Description Description

La présente invention a pour objet une carte informatique et un procédé pour sa fabrication. The present invention relates to a computer card and a method for its manufacture.

L'un des problèmes majeurs que posent les cartes informatiques est dû au risque d'un emploi illégal ou simplement abusif de celles-ci par des gens non habilités à en faire usage. One of the major problems posed by computer cards is due to the risk of illegal or simply improper use of them by people who are not authorized to use them.

Différents moyens d'identification des titulaires de telles cartes ont été proposés pour empêcher leur emploi non autorisé, mais ils ne donnent pas entière satisfaction: soit ils sont peu sûrs et peuvent être violés par ceux qui connaissent leur principe opérationnel, soit ils sont plus sophistiqués mais alors ils renchérissent par trop le coût de la carte. Il faut en effet tenir compte du fait que ces cartes sont différentes d'un groupe d'utilisateurs à l'autre et qu'elles ne peuvent généralement pas, de ce fait même, être réalisées entièrement en série, c'est-à-dire jusqu'à et y compris l'adjonction des moyens d'identification de leur futur groupe d'utilisateurs (banque, chaîne commerciale ou autre). Various means of identifying the holders of such cards have been proposed to prevent their unauthorized use, but they are not entirely satisfactory: either they are insecure and can be violated by those who know their operational principle, or they are more sophisticated but then they add too much to the cost of the card. It must indeed be taken into account that these cards are different from one group of users to another and that they cannot generally, by this very fact, be produced entirely in series, that is to say say up to and including the addition of the means of identification of their future group of users (bank, commercial chain or other).

Le but de la présente invention est de remédier à ces inconvénients en fournissant une carte informatique qui soit aisément et sans frais appréciables munie de moyens de sécurité pratiquement inviolables ainsi qu'un procédé pour sa fabrication à la fois simple et peu coûteux. The object of the present invention is to remedy these drawbacks by providing a computer card which is easily and without appreciable cost provided with practically inviolable security means as well as a method for its manufacture which is both simple and inexpensive.

Ce but est atteint grâce aux moyens définis dans les revendications 1 et 8. This object is achieved by the means defined in claims 1 and 8.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. The drawing represents, by way of example, an embodiment of the subject of the invention.

La fig. 1 est une vue en plan d'une carte informatique, et Fig. 1 is a plan view of a computer card, and

La fig. 2 en est une coupe, suivant la ligne ll-ll de la fig. 1, à échelle fortement agrandie. Fig. 2 is a section thereof, along the line II-II of FIG. 1, on a greatly enlarged scale.

La carte informatique représentée comprend un substrat en matière plastique 1 présentant, dans son épaisseur, une creusure 2 dont le fond est en relief en 3. The computer card shown comprises a plastic substrate 1 having, in its thickness, a recess 2, the bottom of which is in relief in 3.

La conformation du relief 3 fournit les données relatives à l'identité de l'utilisateur de la carte. Ainsi, chaque carte présentera un relief du fond de sa creusure qui sera différent. Ce relief pourra soit former un motif, soit être constitué de surfaces convexes, comme dans l'exemple représenté, et/ou concaves intersectées. Le fait que ce relief soit situé au fond d'une creusure de la carte le protège de l'usure et rend inutile qu'il soit revêtu d'un film protecteur qui pourrait fausser les informations qu'il fournit, d'autant que les différences de hauteurs de ce relief seront très faibles, de l'ordre de quelques centièmes de mm. The configuration of the relief 3 provides the data relating to the identity of the user of the card. Thus, each card will present a relief of the bottom of its hollow which will be different. This relief can either form a pattern, or consist of convex surfaces, as in the example shown, and / or intersecting concaves. The fact that this relief is located at the bottom of a recess in the card protects it from wear and makes it unnecessary for it to be coated with a protective film which could distort the information it provides, especially since the differences in height of this relief will be very small, of the order of a few hundredths of a mm.

La carte représentée sera utilisée sur un appareil de détection travaillant sur trois axes de coordonnées qui sera muni de moyens d'exploration, de préférence électro-optiques, du fond de la creusure 2. The card shown will be used on a detection device working on three coordinate axes which will be provided with means of exploration, preferably electro-optical, of the bottom of the recess 2.

La carte informatique de l'exemple représenté est à module électronique, ce dernier étant indiqué en 4 à la fig. 1. Ce module électronique pourra être agencé de façon à fournir à l'appareil de détection du relief 3 des informations quant aux coordonnées des points où devront s'effectuer les contrôles. Ainsi, dans ce cas particulier de cartes à modules électroniques, plusieurs cartes pourront-elles présenter le même relief 3, la personnalisation de la carte s'ob-tenant par la diversité des points de contrôle. The computer card of the example shown is with electronic module, the latter being indicated at 4 in FIG. 1. This electronic module may be arranged so as to provide the relief detection device 3 with information as to the coordinates of the points where the checks will have to be carried out. Thus, in this particular case of cards with electronic modules, can several cards have the same relief 3, the personalization of the card being obtained by the diversity of control points.

Il est à remarquer que le module électronique pourra être scellé sur le substrat de la carte, la matière - plastique - du scellement présentant un relief qui permettra à un appareil de détection de vérifier que ledit module n'a subi aucune manipulation illicite. It should be noted that the electronic module may be sealed on the substrate of the card, the material - plastic - of the seal having a relief which will allow a detection device to verify that said module has not undergone any illicit manipulation.

La présente carte pourra être obtenue très aisément par moulage de son substrat 1. Une des parois du moule présentera une saillie dont la face antérieure présentera le relief inversé de celui du fond de la creusure de la carte à réaliser, laquelle creusure sera réalisée par ladite saillie. This card can be obtained very easily by molding its substrate 1. One of the walls of the mold will have a projection, the front face of which will have the relief reversed from that of the bottom of the recess of the card to be produced, which recess will be produced by said protrusion.

Cette saillie pourra se présenter sous la forme d'une pièce d'insertion se montant de façon amovible sur une des parois du moule, ce qui permettra de la remplacer aisément par une autre. This projection may be in the form of an insert which is removably mounted on one of the walls of the mold, which will allow it to be easily replaced by another.

La réalisation de la pièce d'insertion pourra se faire par tous moyens connus tels que photogravure ou autre. On pourra même l'obtenir par usinage mécanique, surtout lorsque le relief est formé de surfaces de révolution intersectées, qui varieront en faisant tourner la pièce en travail, pendant l'usinage, autour d'axes différents. The insertion piece can be produced by any known means such as photoengraving or the like. It can even be obtained by mechanical machining, especially when the relief is formed of intersected surfaces of revolution, which will vary by rotating the workpiece, during machining, around different axes.

Il est à remarquer que le relief du fond de la creusure de la présente carte pourra être constitué par une microstructure, par exemple un stéréogramme, ou, un hologramme dont les différences de hauteurs seront de l'ordre du millième de mm, et qui pourra y être apposée au moment même du moulage. It should be noted that the relief of the bottom of the recess of the present map may be constituted by a microstructure, for example a stereogram, or, a hologram whose differences in height will be of the order of a thousandth of a mm, and which may be affixed to it at the time of molding.

Une telle microstructure pourra également être acoustique et non pas optique, ou encore opto-élec-tronique. Such a microstructure can also be acoustic and not optical, or optoelectronic.

Le nombre considérable des différents reliefs qui pourront être mis en œuvre, de même que celui des différentes combinaisons des points où pourront s'effectuer les contrôles, rend la présente carte pratiquement inviolable. The considerable number of different reliefs that can be implemented, as well as that of the different combinations of points where checks can be carried out, makes this card practically inviolable.

La «lecture» de la microstructure que présente la carte pourra également s'effectuer en inscrivant sur celle-ci un texte ou un motif par projection d'encre. Si la surface sur laquelle est effectuée cette projection ne correspond pas à la surface pour laquelle l'appareil de projection aura été réglé, le texte ou le motif inscrit sur la carte sera distordu, ce qui permettra de déceler que la carte utilisée n'est pas la carte attendue. Pour rendre le motif conforme à l'original, sur une carte qui n'est pas la bonne, il faudrait modifier électroniquement la diffraction de la trajectoire des gouttes d'encre, ce qui ne peut se faire qu'en connaissant la fonction mathématique à l'aide de laquelle la microstructure a été réalisée. Ainsi, toute fraude est pratiquement impossible. The “reading” of the microstructure presented by the card can also be done by writing on it a text or a pattern by spraying ink. If the surface on which this projection is carried out does not correspond to the surface for which the projection device will have been set, the text or pattern written on the card will be distorted, which will make it possible to detect that the card used is not not the expected card. To make the pattern conform to the original, on a map that is not the right one, it would be necessary to electronically modify the diffraction of the trajectory of the ink drops, which can only be done by knowing the mathematical function to using which the microstructure was produced. Thus, any fraud is practically impossible.

Bien entendu la partie en relief de la carte pourra également fournir des informations autres que des informations d'identité. Of course, the raised part of the card can also provide information other than identity information.
