to each other through the perforation.

Par la disposition d'une perforation et de deux composants recouvrant entièrement celle-ci et étant disposés de part et d'autre du support de données, on réalise ainsi un scellage des deux composants. Dès lors, lorsqu'un falsificateur essaiera d'arracher le composant optique - comportant un matériel holographique - du support de données, le composant additionnel sera également arraché du fait de ce scellage, ce qui va donc entraîner l'arrachage du document sécurisé tout entier. Par ailleurs les données de personnalisation imprimées sur le composant de sécurité à l'endroit de la perforation seront également détruites.By arranging a perforation and two components completely covering the latter and being arranged on either side of the data carrier, the two components are thus sealed. Therefore, when a falsifier tries to tear the optical component - including a holographic material - from the data carrier, the additional component will also be torn off because of this sealing, which will cause the entire secure document to be pulled out. . In addition, the personalization data printed on the security component at the point of perforation will also be destroyed.

De préférence, des données de personnalisation sont inscrites sur au moins l'un parmi le composant optique et le composant additionnel au niveau d'au moins une perforation au travers de laquelle sont collés l'un à l'autre les composants optique et additionnel. On dispose ainsi, au niveau d'une perforation, d'un contrôle en transparence d'un élément de sécurité supplémentaire. La vérification de ce nouvel élément s'opère simplement par l'observation des données de sécurité imprimées sur l'un des composants par transparence à travers la perforation. Dans le cas d'un passeport, ces données de sécurité peuvent être personnalisées, par exemple un identifiant ou une photo d'identité. De plus, si un falsificateur tente d'arracher le composant optique en ayant préalablement découpé la partie des composants disposés au niveau de la perforation, il sera facile de détecter, en transparence, l'absence de cette donnée de sécurité supplémentaire. La détection d'une telle falsification est ainsi rendue immédiate.Preferably, personalization data is written on at least one of the optical component and the additional component at at least one perforation through which the optical and additional components are glued to each other. This provides, at the level of a perforation, a transparency control of an additional security element. The verification of this new element is done simply by observing the security data printed on one of the components by transparency through the perforation. In the case of a passport, this security data can be personalized, for example an identifier or a photo ID. In addition, if a falsifier attempts to pull the optical component having previously cut the portion of the components disposed at the perforation, it will be easy to detect, in transparency, the absence of this additional security data. The detection of such falsification is thus made immediate.

On entendra par perforation une ouverture ou une encoche pratiquée sur le support de données. Ainsi cette perforation peut être disposé sur un bord du support - et n'est donc pas entièrement entourée par le support - ou ailleurs.Perforation will be understood to mean an opening or a notch made on the data carrier. Thus this perforation can be disposed on an edge of the support - and is not entirely surrounded by the support - or elsewhere.

Selon un mode particulier de réalisation, au moins une perforation au travers de laquelle sont collés l'un à l'autre les composants optique et additionnel est une ouverture disposée à l'intérieur de la surface du support.According to a particular embodiment, at least one perforation through which the optical and additional components are glued to each other is an opening disposed inside the surface of the support.

Selon un autre mode particulier de réalisation, au moins une perforation au travers de laquelle sont collés l'un à l'autre les composants optique et additionnel est une encoche disposée sur un bord de la surface du support.According to another particular embodiment, at least one perforation through which the optical and additional components are glued to each other is a notch disposed on an edge of the surface of the support.

Préférentiellement, les moyens adhésifs du composant optique comprennent une couche adhésive transparente.Preferably, the adhesive means of the optical component comprise a transparent adhesive layer.

Les moyens du composant optique aptes à générer des effets optiques comprennent préférentiellement une couche transparente réfléchissante et une couche estampée comportant une structure optique à microreliefs.The means of the optical component capable of generating optical effects preferably comprise a reflective transparent layer and a stamped layer comprising a microrelief optical structure.

Selon un mode particulier de réalisation, cette structure optique est constituée d'un réseau de diffraction produisant des effets de diffraction visibles à l'ordre zéro ou à l'ordre un.According to a particular embodiment, this optical structure consists of a diffraction grating producing visible diffraction effects at the zero order or the order one.

De manière avantageuse, la structure optique est agencée par rapport à la couche transparente réfléchissante de sorte à structurer une surface de la couche transparente réfléchissante.Advantageously, the optical structure is arranged with respect to the reflective transparent layer so as to structure a surface of the reflective transparent layer.

De manière également avantageuse, la couche transparente réfléchissante est superposée à la couche adhésive transparente et la couche estampée est superposée à la couche transparente réfléchissante. Cette couche transparente réfléchissante peut être formée en un matériau diélectrique transparent.Also advantageously, the reflective transparent layer is superimposed on the transparent adhesive layer and the stamped layer is superimposed on the transparent reflective layer. This reflective transparent layer may be formed of a transparent dielectric material.

Le composant optique comprend également, préférentiellement, au moins un film présentant une résistance mécanique de protection, afin de la protéger de dommages éventuels.The optical component also preferably comprises at least one film having a mechanical strength of protection, in order to protect it from possible damage.

Selon un mode de réalisation préféré, le composant additionnel comporte également des moyens aptes à générer des effets optiques. On dispose ainsi d'une sécurisation optique sur chacune des faces du document, ce qui renforce encore sa sécurité.According to a preferred embodiment, the additional component also comprises means able to generate optical effects. We have optical security on each side of the document, which further enhances its security.

Selon un autre mode de réalisation préféré, la première face et la deuxième face du support sont entièrement recouvertes respectivement par les composants optique et additionnel. Cela permet, d'une part, de protéger le support de données dans son intégralité et, d'autre part, de disposer d'une plus grande surface pour les deux composants, ce qui rend d'autant plus difficile l'arrachage d'une telle surface.According to another preferred embodiment, the first face and the second face of the support are completely covered respectively by the optical and additional components. This makes it possible, on the one hand, to protect the data carrier in its entirety and, on the other hand, to have a larger surface area for the two components, which makes it more difficult to pull the such a surface.

De préférence, au moins l'un parmi le composant optique et le composant additionnel comporte au moins une couche épaisse. On rend le document sécurisé plus épais et donc plus maniable. De plus, cette épaisseur permet de compenser les trous provoqués par les perforations, ce qui évite que ces perforations puissent être perçues. Dans le cas où un seul composant porte un matériel holographique, la couche épaisse est préférentiellement disposée au niveau du composant qui ne porte pas de matériel holographique. Il est en effet préférable de disposer d'un composant holographique de faible épaisseur pour rendre d'autant plus difficile son arrachage. Dans le cas où les deux composants portent un matériel holographique, il est ainsi préférable de transférer le film mince sur la face comportant la photo.Preferably, at least one of the optical component and the additional component comprises at least one thick layer. It makes the document secure thicker and therefore more manageable. In addition, this thickness makes it possible to compensate for the holes caused by the perforations, which prevents these perforations from being perceived. In the case where a single component carries a holographic material, the thick layer is preferably disposed at the component which does not carry holographic material. It is indeed preferable to have a thin holographic component to make it more difficult pulling. In the case where the two components carry a holographic material, it is thus preferable to transfer the thin film on the side having the photo.

De manière avantageuse, le document sécurisé comporte également une antenne. Cette antenne permet de réaliser de l'amplification de signal en vue de communiquer avec une puce sans contact. Dans le cas d'un passeport, cette puce peut être par exemple intégrée dans la couverture de celui-ci ou dans une couche épaisse.Advantageously, the secure document also includes an antenna. This antenna makes it possible to carry out signal amplification in order to communicate with a contactless chip. In the case of a passport, this chip can be for example integrated in the cover thereof or in a thick layer.

Selon un mode particulier de réalisation, le support est un support imprimable par impression fixe. Le support est donc apte à permettre l'inscription de données de personnalisation sur au moins une face de celui-ci.According to a particular embodiment, the medium is a printable medium by fixed printing. The medium is therefore able to allow the registration of personalization data on at least one face thereof.

Selon un autre mode particulier de réalisation, les moyens adhésifs du composant optique sont constitués d'une couche adhésive transparente réactivable à chaud et imprimable par impression variable. Cette couche rend ainsi possible l'impression de données de personnalisation sur celle-ci avant qu'elle ne soit collée au support de données. Il peut donc être choisi d'imprimer des données sur la première face du support de données ou sur la couche adhésive du composant optique.According to another particular embodiment, the adhesive means of the optical component consist of a transparent adhesive layer hot-swappable and printable by variable printing. This layer thus makes it possible to print personalization data on it before it is glued to the data medium. It may therefore be chosen to print data on the first side of the data medium or on the adhesive layer of the optical component.

Selon un autre mode particulier de réalisation, les moyens adhésifs du composant additionnel sont constitués d'une couche adhésive transparente réactivable à chaud et imprimable par impression variable. Cette couche rend ainsi possible l'impression de données de personnalisation sur celle-ci avant qu'elle ne soit collée au support de données. Des données peuvent donc être imprimées sur la deuxième face du support de données ou sur la couche adhésive du composant additionnel en vue de multiplier le nombre de données de personnalisation visibles au travers de la perforation.According to another particular embodiment, the adhesive means of the additional component consist of a transparent heat-reactive adhesive layer that can be printed by variable printing. This layer thus makes it possible to print personalization data on it before it is glued to the data medium. Data can therefore be printed on the second side of the data medium or on the adhesive layer of the additional component in order to multiply the number of personalization data visible through the perforation.

Des données de personnalisation de sécurité peuvent ainsi être imprimées à la fois sur le support de données et sur chacun des deux composants, ce qui renforce d'autant plus la sécurité du document de par la multiplication des supports sur lesquels sont inscrits des données de personnalisation.Security customization data can thus be printed on both the data carrier and on each of the two components, which further enhances the security of the document by the multiplication of media on which are recorded personalization data. .

Parmi les données de personnalisation, certaines sont des données visibles, ce qui permet de disposer immédiatement et de façon lisible de données d'identification primordiales, comme par exemple un nom, un identifiant ou une photo.Among the personalization data, some are visible data, which makes it possible to have immediate and identifiable identification data immediately, such as a name, an identifier or a photo.

Selon un mode particulier de réalisation, des données de personnalisation sont invisibles. L'utilisation d'une encre de sécurité apporte encore une sécurité supplémentaire au document. L'encre de sécurité utilisée peut avoir une longueur d'onde par exemple dans l'infrarouge ou l'ultraviolet. Un moyen de lecture adapté à la longueur d'onde choisie est alors requis.According to a particular embodiment, personalization data is invisible. The use of a security ink adds additional security to the document. The security ink used may have a wavelength for example in the infrared or the ultraviolet. A reading means adapted to the chosen wavelength is then required.

Dans tous les modes de réalisation mentionnées ci-dessus, le support de données peut être notamment en papier ou en plastique (par exemple du polycarbonate).In all the embodiments mentioned above, the data carrier may be in particular paper or plastic (for example polycarbonate).

L'invention concerne également un procédé pour sécuriser un document comprenant un support de données comprenant une première face et une deuxième face. Ce procédé comprend un étape d'inscription de données de personnalisation sur le document et une étape de transfert d'un composant optique de sécurité sur la première face du support, le composant optique comprenant des moyens aptes à générer des effets optiques et des moyens adhésifs adhérant à la première face de ce support. Selon l'invention, ce procédé comprend également une étape préalable de perforation du support et une étape de transfert d'un composant additionnel de scellage sur la deuxième face du support, le composant additionnel comprenant des moyens adhésifs adhérant à la deuxième face du support, de sorte que les composants optique et additionnel transférés soient collés l'un à l'autre au travers d'au moins une perforation.The invention also relates to a method for securing a document comprising a data medium comprising a first face and a second face. This method comprises a step of writing personalization data to the document and a step of transferring a security optical component to the first face of the medium, the optical component comprising means capable of generating optical effects and adhesive means. adhering to the first side of this support. According to the invention, this method also comprises a prior step of perforating the support and a step of transferring an additional sealing component to the second face of the support, the additional component comprising adhesive means adhering to the second face of the support, so that the transferred optical and additional components are glued to each other through at least one perforation.

De préférence, préalablement aux étapes de transfert du composant optique et du composant additionnel, une étape d'inscription de données de personnalisation sur l'un parmi le composant optique et le composant additionnel au niveau d'au moins une perforation au travers de laquelle seront collés l'un à l'autre les composants optique et additionnel transférés. Cette inscription de données supplémentaires permettra, une fois le document sécurisé, de disposer d'un moyen supplémentaire de vérification, qui sera opéré par simple observation de ces données en transparence au travers de la perforation concernée.Preferably, prior to the transfer steps of the optical component and the additional component, a personalization data registration step on one of the optical component and the additional component at the level of at least one perforation through which will be glued to each other the optical and additional components transferred. This registration of additional data will, once the secure document, to have an additional means of verification, which will be operated by simple observation of these data in transparency through the perforation concerned.

De préférence également, les étapes de transfert du composant optique et du composant additionnel sont réalisées simultanément à partir d'un support de transfert sur lequel sont disposés les composants optique et additionnel de part et d'autre d'une ligne de pliage. On dispose ainsi d'un seul support de transfert pour les deux composants, ce qui permet non seulement d'économiser du support de composant et également de positionner correctement les deux composants de part et d'autre de la ligne de pliage par rapport au support de données en vue de leur transfert sur celui-ci. Le pliage du support de transfert permet de disposer les deux composants en vis-à-vis de part et d'autre du support à protéger. De plus, cela permet de réaliser simultanément les deux étapes de transfert en une seule étape. On s'assure également que les deux couches adhésives 5 et 10 soient activées en même temps et ainsi que le collage s'opère aussi bien au niveau des deux faces du support qu'au niveau d'une perforation de fixation des deux composants l'un à l'autre.Also preferably, the steps of transferring the optical component and the additional component are performed simultaneously from a transfer medium on which are disposed the optical and additional components on either side of a fold line. There is thus a single transfer medium for the two components, which not only saves component support and also correctly position the two components on either side of the fold line relative to the support data for transfer to it. Folding the transfer support makes it possible to arrange the two components facing each other on either side of the support to be protected. In addition, this makes it possible to simultaneously perform the two transfer steps in a single step. It is also ensured that the two adhesive layers 5 and 10 are activated at the same time and that the bonding is effected as well at the two faces of the support as at the level of a fixing perforation of the two components. one to another.

Selon un mode particulier de mise en oeuvre du procédé selon l'invention, l'étape de transfert du composant optique consiste à préparer un film de transfert comprenant un film support enduit d'une couche de séparation elle-même enduite du composant optique, à appliquer le film de transfert sur la première face du support, puis à retirer le film support et la couche de séparation du film de transfert au niveau de la couche de séparation.According to a particular mode of implementation of the method according to the invention, the step of transferring the optical component consists in preparing a transfer film comprising a support film coated with a separation layer itself coated with the optical component, at applying the transfer film on the first side of the support, then removing the support film and the separating layer of the transfer film at the separation layer.

Selon un autre mode particulier, le composant optique est obtenu par enduction, sur un film présentant une résistance mécanique de protection, d'une couche estampée d'une structure optique en microreliefs, d'une couche transparente réfléchissante et d'une couche adhésive.According to another particular embodiment, the optical component is obtained by coating, on a film having a mechanical strength of protection, a stamped layer of a microrelief optical structure, a reflective transparent layer and an adhesive layer.

DESCRIPTION DETAILLEE D'UN MODE DE REALISATIONDETAILED DESCRIPTION OF AN EMBODIMENT

Comme illustré figure 1, qui représente une vue de dessus de la première face du document sécurisé 1 selon l'invention, ce document comprend un support de données 2 et un composant optique 3 de sécurité.As illustrated figure 1 , which represents a view from above of the first face of the secure document 1 according to the invention, this document comprises a data carrier 2 and an optical security component 3.

Dans un exemple particulier de réalisation de l'invention, le document sécurisé 1 est un document personnel associé à un porteur du type passeport, carte d'identité ou permis de conduire. Le support 2 correspond alors à une page ou une feuille de ce document sécurisé 1. Le support 2 peut être en différents matériaux, selon la nature du document sécurisé 1, et notamment en papier ou en plastique (par exemple en polycarbonate).In a particular embodiment of the invention, the secure document 1 is a personal document associated with a carrier such as passport, identity card or driver's license. The support 2 then corresponds to a page or a sheet of this secure document 1. The support 2 may be in different materials, depending on the nature of the secure document 1, and in particular paper or plastic (for example polycarbonate).

Le support 2 comprend une première face 12 et une deuxième face 13. Seule la première face 12 est visible sur la figure 1, la deuxième face 13 étant représentée sur la figure 2. Des données de personnalisation 16, 17, 18 et 19 sont inscrites sur la première face 12 du support 2. Ces données de personnalisation sont imprimées sur le support 2 par impression fixe. Elles sont choisies de sorte à fournir des informations personnelles sur le titulaire du document sécurisé, par exemple une photo du titulaire, des coordonnées civiles (nom, prénom, adresse, date de naissance, etc.), des identifiants, etc.The support 2 comprises a first face 12 and a second face 13. Only the first face 12 is visible on the figure 1 , the second face 13 being represented on the figure 2 . Personalization data 16, 17, 18 and 19 are written on the first face 12 of the support 2. These personalization data are printed on the support 2 by fixed printing. They are chosen to provide personal information about the holder of the secure document, such as a photo of the holder, civil details (name, surname, address, date of birth, etc.), identifiers, etc.

Selon l'invention, le support 2 comporte au moins une perforation 14. Une telle perforation se présente sous la forme d'une ouverture 14 pratiquée à l'intérieur du support 2, dans son épaisseur. Elle est utilisée pour le scellage du document sécurisé 1. Elle peut être complétée d'autres perforations, comme par exemple une encoche 15 sur un bord du support 2, dans son épaisseur.According to the invention, the support 2 comprises at least one perforation 14. Such a perforation is in the form of an opening 14 made inside the support 2, in its thickness. It is used for sealing the secure document 1. It can be completed with other perforations, such as for example a notch 15 on an edge of the support 2, in its thickness.

Le composant optique 3 de sécurité se présente sous la forme d'un film transparent ou partiellement transparent, recouvrant la première face 12 du support 2, préférentiellement sur toute sa surface. Il est agencé de sorte à recouvrir entièrement au moins les perforations 14 et 15 qui servent au scellage du document sécurisé 1. Ce composant 3 constitue un laminat à coller sur un document ou un produit de manière à le protéger de l'usure naturelle (résistance physico-chimique) et également d'empêcher une dégradation volontaire des éléments protégés par le film.The optical security component 3 is in the form of a transparent or partially transparent film, covering the first face 12 of the support 2, preferably over its entire surface. It is arranged so as to completely cover at least the perforations 14 and 15 which serve for sealing This component 3 constitutes a laminate to be bonded to a document or a product so as to protect it from natural wear (physicochemical resistance) and also to prevent a deliberate degradation of the elements protected by the film.

D'un point de vue industriel, une pluralité de composants 3 peuvent être fabriqués en série sur un même support (film ou papier) pour stockage. Le composant 3 à utiliser pour sécuriser le document 1 est ensuite décollé de ce support de stockage pour être amené jusqu'à ce document 1 à sécuriser via un support intermédiaire 24.From an industrial point of view, a plurality of components 3 can be manufactured in series on the same support (film or paper) for storage. The component 3 to be used to secure the document 1 is then detached from this storage medium to be brought to this document 1 to secure via an intermediate support 24.

En référence à la figure 3, le composant optique 3 comprend des moyens 21 aptes à générer des effets optiques, des moyens adhésifs 5 adhérant à la première face 12, ainsi que des moyens de protection 9.With reference to the figure 3 the optical component 3 comprises means 21 capable of generating optical effects, adhesive means 5 adhering to the first face 12, and protection means 9.

Les moyens adhésifs 5 sont constitués d'une couche adhésive transparente 5, réalisée par exemple en une colle transparente aux signaux lumineux dans le domaine visible, réactivable à chaud et imprimable par impression variable.The adhesive means 5 consist of a transparent adhesive layer 5, made for example of an adhesive transparent to visible light signals, hot-reactivatable and printable by variable printing.

Les moyens de protection 9 sont constitués d'un vernis de protection 9 recouvrant l'ensemble de la surface extérieure du composant optique 3 de sorte à le protéger. Le vernis utilisé présente pour cela une résistance aux rayures et aux produits chimiques.The protection means 9 consist of a protective varnish 9 covering the entire outer surface of the optical component 3 so as to protect it. For this purpose, the varnish used is resistant to scratches and chemicals.

Les moyens 21 aptes à générer des effets optiques comprennent une couche transparente réfléchissante 8 et une couche estampée 6. La couche estampée 6 comporte une structure optique 7 à microreliefs apte à produire des effets de diffraction ou holographiques. La couche 6 peut ainsi être une couche d'estampage ou une couche thermoformable. Ces moyens 21 sont préférentiellement superposés à une partie des données de personnalisation inscrites sur le document.The means 21 capable of generating optical effects comprise a reflective transparent layer 8 and a stamped layer 6. The embossed layer 6 comprises an optical structure 7 with microreliefs capable of producing diffraction or holographic effects. Layer 6 can thus be a stamping layer or a thermoformable layer. These means 21 are preferably superimposed on a portion of the personalization data included in the document.

La structure optique 7 est préférentiellement constituée d'un réseau de diffraction produisant des effets de diffraction visibles à l'ordre zéro ou à l'ordre un, ou tout autre microstructure optique produisant de tels effets.The optical structure 7 is preferably constituted by a diffraction grating producing visible diffraction effects at zero order or order one, or any other optical microstructure producing such effects.

La couche transparente estampée 6 est superposée à la couche réfléchissante 8, elle-même superposée à la couche adhésive 5. La structure optique 7 s'étend à l'interface entre la couche estampée 6 et la couche réfléchissante 8, de sorte que la couche réfléchissante 8 soit elle-même microstructurée en surface. Dès lors, la couche réfléchissante 8 est de préférence transparente sur son épaisseur.The stamped transparent layer 6 is superimposed on the reflective layer 8, itself superimposed on the adhesive layer 5. The optical structure 7 extends at the interface between the embossed layer 6 and the reflective layer 8, so that the layer reflective 8 is itself microstructured surface. Therefore, the reflective layer 8 is preferably transparent over its thickness.

La couche réfléchissante 8 est par exemple une couche d'un matériau diélectrique du type ZnS déposée par évaporation sous vide ou tout autre procédé connu. Elle peut être également de nature métallique et peut être appliquée de manière non uniforme. La nature et l'épaisseur de cette couche réfléchissante 8 sont adaptées à l'effet optique généré par la couche estampée 6.The reflective layer 8 is for example a layer of a dielectric material of ZnS type deposited by vacuum evaporation or any other known method. It may also be metallic in nature and may be applied in a non-uniform manner. The nature and the thickness of this reflective layer 8 are adapted to the optical effect generated by the embossed layer 6.

Dans un autre mode de réalisation de l'invention, les données de personnalisation 16, 17, 18 et 19 sont imprimées non pas sur le support 2 par impression fixe mais sur la couche adhésive 5 du composant optique 3 par impression variable. Il peut être également prévu d'imprimer une partie des données sur le support 2 et le reste sur la couche adhésive 5.In another embodiment of the invention, the personalization data 16, 17, 18 and 19 are printed not on the support 2 by fixed printing but on the adhesive layer 5 of the optical component 3 by variable printing. It may also be planned to print part of the data on the support 2 and the rest on the adhesive layer 5.

Comme illustré figure 2, qui représente une vue de dessus de la deuxième face du document sécurisé 1 selon l'invention, le document comprend également un composant additionnel 4 de scellage. Ce composant supplémentaire se présente sous la forme d'un film transparent recouvrant la deuxième face 13 du support 2, préférentiellement sur toute sa surface. De la même façon que le composant optique 3, le composant additionnel 4 est agencé de sorte à recouvrir entièrement au moins les perforations 14 et 15 qui servent au scellage du document sécurisé 1.As illustrated figure 2 , which represents a view from above of the second face of the secure document 1 according to the invention, the document also comprises an additional sealing component 4. This additional component is in the form of a transparent film covering the second face 13 of the support 2, preferably over its entire surface. In the same way as the optical component 3, the additional component 4 is arranged so as to completely cover at least the perforations 14 and 15 which serve to seal the secure document 1.

D'un point de vue industriel, les composants additionnels 4 peuvent être stockés de façon similaire aux composants optiques 3.From an industrial point of view, the additional components 4 can be stored similarly to the optical components 3.

En référence à la figure 3, le composant additionnel 4 comprend des moyens adhésifs 10 et des moyens de protection 11. Les moyens adhésifs 10 sont constitués d'une couche adhésive transparente 10, réalisée par exemple en une colle similaire à celle utilisée pour la couche adhésive transparente 5. Les moyens de protection 11 sont constitués d'un film présentant une résistance mécanique de protection 11 recouvrant l'ensemble de la surface extérieure du composant additionnel 4 de sorte à le protéger.With reference to the figure 3 the additional component 4 comprises adhesive means 10 and protection means 11. The adhesive means 10 consist of a transparent adhesive layer 10, made for example of a glue similar to that used for the transparent adhesive layer 5. The means 11 of protection consist of a film having a mechanical strength of protection 11 covering the entire outer surface of the additional component 4 so as to protect it.

Le composant optique 3 et le composant additionnel 4 entrent ainsi en contact au niveau des perforations 14 et 15, par l'intermédiaire de leurs couches adhésives respectives 5 et 10. Ces couches 5 et 10 sont susceptibles de se déformer au niveau des perforations de sorte à venir se coller l'une à l'autre, ce qui permet de coller le composant optique 3 et le composant additionnel 4 l'un à l'autre au travers de ces perforations. Dès lors, lorsqu'un falsificateur procédera à la séparation du composant optique 3 de sécurité, le composant additionnel 4 auquel il est scellé sera également arraché, ce qui engendra une dégradation irréversible du composant optique 3 et plus généralement du document sécurisé 1.The optical component 3 and the additional component 4 thus come into contact at the perforations 14 and 15, through their respective adhesive layers 5 and 10. These layers 5 and 10 are capable of deforming at the perforations so to stick to each other, which allows to glue the optical component 3 and the additional component 4 to each other through these perforations. Therefore, when a falsifier proceeds to separate the optical security component 3, the additional component 4 to which it is sealed will also be torn off, which causes an irreversible degradation of the optical component 3 and more generally the secure document 1.

Le terme perforation désigne aussi bien une ouverture qu'une encoche dans l'épaisseur du support. L'homme de métier comprendra que plus les dimensions des perforations seront grandes, plus la surface de scellage entre les deux composants sera grande, et donc plus le scellage de sécurité sera efficace.The term perforation designates both an opening and a notch in the thickness of the support. It will be appreciated by those skilled in the art that the larger the size of the perforations, the greater the sealing area between the two components will be, and thus the safety seal will be effective.

On décrit maintenant des modes de réalisation avantageux de invention, toujours en référence aux figures 1 à 3.Advantageous embodiments of the invention are now described, again with reference to Figures 1 to 3 .

Le document sécurisé comprend des données de personnalisation 19 au niveau de l'ouverture 14. Ces données 19 sont inscrites sur le composant optique 3 ou sur le composant additionnel 4, par impression variable. Ces données 19 peuvent être par exemple une photo du titulaire du document ou un identifiant. Cette partie du document peut alors être vérifiée simplement par transparence, ce qui offre une sécurité supplémentaire au document 1 en exploitant au mieux les perforations pratiquées dans celui-ci.The secure document comprises personalization data 19 at the aperture 14. This data 19 is written on the optical component 3 or on the additional component 4, by variable printing. This data 19 may be for example a photo of the document holder or an identifier. This part of the document can then be verified simply by transparency, which provides additional security to the document 1 by making the most of the perforations made in the document.

En pratiquant ainsi une perforation, sur laquelle on réalise en combinaison le scellage du composant optique par un composant additionnel au travers de la perforation et l'inscription de données de personnalisation de sécurité, on obtient un document sécurisé à la fois inarrachable et facile à vérifier en transparence, en plus de la sécurisation par holographie optique. Le document 1 est donc d'autant plus sécurisé.By practicing a perforation, in which the sealing of the optical component is performed in combination with an additional component through the perforation and the registration of security personalization data, a secure document is obtained that is both unobtrusive and easy to verify. in transparency, in addition to securing by optical holography. Document 1 is therefore all the more secure.

Selon d'autres modes de réalisation de l'invention, d'autres perforations peuvent être pratiquées dans le support 2 de données, des données de personnalisation supplémentaire étant disposées au niveau de chaque perforation. Le document en sera d'autant plus sécurisé en transparence et du point de vue de la prévention contre la fraude par arrachage.According to other embodiments of the invention, other perforations may be made in the data carrier 2, additional personalization data being disposed at each perforation. The document will be all the more secure in terms of transparency and from the point of view of the prevention against grubbing fraud.

Sur la deuxième face du document sécurisé 1 (figure 2), il peut être procédé à l'inscription de données de personnalisation 20, complémentaires des données de personnalisation 16, 17 et 18 de la première face 12 du document, ou similaires.On the second side of secure document 1 ( figure 2 ), it is possible to register personalization data 20 complementary to the personalization data 16, 17 and 18 of the first face 12 of the document, or the like.

Toujours sur cette deuxième face, il peut être ajouté une antenne 23 intégrée dans une couche épaisse du document sécurisé 1 telle que la couche 11. Dans le cas d'un passeport, il est également possible de l'intégrer dans sa couverture. Cette antenne 23 permet de communiquer avec une puce sans contact en vue de la détection d'un acte frauduleux par arrachage d'une partie du document, en complément du scellage du document par les perforations 14 et 15 et le composant additionnel 4.Still on this second face, it can be added an antenna 23 integrated in a thick layer of the secure document 1 such as the layer 11. In the case of a passport, it is also possible to integrate it into its cover. This antenna 23 makes it possible to communicate with a contactless chip in order to detect a fraudulent act by tearing off part of the document, in addition to sealing the document by the perforations 14 and 15 and the additional component 4.

L'inscription de plusieurs types de données de personnalisation 16, 17, 18, 19 et 20 sont possibles. En particulier, une partie des données de personnalisation est visible, ce qui permet d'en disposer immédiatement. D'autres sont invisibles, par l'utilisation d'une encre de sécurité avec une longueur d'onde dans l'infrarouge ou l'ultraviolet, ainsi que d'un moyen de lecture approprié. D'autres, enfin, sont réactivables, par l'utilisation d'un moyen de marquage réactivable et d'un moyen de réactivation approprié.The registration of several types of personalization data 16, 17, 18, 19 and 20 is possible. In particular, a part of the personalization data is visible, which makes it possible to dispose of it immediately. Others are invisible, by the use of a security ink with an infrared or ultraviolet wavelength, as well as an appropriate reading means. Others, finally, are reactivatable by the use of a reactivatable marking means and a suitable reactivation means.

On décrit maintenant un procéder pour sécuriser un document selon l'invention, en référence aux figures 4 et 5.We now describe a procedure for securing a document according to the invention, with reference to the figures 4 and 5 .

Le document de départ, non sécurisé, comprend un support 2 de données. Ce support comprend une première face 12 et une deuxième face 13. Pour obtenir un document sécurisé selon l'invention, il est nécessaire de procéder, en outre, à une perforation du support 2, ainsi qu'aux transferts du composant optique 3 de sécurité et du composant additionnel 4 de scellage.The starting document, unsecure, includes a data carrier 2. This support comprises a first face 12 and a second face 13. To obtain a secure document according to the invention, it is necessary to proceed, in addition, to a perforation of the support 2, as well as transfers of the optical component 3 security and additional sealing component 4.

Le composant optique 3 et le composant additionnel 4 ont des structures similaires à celles de ces mêmes composants décrits ci-dessus en référence aux figures 1 à 3.The optical component 3 and the additional component 4 have structures similar to those of these same components described above with reference to the Figures 1 to 3 .

La première étape est une étape de personnalisation, consistant en l'inscription de données de personnalisation 16, 17, 18, 19 et 20 sur le document. Ces données peuvent être inscrites directement sur l'une des faces - ou les deux - du support 2, sur la couche adhésive 5 du composant optique 3 et sur la couche adhésive 10 du composant additionnel 4. L'inscription se fait par impression fixe ou variable en fonction de la nature des éléments à imprimer. Par exemple, pour des questions d'esthétisme, on imprime en même temps le nom du champ et sa valeur (soit « NOM : DANIEL », etc.). L'inscription des éléments d'information fixes ou variables se fait, selon les cas, par une impression jet d'encre, laser ou autre.The first step is a personalization step, consisting of the enrollment of personalization data 16, 17, 18, 19 and 20 on the document. These data can be written directly on one or both sides of the support 2, on the adhesive layer 5 of the optical component 3 and on the adhesive layer 10 of the additional component 4. The inscription is done by fixed printing or variable depending on the nature of the elements to be printed. For example, for aesthetic reasons, we print at the same time the name of the field and its value (ie "NAME: DANIEL", etc.). The inscription of the fixed or variable information items is, depending on the case, by an inkjet, laser or other printing.

L'étape suivante consiste, préalablement au transfert des deux composants sur le support 2, à pratiquer une perforation 14 du support 2. Cette perforation 14 est une ouverture pratiquée dans l'épaisseur du support 2. Elle peut être complétée d'un certain nombre d'autres perforations, en vue de réaliser un scellage du document d'autant plus efficace.The following step consists, prior to the transfer of the two components on the support 2, to perforate the support 2. This perforation 14 is an opening made in the thickness of the support 2. It may be completed by a number other perforations, in order to achieve a seal of the document all the more effective.

Les étapes suivantes consistent à transférer le composant optique 3 et le composant additionnel 4 sur chacune des faces du support 2, le collage étant assuré par les couches adhésives 5 et 10 des deux composants.The following steps consist in transferring the optical component 3 and the additional component 4 on each of the faces of the support 2, the bonding being ensured by the adhesive layers 5 and 10 of the two components.

En référence à la figure 4, le transfert du composant optique 3 consiste à fixer sur le document à protéger, au cours d'une étape de laminage, les couches de protection, incluant notamment les moyens 21 aptes à générer des effets optiques. Avant transfert, le composant optique 3 - ou laminat - est supporté par un film support 26 enduit d'une couche de séparation 27. Dès lors, le film de transfert 25 ainsi réalisé comprend successivement un film support 26, une couche de séparation 27, une ou plusieurs couches de vernis de protection 9, un couche estampée 6 comportant une microstructure optique 7, une couche réflective 8 et une couche adhésive 5.With reference to the figure 4 , the transfer of the optical component 3 consists in fixing on the document to be protected, during a rolling step, the protective layers, including in particular the means 21 able to generate optical effects. Before transfer, the optical component 3 - or laminate - is supported by a support film 26 coated with a separation layer 27. As a result, the transfer film 25 thus produced successively comprises a support film 26, a separation layer 27, one or more layers of protective varnish 9, a stamped layer 6 having an optical microstructure 7, a reflective layer 8 and an adhesive layer 5.

Le film support 26 est constitué par exemple en polyester. Ce film polyester peut être disposé en bobine de 12 à 100 µm d'épaisseur, typiquement 19 µm. L'ensemble 25 est enduit d'un film adhésif sur la surface libre du film support 26 et d'un support siliconé de manière à pouvoir convertir le composant à transférer sous la forme d'une étiquette découpée au format à transférer sur le support siliconé, de sorte que le support siliconé comprenne un ensemble d'étiquettes afin de faciliter leur stockage et leur transfert ultérieur sur un support de type 24. La couche de séparation 27, par exemple formée de cire, sert au détachement ultérieur des couches à transférer.The support film 26 consists for example of polyester. This polyester film may be arranged in a coil of 12 to 100 microns thick, typically 19 microns. The assembly 25 is coated with an adhesive film on the free surface of the support film 26 and with a silicone support so as to be able to convert the component to be transferred in the form of a label cut to the format to be transferred onto the silicone support , so that the silicone support comprises a set of labels to facilitate their storage and their subsequent transfer on a type of support 24. The separating layer 27, for example formed of wax, serves for the subsequent detachment of the layers to be transferred.

Ces couches sont transférées sur le support 2 suivant des techniques de laminage bien connues de l'homme du métier. Lors du transfert, toutes ces couches sont transférées sur le document à protéger, à l'exception du film support 26 et de la couche de séparation 27 qui sont retirés. Ce retrait s'opère au niveau de la couche de séparation 27. Il ne reste alors collé à la première face 12 du support 2 que le composant optique 3.These layers are transferred to the support 2 according to rolling techniques well known to those skilled in the art. During the transfer, all these layers are transferred onto the document to be protected, except for the support film 26 and the separation layer 27 which are removed. This withdrawal takes place at the level of the separation layer 27. It then remains glued to the first face 12 of the support 2 that the optical component 3.

Le transfert du composant additionnel 4 peut s'opérer lors d'une étape de transfert similaire, sur la deuxième face 13 du support 2. Les étapes de transfert de chacun des deux composants peuvent être opérées successivement ou simultanément en fonction des moyens de laminage à disposition. Dans le cas d'une colle à chaud, le transfert des deux composants s'effectue en une seule étape. Dans le cas d'une colle à froid, le transfert peut s'effectuer en deux étapes, mais cette dernière possibilité présente un intérêt moindre puisqu'il est alors impossible de réaliser des impressions sur les composants.The transfer of the additional component 4 can take place during a similar transfer step, on the second face 13 of the support 2. The transfer steps of each of the two components can be performed successively or simultaneously depending on the rolling means to disposition. In the case of a hot glue, the transfer of the two components takes place in a single step. In the case of a cold glue, the transfer can be carried out in two stages, but this latter possibility is of less interest since it is impossible to print on the components.

L'homme du métier notera qu'il peut utiliser plusieurs types de matériau adhésif pour réaliser les couches adhésives 5 et 10 des deux composants, en particulier des colles transparents réactivables à chaud ou des colles transparentes que ne nécessitent pas de réactivation à chaud, autrement dit des adhésifs sensibles à la pression.Those skilled in the art will appreciate that they can use several types of adhesive material to make the adhesive layers 5 and 10 of the two components, especially heat-reactive clear adhesives or clear adhesives that do not require hot reactivation, otherwise says pressure-sensitive adhesives.

Après transfert des deux composants 3 et 4, ceux-ci sont collés l'un à l'autre au travers de la perforation 14, les couches adhésives 5 et 10 étant aptes à se déformer légèrement de sorte à pénétrer l'intérieur de la perforation 14 et ainsi rentrer en contact l'une avec l'autre. On obtient ainsi un scellage des deux composants, disposés de part et d'autre du support 2 de données.After transfer of the two components 3 and 4, they are glued to each other through the perforation 14, the adhesive layers 5 and 10 being able to deform slightly so as to penetrate the inside of the perforation 14 and thus come into contact with each other. This produces a seal of the two components, arranged on either side of the data carrier 2.

Lors de l'étape de personnalisation du document 1, des données de personnalisation 19 peuvent être inscrites sur l'une des couches adhésives 5 ou 10, par impression variable, au niveau d'une perforation 14. Ces données 19 sont destinées, après transfert des deux composants 3 et 4, à être vérifiées par lecture du document en transparence, ce qui offre une sécurité supplémentaire et parfaitement lisible au niveau de la zone de scellage. On exploite ainsi cette zone de scellage en combinant un scellage et une vérification sécuritaire en transparence.During the customization step of the document 1, personalization data 19 may be written on one of the adhesive layers 5 or 10, by variable printing, at a perforation 14. These data 19 are intended, after transfer two components 3 and 4, to be verified by reading the document in transparency, which provides additional security and perfectly legible at the sealing area. This sealing zone is thus exploited by combining a seal and a security verification in transparency.

En référence à la figure 5, selon un mode particulièrement avantageux de réalisation des étapes de transfert susmentionnées, celles-ci sont réalisées simultanément à partir d'un seul film support 24. Les deux composants 3 et 4 sont disposés de manière adéquate sur ce film 24, de part et d'autre d'une ligne de pliage 28. Le pliage du film support 24 au niveau de cette ligne de pliage 28 permet de recouvrir d'un seul coup les deux faces du support 2, et des techniques de laminage peuvent s'appliquer simultanément de chaque côté du document de sorte à opérer le transfert en même temps. Le film support 24, ainsi que la couche 26 et la couche de séparation 27 sont ensuite retirés de sorte à ne laisser que le composant 3. Une structure analogue permet de ne laisser que le composant 4 sur l'autre face. On évite de cette façon l'introduction d'étapes supplémentaires de fabrication. On s'assure également que les deux couches adhésives 5 et 10 soient activées en même temps et ainsi que le collage s'opère aussi bien au niveau des deux faces du support 2 qu'au niveau d'une perforation de fixation des deux composants l'un à l'autre.With reference to the figure 5 according to a particularly advantageous embodiment of the aforementioned transfer steps, these are carried out simultaneously from a single support film 24. The two components 3 and 4 are arranged adequately on this film 24, on both sides. Another of a folding line 28. The folding of the support film 24 at this fold line 28 makes it possible to cover the two faces of the support 2 in one go, and rolling techniques can be applied simultaneously to each side of the document to operate the transfer at the same time. The support film 24, as well as the layer 26 and the separation layer 27 are then removed so as to leave only the component 3. A similar structure allows to leave only the component 4 on the other side. This avoids the introduction of additional manufacturing steps. It is also ensured that the two adhesive layers 5 and 10 are activated at the same time and that the bonding is effected as well at the two faces of the support 2 as at the level of a fixing perforation of the two components. one to another.

Dans tous les modes de réalisation mentionnées ci-dessus, le support 2 peut être une page ou une feuille d'un document personnel comme une carte d'identité, un passeport ou un permis de conduire.In all the embodiments mentioned above, the support 2 may be a page or a sheet of a personal document such as an identity card, a passport or a driving license.

Les modes de réalisation précédemment décrits de la présente invention sont donnés à titre d'exemples et ne sont nullement limitatifs. Il est entendu que l'homme du métier est à même de réaliser différentes variantes de l'invention sans pour autant sortir du cadre du brevet.The previously described embodiments of the present invention are given by way of examples and are in no way limiting. It is understood that the skilled person is able to realize different variants of the invention without departing from the scope of the patent.

En particulier, il peut être prévu que l'élément de personnalisation inscrit sur la zone de perforation soit une photographie du titulaire du document, inscrite par exemple en miroir. Il peut être également prévu que les éléments optiques recouvrent la photographie du titulaire ainsi que les perforations nécessaires au scellage du document. Il peut enfin être prévu que des perforations prennent la forme de la carte géographique du pays dont est originaire le titulaire, lorsque le document sécurisé est de type passeport.In particular, it may be provided that the personalization element inscribed on the perforation zone is a photograph of the holder of the document, inscribed for example in mirror. It may also be provided that the optical elements cover the photograph of the holder and the perforations necessary for sealing the document. Lastly, it may be provided that perforations take the form of the geographical map of the country of origin of the holder, when the secure document is of the passport type.
