Definitions

  • the present invention relates to a customizable support comprising anti-forgery means provided to highlight any fraudulent personalization attempt, and a method of manufacturing such a support.
  • the invention lies in the field of identification documents chip or without chip, such as driving licenses, identity cards, membership cards, access badges, passports, bank cards, electronic purses, multi-application cards and other valuable papers. Because of the value and importance associated with each of these documents, they are often subject to unauthorized copies, alterations, modifications, and counterfeits.
  • the invention aims more particularly at securing personalization information written on the medium, so as to avoid any subsequent fraudulent modification of this information.
  • a customizable support for example an identity card, comprising a body 2 provided, on a top face 3, personalization information 4, 6, 7 official relating to the card holder.
  • This personalization information is reported via a graphical personalization means, for example YAG laser type.
  • the card 1 comprises a card body 2, made of an opaque plastic material, for example of the polycarbonate, PET and / or ABS or PVC type.
  • a transparent protective layer 5, also called “overlay" in the jargon of the cards, is advantageously fixed on at least one face of the card body.
  • the card body 2 is designed to be provided on its upper face 3 with personalization information 4.
  • the personalization information 4 shown on the card body 2 comprises, with reference to the figure 2 , the photographic representation 6 of the holder of the card and alphanumeric characters 7 relating to the identity of the holder.
  • the personalization data 7 and the photograph 6 are, for example, written on the surface 3 of the card body by means of a laser beam, by burning the surface of the card body. The local discoloration of the resulting surface depends on the available energy, the inscription time as well as the material of the card body used.
  • the personalization can be done directly in the transparent protective layer 5.
  • the material used for the transparent protective layer 5 is a material doped with carbon particles which darken under the action of a laser beam.
  • Another solution for securing personalized supports consists in forming anti-forgery means by subdividing each pixel, from the surface of a support, into a matrix of N points.
  • the N dots have a different color density from each other to allow obtaining an average color density of the matrix equivalent to a predetermined color density for the corresponding pixel.
  • At least some of the N points of the matrix are pre-sensitized to induce a more or less rapid darkening of their color in case of additional customization, compared to other non-pre-sensitized points.
  • the pre-sensitized points of each matrix undergoing this fraudulent additional personalization will react more or less than others and darken more or less quickly.
  • each matrix, or corresponding pixel will react differently and some pixels will appear darker or lighter than other surrounding pixels.
  • lines and / or texts and / or logos will appear in lighter shades and / or darker compared to an average color density, in areas where additional customization has been performed. Fraudulent personalization then appears immediately to the naked eye.
  • this solution is rather long and complex to implement, and therefore relatively expensive.
  • micro-perforations reproducing the personalization information, such as the photograph of the holder of the medium for example, so as to authenticate the photo of the holder.
  • a laser technology is used to create the micro-perforations through the thickness of the support body, the perforations being arranged to form an image that becomes clearly visible to the naked eye when the document is illuminated, thus allowing easy verification.
  • This technology requires an additional step of reproducing identically, and therefore very accurately, personalization information by laser perforation. Such a solution is however long and complex to implement, and therefore relatively expensive.
  • the technical problem which is the subject of the present invention consists in proposing a customizable support comprising a body provided, on one side, with personalization information, obtained by carbonization of the constitution material by means of a laser beam, and comprising means anti-forgery graphics, arranged on all or part of said personalization information, said anti-forgery graphics means being intended to highlight any attempt to fraudulently personalize said medium at said corresponding locations, which would make it possible to quickly highlight and simply any further fraudulent personalization attempts, which would also allow diversifying the means of anti-forgery for each medium, and finally would provide a serious and effective alternative to existing solutions already proposed.
  • the anti-forgery graphic means design a pattern and comprise, along this pattern, bubbles whose density varies as a function of the degree of carbonization of the particles. areas crossed by said pattern.
  • the invention also relates to a method for securing a customizable support comprising a body provided on one face with personalization information obtained by carbonization of the constituent material by means of a laser beam, characterized in that comprises a step of producing graphic anti-forgery means, on all or part of said personalization information, in a particular pattern so as to incorporate, along this pattern, bubbles whose density varies with the degree of carbonization the area traversed by the pattern, said anti-forgery graphics means being provided to highlight any attempt fraudulent personalization of said medium at said corresponding locations.
  • the invention also relates to a use of a CO 2 laser for securing personalization information on a customizable medium, said personalization information being made by carbonization of the constitution material of said customizable medium, by means of a YAG laser; said CO2 laser for generating the formation of bubbles in the carbonized zones, the density of said bubbles varying according to the degree of carbonization of the carbonized zone in which they are created.
  • FIGS. 3 and 4 illustrate a customizable support according to the invention.
  • the medium is represented in card format, but it is not limited to this format and can be in any other form, such as passport-type booklet for example.
  • the illustrated support comprises a body 2 protected from environmental constraints, on its two main faces, by a transparent protective layer 5, commonly called “overlay” in the jargon of the cards.
  • This medium includes personalization information in the form of alphanumeric characters 7 of the holder's identity and / or in the form of a photographic reproduction 6 of the holder of the medium.
  • Anti-forgery means 8 are also provided on at less certain areas of personalization information such as photography for example. These graphic means of anti-forgery draw a pattern 8 determined, such as a network of guilloches for example. This pattern 8 may also be variable or not from one medium to another.
  • the personalization information 6 is printed in the thickness of the overlay 5.
  • a laser-sensitive overlay is used.
  • This may be for example a polymer overlay loaded with carbon particles.
  • the polymer may be of PVC or polycarbonate type, for example.
  • a YAG laser at 1064 nm for example is used to carry out the official customization.
  • the carbon particles present inside the overlay absorb the energy of the YAG laser, and become black.
  • the internal structure of the overlay is then modified. Depending on the areas of the photograph to print, you burn more or less certain areas of the overlay that appear more or less blackened.
  • references 61 to 65 These areas are represented on the figure 4 , under references 61 to 65, where the reference 61 represents a very black zone and therefore with a high degree of carbonization of the carbon particles per unit volume, the reference 63 represents a gray zone comprising less carbonized particles per unit volume than the referenced area 61 etc.
  • the next step in the process of manufacturing a secure customizable support then consists in producing graphic anti-forgery means.
  • a CO 2 laser of wavelength equal to 10640 nm for example, is used. This laser makes it possible to draw a predetermined pattern and to allow the generation, along this pattern, of bubbles inside the overlay.
  • the higher the degree of carbonization per unit volume in the overlay the more this carbonized material is reactive to the CO 2 laser beam.
  • the CO 2 laser promotes a destruction of the material, so that it generates bubbles inside the overlay, whose density varies depending on the degree of carbonization per unit volume of the overlay .
  • the bubbles thus created can be of different nature. They may for example be filled with air, but they can also be filled with a gas resulting from the combustion of the material. Thus, they may for example be filled with a carbon dioxide that is formed due to the presence of carbon particles in the overlay, or a chlorine gas for example due to the combustion of PVC when this material is used for the realization of the overlay.
  • the figure 4 represents a detail of these anti-forgery means made on the support thus officially personalized.
  • the anti-forgery graphic means draw a pattern visible from the outside but not detrimental to the perception of the photograph 6.
  • This pattern referenced 90 on the detail of a photo 6 representing an eye on the figure 4 , represents for example a network of guilloches. It is advantageously made with a CO 2 laser. It allows you to create bubbles in the overlay. The density of bubbles depends on the degree of carbonization of the areas crossed by the pattern.
  • the density d1 of bubbles 9, generated in the highly charred zone 61 of the overlay is much higher than the density d3 of bubbles generated in the zone 63, which is itself higher than the density d5 of bubbles generated. in the area 65 very clear.
  • the bubbles thus generated although drawing a visible pattern from the change of the internal structure of the overlay, are transparent and do not disturb the visual perception of the photograph.
  • the bubble density also depends on the energy of the CO 2 laser used. It is important to properly regulate this energy so that it does not completely destroy the charred areas and the overlay and then affects the perception of photography. In fact, too much energy could lead to too much destruction of material that would make the perception of photography difficult or even impossible, and which would completely destroy the overlay. On the contrary, an energy too weak, would not create enough bubbles for an attempt to falsify can be detected.
  • the energy of the CO2 laser must therefore be adjusted to obtain the desired effect. However, the energy also depends on the laser used and in particular its focal length, its marking speed, its frequency, etc.
  • a guilloche pattern comprising bubbles generated with a density dependent on the degree of carbonization of the zones crossed, could be achieved inside a 150 ⁇ m thick overlay, with a CO2 laser on a contrast black and white image, with a power of 20W, a laser pulse frequency of 15KHz, and a marking speed of 1000 mm / s.
  • these values are only given by way of example, and it is within the abilities of those skilled in the art to master the settings of the laser used to obtain the desired optimum effects.
  • the figure 5 schematizes the case where an attempt at fraudulent personalization has been made on a photograph protected by the means of anti-forgery previously described.
  • the anti-forgery graphic means do not draw a pattern of guilloches as on the figure 4 but predetermined patterns 80 which are arranged at strategic locations of the photograph, that is, at vulnerable places and more subject to modification. These places are for example the hair, the eyes, the mouth, cheekbones etc ....
  • additional fraudulent personalization made YAG laser just like the official customization, is to add a charring overload, that is to say, to blacken certain areas.
  • Such fraudulent customization allows to add black on a photo, but it does not add bubbles on areas where overload has been added.
  • fraudulent personalization consists for example in browning the complexion of the holder of the photograph. Therefore, in areas 64 ', 65', where additional carbonization has occurred, the original density d4, d5 of bubbles 9 'remains and no longer matches the degree of carbonization. The overload is immediately visible to the naked eye because there are fewer bubbles in the dark areas added.
  • bubbles diverge and / or converge all or part of the YAG laser beam used by the fraudster, depending on the place of the beam with respect to the bubbles, so that a halot respectively lighter and / or darker around these bubbles and the anti-forgery pattern is created.
  • the fraudulent additional personalization therefore leaves traces and / or marks darker and / or lighter next to the security pattern, which then appears as a ghost image 81.
  • the fraudster wants to reconstruct the pattern drawn by the anti-forgery means, with the bubble density corresponding to the degree of carbonization of the falsified zones, he must determine the energy of the CO 2 laser used to create these bubbles.
  • obtaining an accurate density of bubbles is very difficult to control, especially since the higher the degree of carbonization, because the more bubbles are generated in the overlay the more risk there is. 'to damage the overlay and that it completely detaches from the card body.
  • An additional advantage of these bubbles created in the overlay lies in the fact that they make it possible to create zones of mechanical strength more or less reduced according to their density, so that in case of attempt to detach the overlay, that it rips along the patterns made by means of the CO 2 laser, containing more or fewer bubbles.
  • Another advantage of this preferred embodiment of the invention according to which the official personalization and anti-forgery patterns are created in the overlay lies in the fact that if a fraudster manages to remove the overlay completely, he It will be necessary to reconstruct not only a customization by means of a YAG laser, but also to have a CO2 laser to rebuild the bubbles. Assuming that this is possible, a variant of the invention is to extend the personalization and the generation of bubbles on the surface 3 of the body 2 of the support. In this case, the surface of the body of the support is burned by the YAG laser at the time of the official personalization, then it is engraved more or less deeply according to the degree of carbonization of the surface at the time of the step of securing by means of CO2 laser. Thus, the body 2 of the support and the overlay 5 are completely associated with each other and an attempt at delamination of the overlay would be immediately visible to the naked eye.
  • the density of bubbles depends on the blackened areas, so the bubble densities along the anti-falsification graphic pattern vary from one medium to another, depending on the holder's photograph. Moreover, although in the description, only anti-forgery means have been described in a photograph, they also apply to alphanumeric characters.
  • the reason that the graphic anti-forgery means draws may be different from one medium to another, the detection of the fraudulent customization not being done on the geometry of the pattern but on the density of bubbles associated with the degree of carbonization of the particles. crossed areas.
  • the anti-forgery graphic means that have just been described thus constitute a trace of official personalization, a trace that can not be modified in the event of additional fraudulent personalization.
