DESCRIPCIONDESCRIPTION
Documento de seguridad y procedimiento de verificacion de este documentoSecurity document and verification procedure of this document
La presente invencion se refiere al campo tecnico de los documentos de seguridad que se presentan en forma de una tarjeta que incluye un cuerpo ngido, incluso semirngido. Se aplica mas particularmente a unos documentos de seguridad como una tarjeta de identidad.The present invention relates to the technical field of security documents that are presented in the form of a card that includes a rigid body, even semi-rigid. It applies more particularly to security documents such as an identity card.
Por lo general, unas tarjetas de este tipo llevan unos datos personales espedficos del portador de la tarjeta, por ejemplo, unas inscripciones escritas, unas imagenes como una fotograffa del portador. Eventualmente, el documento de seguridad puede incluir otros datos, como unos datos de proteccion que consisten esencialmente en unos guilloches, un fondo numismatico, etc.In general, cards of this type carry specific personal data of the cardholder, for example, written inscriptions, images such as a photograph of the carrier. Eventually, the security document may include other data, such as protection data consisting essentially of guilloches, a numismatic background, etc.
Por tarjeta ngida, incluso semirngida, se entiende una tarjeta cuyo cuerpo es lo suficientemente ngido para impedir el plegado de la tarjeta sin danarla permitiendo, no obstante, al mismo tiempo una relativa flexion del cuerpo.A nigged card, even semi-rigid, means a card whose body is sufficiently sharp to prevent folding of the card without damaging it, however, allowing at the same time a relative flexion of the body.
En el campo de la identidad, la lucha contra los intentos de falsificacion y de copia ilegal es objeto de desarrollos de documentos de seguridad cada vez mas complejos.In the field of identity, the fight against attempts at counterfeiting and illegal copying is subject to increasingly complex security document developments.
Se conoce por el estado de la tecnica, en concreto por el documento WO 2009/007282 que se refiere mas particularmente al campo de los pasaportes, la ocultacion de una informacion sobre una de las paginas del pasaporte. Entonces, para revelar esta informacion oculta, es necesario disponer de un dispositivo revelador espedfico de la informacion oculta.It is known from the state of the art, in particular from WO 2009/007282 which refers more particularly to the field of passports, the concealment of information about one of the passport pages. Then, to reveal this hidden information, it is necessary to have a specific revealing device for the hidden information.
En este documento, el dispositivo revelador forma parte integrante del pasaporte y se presenta en forma de una pagina adicional que comprende unos medios adecuados para descodificar la informacion oculta.In this document, the revealing device is an integral part of the passport and is presented in the form of an additional page comprising adequate means to decode the hidden information.
No obstante, en el caso de una tarjeta, la incorporacion de un dispositivo de este tipo en el documento de seguridad resulta ser imposible de realizar. En este caso, el dispositivo revelador es completamente externo a la tarjeta.However, in the case of a card, the incorporation of such a device in the security document proves to be impossible. In this case, the developing device is completely external to the card.
Ahora bien, el inconveniente de recurrir a unos medios exteriores para verificar la autenticidad de la tarjeta es que la persona que se encarga de la verificacion puede estar desprovista de este dispositivo, por sencillo olvido, en concreto cuando se trata de una persona que trabaja en la red viaria, como un polida, que desea efectuar un control sorpresa durante una de sus misiones.However, the inconvenience of resorting to external means to verify the authenticity of the card is that the person in charge of the verification can be devoid of this device, by simple forgetfulness, specifically when it is a person who works in the road network, like a policeman, who wishes to carry out a surprise check during one of his missions.
El documento de los Estados Unidos US 2006/290136 A1 divulga algunas caractensticas del preambulo de la reivindicacion 1.United States document US 2006/290136 A1 discloses some features of the preamble of claim 1.
La invencion tiene como finalidad, en concreto, proponer un dispositivo de seguridad de tipo tarjetas ngidas, incluso seminigidas que permite resolver el inconveniente anteriormente citado para la autentificacion.The purpose of the invention is, in particular, to propose a security device of the type of nested cards, even seminigidas, which allows solving the aforementioned problem for authentication.
Para ello, la invencion tiene como objeto un documento de seguridad que tiene una forma general de tarjeta provisto de un cuerpo sustancialmente semirngido, incluso ngido, llevando la tarjeta unos datos, en concreto unos datos personales espedficos de un portador del documento de seguridad, caracterizado por que los datos incorporan una informacion codificada segun un tipo predefinido de codificacion, imperceptible a simple vista y por que la tarjeta lleva unos medios adecuados para revelar cualquier informacion codificada segun el tipo predefinido que lleva otra tarjeta.For this purpose, the invention has as its object a security document having a general form of card provided with a substantially semi-rigid body, even nested, carrying the card some data, specifically personal data specific to a holder of the security document, characterized because the data incorporates an encrypted information according to a predefined type of coding, imperceptible to the naked eye and why the card has adequate means to reveal any encrypted information according to the predefined type carried by another card.
Por el hecho de que la propia tarjeta lleva los medios de revelacion del tipo predefinido que corresponde al de la informacion oculta, cualquier tarjeta que pertenezca a un portador cualquiera puede permitir la autentificacion de la tarjeta de un primer portador.Due to the fact that the card itself carries the means of revelation of the predefined type corresponding to that of the hidden information, any card belonging to any carrier can allow the authentication of the card of a first carrier.
Por supuesto, por el hecho de la relativa rigidez de una tarjeta, es imposible plegarla para poder permitir una revelacion de la informacion oculta con los medios reveladores que son propios de la tarjeta. De esta manera, son necesarias dos tarjetas para permitir la autentificacion de una u otra.Of course, due to the relative rigidity of a card, it is impossible to fold it in order to allow a revelation of the hidden information with the revealing means that are characteristic of the card. In this way, two cards are necessary to allow the authentication of one or the other.
No obstante, cuando la tarjeta se refiere a un documento de seguridad como una tarjeta de seguro medico, una tarjeta de identidad, la probabilidad de que la persona que desea controlar la autenticidad de la tarjeta de un portador cualquiera sea portadora de una tarjeta que permite la verificacion de esta es relativamente alta.However, when the card refers to a security document such as a medical insurance card, an identity card, the probability that the person wishing to control the authenticity of any carrier's card bears a card that allows The verification of this is relatively high.
De esta manera, la tarjeta que hay que autentificar forma a la vez una herramienta que permite evitar la falsificacion por el hecho de la complejidad de realizacion de una tarjeta de este tipo y, ademas, un documento de seguridad que hay que identificar.In this way, the card to be authenticated forms both a tool that prevents counterfeiting due to the complexity of carrying out such a card and, in addition, a security document that must be identified.

Otras caractensticas y ventajas de la invencion se mostraran a la luz de la descripcion que sigue, hecha con referencia a los dibujos adjuntos en los que:Other features and advantages of the invention will be shown in light of the description that follows, made with reference to the accompanying drawings in which:
- la figura 1 representa un documento de seguridad segun la invencion;- Figure 1 represents a security document according to the invention;
- la figura 2 representa de forma esquematica unas etapas de fabricacion del documento de seguridad de la figura 1;- Figure 2 schematically represents manufacturing steps of the security document of Figure 1;
- la figura 3 ilustra los principales aspectos de funcionamiento del documento de la figura 1.- Figure 3 illustrates the main operational aspects of the document in Figure 1.
Sobre la figura 1, se ha representado un documento de seguridad segun la invencion. Este documento se designa mediante la referencia general 10.On figure 1, a security document according to the invention has been represented. This document is designated by general reference 10.
Este documento 10 tiene una forma general de tarjeta y esta provisto de un cuerpo 12 sustancialmente semirngido, incluso ngido. De esta manera, el cuerpo de tarjeta 12 es ligeramente deformable para permitir una ligera flexion del cuerpo. En cambio, por el hecho de esta rigidez relativa, el cuerpo de tarjeta 12 no puede plegarse sin riesgo de que se rompa o dane. El cuerpo 12 esta, por ejemplo, realizado con un material que comprende esencialmente policarbonato.This document 10 has a general card form and is provided with a substantially semi-rigid, even nested, body 12. In this way, the card body 12 is slightly deformable to allow slight flexion of the body. On the other hand, due to the fact of this relative stiffness, the card body 12 cannot be folded without risk of being broken or damaged. The body 12 is, for example, made of a material that essentially comprises polycarbonate.
En este ejemplo, el documento de seguridad es una tarjeta de identidad. Como variante, el documento de seguridad 10 puede ser un permiso de conducir o cualquier otra tarjeta que necesita una exigencia de seguridad.In this example, the security document is an identity card. As a variant, the security document 10 can be a driving license or any other card that needs a security requirement.
Como se representa esto en la figura 1, la tarjeta 10 lleva unos datos 14, en concreto unos datos personales espedficos de un portador del documento de seguridad 10. Por ejemplo, los datos comprenden una fotograffa 16 del portador de la tarjeta 10 o eventualmente una imagen, unos datos de identificacion 18 en forma de caracteres de imprenta. Preferentemente, el cuerpo 12 delimita dos caras opuestas de las que una de las dos al menos lleva los datos 14.As this is shown in Figure 1, the card 10 carries data 14, specifically personal data specific to a holder of the security document 10. For example, the data comprises a photograph 16 of the cardholder 10 or possibly a image, identification data 18 in the form of printing characters. Preferably, the body 12 delimits two opposite faces of which one of the two at least carries the data 14.
Aunque esto no este representado en las figuras, los datos 14 pueden comprender igualmente unos guilloches, es decir, unos trazados finos constituidos por lmeas continuas entrelazadas que forman unos motivos geometricos particularmente diffciles de reproducir.Although this is not represented in the figures, the data 14 may also include guilloches, that is, thin paths consisting of interlaced continuous lines that form geometrical patterns that are particularly difficult to reproduce.
Mas particularmente, los datos 14 comprenden una informacion oculta 20 imperceptible a simple vista. Por ejemplo, la informacion 20 se extiende parcialmente sobre la fotograffa 16 del portador.More particularly, the data 14 comprises hidden information 20 imperceptible to the naked eye. For example, the information 20 extends partially over the photograph 16 of the wearer.
En la figura 1, la informacion oculta 20 esta representada en forma punteada sobre la tarjeta 10. Queda entendido que esta informacion 20 es imperceptible o diffcilmente perceptible a simple vista.In Figure 1, the hidden information 20 is represented in dotted form on the card 10. It is understood that this information 20 is imperceptible or difficult to perceive with the naked eye.
De manera mas precisa, la informacion oculta 20 es de un tipo predefinido. Por informacion de un tipo predefinido, se entiende una informacion oculta segun una tecnica predefinida como, por ejemplo, una tecnica de polarizacion, deMore precisely, the hidden information 20 is of a predefined type. By information of a predefined type, hidden information is understood according to a predefined technique such as, for example, a polarization technique, of

esteganograffa o tambien de coloracion, etc. Cada informacion de un tipo predefinido, no perceptible a simple vista, necesita unos equipos de revelacion espedficos adaptados para la revelacion de una informacion de este tipo.Steganography or coloring, etc. Every information of a predefined type, not visible to the naked eye, needs specific revealing equipment adapted for the disclosure of such information.
En este ejemplo, la tarjeta 10 es dual. De esta manera, comprende un modulo de microcircuito 22 provisto de un campo de contactos externos 24 que asoman a la superficie del cuerpo de tarjeta 12 permitiendo una comunicacion con contacto por medio de un lector de tarjeta externo (no representado). Ademas, la tarjeta 10 comprende una antena 26 de comunicacion de campo proximo (en punteado en la figura 1) unida electricamente al microcircuito del modulo de microcircuito y que permite el establecimiento de una comunicacion sin contacto con un lector de tarjeta externo (no representado).In this example, card 10 is dual. In this way, it comprises a microcircuit module 22 provided with a field of external contacts 24 that appear on the surface of the card body 12 allowing communication with contact by means of an external card reader (not shown). In addition, the card 10 comprises a near-field communication antenna 26 (dotted in Figure 1) electrically connected to the microcircuit of the microcircuit module and allowing the establishment of a contactless communication with an external card reader (not shown) .
Como variante, la tarjeta 10 puede ser una tarjeta de tipo sin contacto, es decir, que solo permite una comunicacion sin contacto. En este caso, la tarjeta 10 esta desprovista de contactos externos y el modulo de microcircuito esta completamente incorporado en el cuerpo de tarjeta.As a variant, the card 10 can be a contactless type card, that is, it only allows a contactless communication. In this case, the card 10 is devoid of external contacts and the microcircuit module is completely incorporated in the card body.
Ademas, de conformidad con la invencion, la tarjeta 10 lleva unos medios 28 adecuados para revelar cualquier informacion oculta del tipo predefinido que lleva otra tarjeta.Furthermore, in accordance with the invention, the card 10 has adequate means 28 for revealing any hidden information of the predefined type carried by another card.
En este ejemplo, los medios de revelacion 28 comprenden una ventana transparente 30, eventualmente translucida, que se extiende por el espesor del cuerpo de tarjeta 12 de manera que deje pasar la luz a traves de la tarjeta 10.In this example, the revealing means 28 comprise a transparent, possibly translucent, window 30 that extends along the thickness of the card body 12 so that the light passes through the card 10.
Preferentemente, la informacion 20 esta codificada mediante una tecnica conocida de esteganograffa que consiste en codificar la informacion en un fondo mediante variaciones puntuales, por ejemplo, mediante unas lmeas moduladas a una frecuencia predefinida.Preferably, the information 20 is encoded by a known technique of steganography which consists in encoding the information in a background by point variations, for example, by means of lines modulated at a predefined frequency.
En este caso, los medios de revelacion 28 comprenden una red tramada de lmeas y/o de puntos adecuada para revelar una informacion oculta mediante la tecnica de la esteganograffa.In this case, the disclosure means 28 comprise a network of lines and / or points suitable for revealing hidden information by means of the technique of steganography.
Los medios de revelacion 28 comprenden, por ejemplo, una red de lmeas moduladas a una frecuencia sustancialmente igual a la frecuencia de disimulacion del mensaje. Preferentemente, la red tramada de lmeas esta impresa, o realizada en relieve, formando de esta manera una red lenticular.The disclosure means 28 comprise, for example, a network of lines modulated at a frequency substantially equal to the frequency of dissemination of the message. Preferably, the network of lines is printed, or made in relief, thus forming a lenticular network.
La red esta, por ejemplo, realizada con un material termoplastico. La red lenticular esta formada, por ejemplo, por una serie de lentes cilmdricas que funcionan sobre un solo eje. Con una red lenticular, es posible, por ejemplo, obtener un efecto de relieve, una animacion, etc.The network is, for example, made of thermoplastic material. The lenticular network is formed, for example, by a series of cylindrical lenses that operate on a single axis. With a lenticular network, it is possible, for example, to obtain a relief effect, an animation, etc.
Eventualmente, en una primera variante, los medios 28 comprenden un filtro polarizador adecuado para revelar una informacion oculta que comprende un elemento polarizado.Eventually, in a first variant, the means 28 comprise a polarizing filter suitable for revealing hidden information comprising a polarized element.
En una segunda variante, los medios 28 comprenden un filtro coloreado adecuado para revelar el o los colores con el que dicha informacion esta oculta esta formada.In a second variant, the means 28 comprise a colored filter suitable for revealing the color (s) with which said information is hidden is formed.
La tarjeta 10 esta fabricada de forma convencional mediante laminacion de capas de materia plastica entre sr De esta manera, preferentemente, como se ilustra esto en la figura 2, el cuerpo de tarjeta 12 esta formado por un conjunto laminado de un apilamiento de capas.The card 10 is conventionally manufactured by laminating layers of plastic material between sr. Thus, preferably, as this is illustrated in Figure 2, the card body 12 is formed by a laminated assembly of a layer stack.
De esta manera, como se ilustra esto en la figura 2, el apilamiento comprende al menos una capa central 32 que lleva la ventana transparente 30 intercalada entre al menos dos capas externas 34.Thus, as this is illustrated in Figure 2, the stack comprises at least one central layer 32 carrying the transparent window 30 sandwiched between at least two outer layers 34.
En este ejemplo, las capas externas 34 estan realizadas con un material transparente, mientras que la capa central 32 esta realizada con un material opaco a la luz.In this example, the outer layers 34 are made of a transparent material, while the central layer 32 is made of a light-opaque material.
Con el fin de integrar los medios de revelacion 28 en el cuerpo de tarjeta 12, al menos la capa central 32 del apilamiento comprende, por ejemplo, una cavidad 36 de recepcion de la ventana 30. La ventana 30 tiene una forma general oval en esta figura 2, pero puede tener igualmente una forma general rectangular como en la figura 1.In order to integrate the revealing means 28 into the card body 12, at least the central layer 32 of the stack comprises, for example, a reception cavity 36 of the window 30. The window 30 has a general oval shape in this Figure 2, but it can also have a general rectangular shape as in Figure 1.
Por ejemplo, la ventana 30 esta montada ajustada en la cavidad 36, es decir, que el contorno de la cavidad corresponde sustancialmente al contorno de la ventana de manera que durante la insercion de la ventana en la cavidad, las fuerzas de rozamientos ejercidas de las paredes de la cavidad sobre las de la ventana permiten el mantenimiento en su lugar de la ventana en esta posicion mediante friccion en el transcurso del procedimiento.For example, the window 30 is mounted adjusted in the cavity 36, that is to say that the contour of the cavity corresponds substantially to the contour of the window so that during the insertion of the window into the cavity, the frictional forces exerted from the Cavity walls over those of the window allow the window to be maintained in this position by friction in the course of the procedure.
Ademas, preferentemente, la antena 26 formada por una pluralidad de espiras se extiende segun una trayectoria sobre el cuerpo de tarjeta 12 y los medios de revelacion 28 estan dispuestos fuera de la trayectoria de las espiras de la antena.Also, preferably, the antenna 26 formed by a plurality of turns extends according to a path on the card body 12 and the revealing means 28 are arranged outside the path of the turns of the antenna.
A continuacion, las capas 32, 34 se ensamblan entre sf mediante aplicacion de un ciclo de laminacion. Al final de este ciclo, las capas estan solidarizadas entre sf y la ventana 30 esta perfectamente integrada en el conjunto.Next, the layers 32, 34 are assembled together by applying a rolling cycle. At the end of this cycle, the layers are in solidarity with each other and the window 30 is perfectly integrated into the set.

Por supuesto, como se describe esto, la ventana 30 no permite revelar la informacion oculta 20 en los datos 14 de la misma tarjeta. De hecho, la relativa rigidez del cuerpo de tarjeta 12 impide cualquier deformacion suficiente de esta ultima para permitir una puesta en coincidencia de la ventana 30 y de la informacion oculta 20 de una misma tarjeta.Of course, as this is described, the window 30 does not allow to reveal the hidden information 20 in the data 14 of the same card. In fact, the relative stiffness of the card body 12 prevents any sufficient deformation of the latter to allow a matching of the window 30 and the hidden information 20 of the same card.
Finalmente, los datos 14 se imprimen con unos medios convencionales como una impresion offset, una impresion mediante grabado laser, etc. En el caso de un grabado laser, los datos se inscriben, por ejemplo, mediante el ennegrecimiento del material sensible al laser que compone el cuerpo de tarjeta.Finally, data 14 is printed with conventional means such as offset printing, laser engraving, etc. In the case of a laser engraving, the data is entered, for example, by the blackening of the laser-sensitive material that makes up the card body.
La informacion esta codificada segun un tipo predefinido de codificacion. De esta manera, la informacion oculta con esteganograffa esta codificada segun una tecnica de interferencia predefinida.The information is coded according to a predefined type of coding. In this way, the information hidden with steganography is coded according to a predefined interference technique.
En una primera variante, la informacion puede comprender un elemento polarizado, es decir, que comprende una direccion de observacion privilegiada y los medios de revelacion de esta informacion comprenden un elemento optico, como un filtro polarizado, que comprende una direccion de polarizacion privilegiada.In a first variant, the information may comprise a polarized element, that is, comprising a privileged observation address and the disclosure means of this information comprise an optical element, such as a polarized filter, which comprises a privileged polarization direction.
En una segunda variante, la informacion esta coloreada con una tinta de un color predefinido y los medios deIn a second variant, the information is colored with an ink of a predefined color and the means of

Ahora, van a describirse los principales aspectos de un procedimiento de verificacion de la autenticidad del documento de seguridad segun la invencion como se representa en la figura 1.Now, the main aspects of a procedure for verifying the authenticity of the security document according to the invention as depicted in Figure 1 will be described.
En la figura 3, se han representado unos documentos de seguridad primero 10A y segundo 10B, por ejemplo, unas tarjetas de identidad, que pertenecen cada uno respectivamente a unos portadores primero y segundo.In FIG. 3, first 10A and second 10B security documents have been represented, for example, identity cards, each respectively belonging to first and second carriers.
En la continuacion de la descripcion, se anotaran con un mdice A, las referencias numericas que designan losIn the continuation of the description, the numerical references that designate the
elementos del documento de seguridad 10A y con un mdice B, las referencias numericas que designan loselements of security document 10A and with an index B, the numerical references that designate the
elementos del documento de seguridad 10B.elements of security document 10B.
En este ejemplo ilustrado, los datos que llevan cada una de las tarjetas son unos datos personales relacionados con la identidad de su portador. Los datos personales comprenden, en concreto, una fotograffa y unos datos que se refieren a los apellidos y nombres, asf como a una fecha de nacimiento.In this illustrated example, the data carried by each of the cards are personal data related to the identity of its carrier. Personal data includes, in particular, a photograph and data that refer to last names and names, as well as a date of birth.
Con el fin de autentificar, por ejemplo, el primer documento de seguridad 10A, es suficiente con superponer el segundo documento de seguridad 10B de manera que los medios de revelacion 28B de este documento 10B coincidan sustancialmente con la posicion de la informacion oculta 20A presente en el primer documento 10A.In order to authenticate, for example, the first security document 10A, it is sufficient to superimpose the second security document 10B so that the disclosure means 28B of this document 10B substantially coincides with the position of the hidden information 20A present in the first document 10A.
De esta manera, como es visible esto en la figura 3, la informacion oculta 20A inicialmente aparece y se vuelve perceptible.Thus, as this is visible in Figure 3, the hidden information 20A initially appears and becomes noticeable.
Gracias a la invencion, es posible autentificar de manera rapida y sin necesitar herramientas complejas un documento de seguridad en forma de tarjeta ngida, incluso seminigida. Un documento de este tipo constituye una seguridad de primer nivel particularmente fiable y de utilizacion sencilla.Thanks to the invention, it is possible to authenticate quickly and without the need for complex tools a security document in the form of a nigged card, even semi-transmitted. Such a document constitutes a first level security that is particularly reliable and easy to use.
