Abstract

The document e.g. identity card (20), has identification information i.e. personalization information, presented in the form of an inversed or negative image (12') i.e. photograph, of another identification information that is presented in the form of positive image (12). The images are printed on a surface of the document, in a side by side manner. The images are formed on an inner surface of a document constitution layer such that the information are invisible to an eye, where the layer is made of polycarbonate comprising carbon particles. An independent claim is also included for a method of securing an identification document.

Description

La présente invention concerne la sécurité des supports d'information ou données. Plus particulièrement, l'invention concerne la sécurisation des supports d'information afin que les informations d'identification notamment ne soient pas altérées ou modifiées, et que les supports ne soient pas ainsi réutilisés frauduleusement.The present invention relates to the security of information carriers or data. More particularly, the invention relates to securing information media so that identification information in particular is not altered or modified, and that the media are not thus fraudulently reused.

L'invention se situe dans le domaine des documents d'identification à puce ou sans puce, tel que des permis de conduire, des cartes d'identité, des cartes de membre, des badges d'accès, des passeports, des cartes bancaires, des porte-monnaie électroniques, des cartes multi-application et autres papiers de valeurs. Du fait de la valeur et de l'importance associée à chacun de ces documents, ils font souvent l'objet de copies non autorisées, d'altérations, de modifications, et contrefaçons.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.

Ainsi, par exemple, les impressions au moyen d'un laser ne permettent pas d'empêcher l'ajout d'information. Un tel ajout d'information peut par exemple conduire à changer complètement une photographie en rajoutant plus de cheveux ou une moustache ou des lunettes etc... Un exemple de falsification de photographie par ajout de zones noircies au moyen d'un faisceau laser est illustré sur la figure 1. Sur la carte 10 originale, des informations concernant l'identité du titulaire sont inscrites dans une zone de texte 11, et une photographie 12 du titulaire est imprimée par exemple par gravure au laser de la surface de la carte. Cette photographie étant imprimée dans l'épaisseur de la carte par gravure au laser, elle est indélébile et les zones noircies ne peuvent pas être enlevées. En revanche, il est possible de rajouter des zones noircies par exemple dans la zone de texte 11 pour modifier l'identité du titulaire, mais aussi sur la photographie 12 pour modifier la physionomie du titulaire. Dans l'exemple de la figure 1, la photographie originale 12 de la carte 10 est modifiée, des cheveux sont ajoutés au moyen d'un faisceau laser et des zones d'ombre sont rajoutées pour accentuer les pommettes et le teint de la peau, de sorte qu'une nouvelle photographie falsifiée 12A est réalisée sur la carte 10A.For example, laser printing does not prevent the addition of information. Such an addition of information may, for example, lead to completely changing a photograph by adding more hair or a mustache or glasses, etc. An example of falsification of photography by adding blackened areas by means of a laser beam is illustrated. on the figure 1 . On the original card 10, information concerning the identity of the holder is written in a text box 11, and a photograph 12 of the holder is printed for example by laser engraving of the surface of the card. This photograph being printed in the thickness of the card by laser engraving, it is indelible and the blackened areas can not be removed. On the other hand, it is possible to add blackened areas for example in the text box 11 to change the identity of the holder, but also on the photograph 12 to change the face of the holder. In the example of the figure 1 , the original photograph 12 of the map 10 is modified, hair is added by means of a laser beam and shaded areas are added to accentuate the cheekbones and the complexion of the skin, so that a new falsified photograph 12A is performed on the map 10A.

Pour éviter que de telles fraudes soient réalisées sur les documents d'identification, différents types de moyens de sécurisation sont utilisés. Une solution consiste à superposer des lignes ou guilloches sur une image d'identification, de type photographie. Ainsi, si une impression ultérieure est réalisée, les guilloches apparaissent en blanc sur le fond noir rajouté. D'autres solutions consistent à ajouter des éléments de sécurité de type hologrammes, informations imprimées avec une encre réagissant aux rayonnements ultra-violets, des micro-lettres cachées dans une image ou un texte etc...To prevent such frauds being made on the identification documents, different types of security means are used. One solution consists in superimposing lines or guilloches on an identification image, of the photographic type. Thus, if a subsequent impression is made, the guilloches appear in white on the added black background. Other solutions consist in adding security elements of the hologram type, information printed with an ink reacting to ultraviolet radiation, hidden micro-letters in an image or text, etc.

Ces solutions permettent une bonne sécurisation des supports d'information mais elles nécessitent du matériel et/ou des équipements supplémentaires engendrant des surcoûts de production.These solutions make it possible to securely secure the information media but they require additional equipment and / or equipment generating additional production costs.

Aussi, le problème technique objet de la présente invention consiste à proposer un document d'identification sécurisé comprenant une première information d'identification, qui consisterait en une solution alternative aux solutions existantes, simple à mettre en oeuvre et permettant de réduire les coûts de production.Also, the technical problem of the present invention is to provide a secure identification document comprising a first identification information, which would consist of an alternative solution to existing solutions, simple to implement and to reduce production costs. .

La solution au problème technique posé est obtenue, selon la présente invention par le fait que le document d'identification sécurisé comprend une deuxième information d'identification se présentant sous la forme d'une image inversée de la première information d'identification.The solution to the technical problem posed is obtained, according to the present invention, by the fact that the secure identification document comprises a second piece of identification information in the form an inverted image of the first identification information.

Ainsi, le fait de disposer à la fois d'une information sous forme d'image positive et d'une information sous forme d'image inversée, c'est-à-dire sous forme d'image négative, sur le même document d'identification, permet de comparer les deux images et de voir très rapidement s'il y a eu falsification. En effet, s'il est très facile de rajouter des zones noircies sur une image imprimée en positif pour la modifier, il est en revanche beaucoup plus difficile de le faire sur l'image inversée, car cela revient à rajouter des zones de couleur complémentaire. Prenons l'exemple de la gravure laser illustrée sur la figure 1 qui est une technique destructive ; s'il est possible de graver le positif pour rajouter des cheveux noirs, il n'est en revanche pas possible de rajouter ces mêmes parties sur le négatif puisque cela revient à rajouter du blanc, la couleur complémentaire. Le rajout de blanc sur le négatif est impossible car, l'impression du négatif étant réalisée par gravure laser, cela reviendrait à enlever les zones préalablement gravées qui apparaissent en noir.Thus, the fact of having both information in the form of a positive image and information in the form of an inverted image, that is to say in the form of a negative image, on the same document identification, makes it possible to compare the two images and to see very quickly if there has been falsification. Indeed, if it is very easy to add blackened areas on a printed image in positive to modify it, it is on the other hand much more difficult to do it on the inverted image, because it amounts to adding complementary color zones . Let's take the example of laser engraving illustrated on the figure 1 which is a destructive technique; if it is possible to engrave the positive to add black hair, it is however not possible to add these same parts on the negative since it amounts to adding white, the complementary color. The addition of white on the negative is impossible because, the printing of the negative being done by laser engraving, it would be like removing the previously engraved areas that appear in black.

Dans un autre mode de réalisation où l'impression est réalisée par report, dans le corps du document, d'un support métallique obtenu par gravure d'une plaque métallique ou par pulvérisation d'encre métallique, il est également très difficile de rajouter des informations sur la première image et de retirer ces mêmes informations sur la deuxième image.In another embodiment where the printing is carried out by transferring, in the body of the document, a metal support obtained by etching a metal plate or by spraying metallic ink, it is also very difficult to add information on the first image and remove that same information on the second image.

L'invention porte également sur un procédé de fabrication d'un document d'identification sécurisé, comprenant une étape d'impression d'une première information d'identification, caractérisé en ce que pendant l'étape d'impression, une deuxième information d'identification, se présentant sous forme d'image inversée de la première information d'identification, est imprimée.The invention also relates to a method for manufacturing a secure identification document, comprising a step of printing a first identification information, characterized in that during the printing step, a second piece of information is identification, in the form of an image inverted from the first identification information, is printed.

Ainsi, les deux informations d'identification sont imprimées simultanément sous formes d'images inversées l'une par rapport à l'autre. La sécurisation ne requiert qu'une seule étape d'impression, ce qui est facile à réaliser, n'entraine pas l'utilisation de machines spéciales supplémentaires et n'engendre pas de surcoût.Thus, both identification information is printed simultaneously as inverted images with respect to each other. The security requires only one printing step, which is easy to perform, does not involve the use of additional special machines and does not generate additional cost.

L'invention porte également sur un lecteur de document d'identification sécurisé caractérisé en ce qu'il comprend au moins un moyen de lecture des deux informations d'identification, des moyens de traitement numériques des deux informations d'identification lues, et des moyens -de comparaison des deux informations d'identification lues et traitées. Le moyen de lecture peut se présenter sous la forme d'un moyen optique, de type scanner par exemple qui balaye la surface de la carte ou d'un moyen de lecture capacitif ou inductif lorsque l'information d'identification est imprimée sous forme d'un support métallique.The invention also relates to a secure identification document reader characterized in that it comprises at least one means for reading the two identification information, digital processing means for the two identification information read, and means for comparing the two identification information read and processed. The reading means may be in the form of an optical means, for example a scanner, which scans the surface of the card or a capacitive or inductive reading means when the identification information is printed in the form of a metal support.

Enfin, l'invention porte aussi sur une installation d'impression d'un document d'identification sécurisé, caractérisée en ce qu'elle comprend un dispositif de saisie d'une première information d'identification, un moyen de traitement d'image pour créer une information d'identification supplémentaire sous forme d'image inversée complémentaire de la première information d'identification, des moyens de pilotage d'au moins un moyen d'impression pour imprimer lesdites première et deuxième information d'identification.Finally, the invention also relates to a printing installation of a secure identification document, characterized in that it comprises a device for inputting a first identification information, an image processing means for creating additional identification information in the form of an inverted image complementary to the first identification information, means for controlling at least one printing means for printing said first and second identification information.

D'autres particularités et avantages de l'invention apparaîtront à la lecture de la description suivante faite à titre d'exemple illustratif et non limitatif, en référence aux figures annexées qui représentent :

  • la figure 1, déjà décrite, une carte d'identification supportant une photographie originale et une carte falsifiée supportant une photographie modifiée,
  • la figure 2, un schéma en vue de dessus d'un document d'identification sécurisé selon l'invention,
  • la figure 3, un schéma en vue de dessus d'un autre document d'identification sécurisé selon l'invention,
  • la figure 4, un schéma en coupe d'un document d'identification selon une variante de réalisation.
Other features and advantages of the invention will appear on reading the following description given by way of illustrative and non-limiting example, with reference to the appended figures which represent:
  • the figure 1 , already described, an identification card supporting an original photograph and a falsified card supporting a modified photograph,
  • the figure 2 , a diagram in top view of a secure identification document according to the invention,
  • the figure 3 , a diagram in top view of another secure identification document according to the invention,
  • the figure 4 , a sectional diagram of an identification document according to an alternative embodiment.

Les exemples décrits ci-dessous concernent des cartes d'identification sensiblement rigides, comme des cartes d'identité par exemple. Cependant, l'invention ne se limite pas à des cartes mais s'étend à toutes sortes d'objet d'identification avec ou sans puce, tel que des passeports ou autres papiers souples de valeur.The examples described below relate to substantially rigid identification cards, such as identity cards for example. However, the invention is not limited to cards but extends to all kinds of identification objects with or without a chip, such as passports or other valuable soft papers.

Sur les figures 1 à 3, sont représentées des cartes 10, 20, 30 ou badges portant des données de personnalisation 11. Les données de personnalisation 11 sont marquées sur la carte ou dans l'épaisseur de la carte. Ces données identifient le titulaire et sont donc personnelles à l'individu porteur régulier de cette carte. Une photographie 12 du titulaire de la carte peut également être imprimée à la surface de la carte.On the Figures 1 to 3 10, 20, 30 or badges carrying personalization data 11 are shown. The personalization data 11 are marked on the card or in the thickness of the card. These data identify the holder and are therefore personal to the individual regular bearer of this card. A photograph 12 of the cardholder may also be printed on the surface of the card.

La carte 20, 30 ainsi personnalisée et comprenant une zone 11 de texte et/ou une zone 12 photographique peut avoir été réalisée à partir d'un corps de carte relativement rigide sur les deux faces opposées duquel ont été placés un film de protection supérieur et un film de protection inférieur. Typiquement, l'assemblage de ces trois éléments est fait par laminage à chaud. Les films de protection servent principalement à protéger le corps de carte contre les agressions mécaniques extérieures. Ils sont typiquement transparents, souples et réalisés en plastique tel que du polychlorure de vinyl (PVC) ou du polycarbonate (PC).The card 20, 30 thus personalized and comprising a text zone 11 and / or a photographic zone 12 may have been made from a relatively rigid card body on the two opposite sides of which a superior protective film has been placed and a lower protective film. Typically, the assembly of these three elements is made by hot rolling. The protective films serve mainly to protect the card body against external mechanical aggression. They are typically transparent, flexible and made of plastic such as polyvinyl chloride (PVC) or polycarbonate (PC).

Préalablement à cela, le marquage 11 et 12 de personnalisation est réalisé sur l'une au moins des faces du corps de carte, par exemple par gravure au moyen d'un faisceau laser. Le marquage peut également être réalisé dans le matériau de constitution du corps de carte. Dans ce cas, la couche de constitution est par exemple du polycarbonate comprenant des particules de carbone pour pouvoir créer une image en noir et blanc au moyen d'un faisceau laser.Prior to this, the marking 11 and 12 customization is performed on at least one of the faces of the card body, for example by etching by means of a laser beam. The marking can also be carried out in the constitution material of the card body. In this case, the layer of constitution is for example polycarbonate comprising carbon particles to be able to create a black and white image by means of a laser beam.

Typiquement, le corps de carte peut être en PVC, en polycarbonate (PC) ou encore en polyéthylène téréphtalate (PET).Typically, the card body may be PVC, polycarbonate (PC) or polyethylene terephthalate (PET).

Pour sécuriser le document d'identification et éviter toute modification et/ou altération des données de personnalisation, au moins une des informations de personnalisation, par exemple la photographie 12 sur la figure 2, est dupliquée en image inversée 12'. Ainsi, la carte supporte non seulement la photographie en positif 12 du titulaire de la carte, mais également la photographie en négatif 12' du titulaire de la carte. Les deux images 12, 12' inversées étant placées côte à côte, elles peuvent être facilement comparées à l'oeil nu ou au moyen d'un dispositif de lecture comprenant par exemple un moyen de lecture optique qui scanne les images, un moyen de traitement des images lues et un moyen de comparaison des deux images lues et traitées.To secure the identification document and avoid any modification and / or alteration of the personalization data, at least one of the personalization information, for example the photograph 12 on the figure 2 , is duplicated in inverted image 12 '. Thus, the card supports not only the positive photo 12 of the card holder, but also the negative 12 'photograph of the card holder. The two images 12, 12 'inverted being placed side by side, they can be easily compared with the naked eye or by means of a reading device comprising for example an optical reading means which scans the images, a means of treatment read images and a means for comparing the two images read and processed.

Dans l'exemple illustré sur la figure 2, seule la photographie 12 est dupliquée en image inversée, mais bien sûr l'invention permet de dupliquer n'importe qu'elle zone d'information en image inversée, que ce soit une zone d'image 12 ou une zone de texte 11.In the example shown on the figure 2 , only the photograph 12 is duplicated in reverse image, but of course the invention makes it possible to duplicate any information zone in inverted image, whether it is an image zone 12 or a text zone 11.

Ainsi, la présence de l'image en négatif 12' permet de visualiser de manière instantanée, par simple comparaison, si l'image en positif 12 a été modifiée par ajout d'éléments. En effet, s'il est possible de rajouter des cheveux par exemple en gravant au laser la surface de la carte dans l'image 12, il n'est en revanche pas possible de rajouter la couleur complémentaire blanche dans l'image inversée 12' car cela reviendrait à effacer du noir obtenu préalablement par gravure de la surface de la carte.Thus, the presence of the negative image 12 'makes it possible to instantaneously display, by simple comparison, whether the positive image 12 has been modified by adding elements. Indeed, if it is possible to add hair for example by laser engraving the surface of the card in the image 12, it is however not possible to add the complementary white color in the inverted image 12 'as it would be to erase the black previously obtained by engraving the surface of the map.

Dans une variante de réalisation, il est également possible de réaliser l'image inversée 12" en plus petit format que le positif. Il est également possible de l'incruster dans un coin prédéterminé de l'image positive 12 tel que cela est représenté sur la figure 3.In an alternative embodiment, it is also possible to make the inverted image 12 "in smaller than the positive format.It is also possible to embed it in a predetermined corner of the positive image 12 as shown on the figure 3 .

Dans ce cas, il est préférable d'avoir un dispositif de lecture pour effectuer la comparaison des deux images car si les modifications sont légères elles ne seront pas forcément visibles à l'oeil nu sur le négatif 12" de plus petit format. Un moyen de lecture optique de type scanner lit les deux images, un moyen de traitement les traite numériquement, puis un moyen de comparaison les compare. Dans le cas où le moyen de comparaison détecte une différence entre les deux images analysées, il transmet par exemple un signal d'alerte visuel et/ou sonore.In this case, it is preferable to have a reading device to perform the comparison of the two images because if the modifications are slight they will not necessarily be visible to the naked eye on the negative 12 "of smaller size. scanner reads the two images, a processing means processes them numerically, and a comparison means compares them.In the case where the comparison means detects a difference between the two analyzed images, it transmits for example a signal visual and / or audible warning.

Le procédé de sécurisation du document d'identification est de préférence réalisé en une seule étape d'impression, au moyen d'une installation d'impression. Cette installation d'impression comporte par exemple un dispositif de saisie d'information tels que par exemple un dispositif de prise de vue pour une photographie ou un clavier pour saisir du texte etc. Un moyen de traitement d'image permet ensuite de créer une image supplémentaire inversée, complémentaire de la première information saisie, puis des moyens de pilotage permettent de commander au moins un moyen d'impression pour imprimer l'image positive 12 et l'image inversée 12', 12" sur la surface de la carte, et/ou dans une couche de constitution de la carte. Ce moyen d'impression est par exemple un faisceau laser. Lorsque l'impression se fait à la surface de la carte, elle se fait par gravure à l'aide du faisceau laser. Lorsque l'impression se fait dans une couche de constitution de la carte au moyen du faisceau laser, la couche de constitution est par exemple du polycarbonate comprenant des particules de carbone qui réagissent lorsqu'elles sont est éclairées par le faisceau laser, de sorte qu'une image en noir et blanc est créée.The method of securing the identification document is preferably carried out in a single printing step, by means of a printing installation. This printing installation comprises for example an information input device such as for example a shooting device for a photograph or a keyboard for entering text etc. An image processing means then makes it possible to create an additional inverted image, complementary to the first information input, and then control means for controlling at least one printing means for printing the positive image 12 and the inverted image. 12 ', 12 "on the surface of the card, and / or in a layer of constitution of the card. example a laser beam. When the impression is made on the surface of the card, it is done by engraving using the laser beam. When the printing is done in a layer of constitution of the card by means of the laser beam, the layer of constitution is for example polycarbonate comprising carbon particles which react when they are illuminated by the laser beam, so that a black and white image is created.

Dans une variante de réalisation, au moins l'une des informations d'identification 12, 12' ou 12" est réalisée par report d'un support métallique gravé ou pulvérisé. Dans ce cas, un autre moyen d'impression consiste en un moyen de report d'un support métallique obtenu par gravure ou en un moyen de pulvérisation de métal ou d'encre métallique.In an alternative embodiment, at least one of the identification information 12, 12 'or 12 "is produced by transfer of an engraved or pulverized metal support, in which case another printing means consists of a means transferring a metal support obtained by etching or a means for spraying metal or metal ink.

Dans ce cas, le dispositif de lecture doit en outre comprendre un moyen de lecture de type capacitif ou inductif.In this case, the reading device must further comprise capacitive or inductive reading means.

Lorsque les deux informations d'identification inversées sont réalisées selon cette variante, elles peuvent toutes deux être imprimées soit à la surface de la carte, soit sur la surface d'une des couches de constitution de la carte, soit à la surface de deux couches différentes comme illustré sur la figure 4. Ainsi, par exemple lorsqu'elles sont imprimées à la surface de la carte, l'oeil du contrôleur permet de réaliser un premier contrôle visuel avant d'insérer le document dans un lecteur, comprenant un moyen de lecture capacitif ou inductif, pour un contrôle plus approfondi.When the two reverse identification information is produced according to this variant, they can both be printed either on the surface of the card, or on the surface of one of the layers of constitution of the card, or on the surface of two layers different as illustrated on the figure 4 . Thus, for example when they are printed on the surface of the card, the eye of the controller makes it possible to carry out a first visual check before inserting the document in a reader, comprising a capacitive or inductive reading means, for a control more in depth.

Lorsqu'elles sont imprimées à la surface d'une couche de constitution de la carte et qu'elles sont recouvertes par une couche opaque, elles ne sont plus visibles à l'oeil nu, et seul un moyen de lecture capacitif ou inductif permet de les scanner avant de les traiter et de les comparer.When they are printed on the surface of a layer of constitution of the card and they are covered by an opaque layer, they are no longer visible to the naked eye, and only a capacitive or inductive reading means makes it possible to scan them before treating and comparing them.

Dans l'autre cas, tel qu'illustré sur la figure 4, la première information d'identification 48 est imprimée à la surface de la carte 40 et la deuxième information d'identification 49 est imprimée à la surface d'une 43 des couches de constitution 41, 42, 43, 44, 45 de la carte 40. Dans ce cas, la première information 48 reste visible, tandis que la deuxième information est invisible si bien qu'un fraudeur qui tente de modifier la première information ne pourra pas non plus modifier la deuxième information. Un moyen de lecture capacitif ou inductif permet de lire chaque information avant de les traiter et de les comparer.In the other case, as shown on the figure 4 the first identification information 48 is printed on the surface of the card 40 and the second identification information 49 is printed on the surface of a 43 of the constituent layers 41, 42, 43, 44, 45 of the card 40. In this case, the first piece of information 48 remains visible, while the second piece of information is invisible, so that a fraudster who tries to modify the first piece of information will not be able to modify the second piece of information either. Capacitive or inductive reading means makes it possible to read each piece of information before processing and comparing them.

Dans une autre variante de réalisation, la première information 48 peut être imprimée au moyen d'un faisceau laser à la surface de la carte 40, tandis que la deuxième information 49 est réalisée par report ou pulvérisation métallique à la surface d'une couche de constitution 43 de la carte. Dans ce cas, l'installation d'impression comprend un moyen d'impression laser ainsi qu'un moyen de report d'un support métallique gravé ou de pulvérisation de métal ou d'encre métallique. De même, le dispositif de lecture comprend un moyen de lecture optique de type scanner et un moyen de lecture capacitif ou inductif. Une fois chaque information lue à l'aide du moyen de lecture qui leur est approprié, elles sont traitées numériquement puis comparées à l'aide d'un moyen de comparaison. Lorsque le moyen de comparaison détecte des différences entre les deux informations, il envoie un message d'alerte sonore et/ou visuel, de sorte que l'agent contrôleur soit alerté de la fraude.In another variant embodiment, the first piece of information 48 can be printed by means of a laser beam on the surface of the card 40, while the second piece of information 49 is made by transfer or metal spraying on the surface of a layer of constitution 43 of the card. In this case, the printing installation comprises a laser printing means as well as a means for transferring an etched metal support or for spraying metal or metal ink. Similarly, the reading device comprises scanner-type optical reading means and capacitive or inductive reading means. Once each information read using the reading means that is appropriate, they are processed numerically and compared using a means of comparison. When the means of comparison detects differences between the two pieces of information, it sends an audible and / or visual warning message so that the controller is alerted to the fraud.
