Description

Document sécurisé par une série de microperçages. Document secured by a series of microperforations.
La présente invention concerne un document sécurisé par une série de microperçages.The present invention relates to a document secured by a series of microperforations.
On connaît des procédés de sécurisation d'un document par une série de microperçages. En particulier, le document WO 97/18092 décrit un procédé consistant à réaliser des microperçages visibles par transparence et disposés selon un motif identifiable. Ce motif réalise une sécurité de niveau un, c'est-à-dire une sécurité qui peut être observée sans qu'il soit nécessaire d'utiliser un appareillage particulier. Dans ce document, la sécurité vient principalement du fait que les microperçages sont de dimensions suffisamment faibles pour ne pas être perceptibles lors d'un examen du document sous une lumière réfléchie. Cette sécurité est utile tant qu'un fraudeur n'est pas informé de l'existence des microperçages. Toutefois dès l'instant où un fraudeur est informé de cette existence, il est relativement aisé de reproduire le motif en utilisant une aiguille pour réaliser les microperçages . II est également connu du document WO 00/43216 un procédé consistant à réaliser des microperçages borgnes de profondeur plus ou moins importante ou des microperçages débouchant ayant des inclinaisons variées de sorte que le motif obtenu présente des tons de gris différents en fonction de l'épaisseur de matière traversée par la lumière lors d'une observation par transparence. Les différents tons de gris peuvent réaliser un encodage d'une information de sécurisation du document. Le motif obtenu peut donc être observé au moyen d'un appareillage adapté à analyser les différentes nuances de gris et effectuer un décodage du motif réalisé. Ce motif constitue donc une sécurité de niveau deux. En revanche les différentes nuances de gris peuvent difficilement être appréciées à l'œil nu de sorte qu'il sera possible pour un fraudeur de reproduire le motif avec des moyens qui n'auront certes pas une précision suffisante pour permettre une authenti- fication du document au niveau deux mais qui permettront néanmoins d'obtenir des différences de tons de gris suf- fisamment prononcés pour laisser croire qu'il s'agit d'un document authentique lors d'une analyse de niveau un.Methods for securing a document are known by a series of microperforations. In particular, document WO 97/18092 describes a method consisting in producing microperforations visible by transparency and arranged in an identifiable pattern. This pattern achieves level one security, that is, security that can be observed without the need to use special equipment. In this document, the security comes mainly from the fact that the microperforations are of sufficiently small dimensions not to be perceptible during an examination of the document under a reflected light. This security is useful as long as a fraudster is not informed of the existence of microperforations. However, from the moment a fraudster is informed of this existence, it is relatively easy to reproduce the pattern using a needle to carry out micro-drilling. It is also known from document WO 00/43216 a method consisting in producing blind microperforations of greater or lesser depth or microperforations opening out with varied inclinations so that the pattern obtained has different shades of gray depending on the thickness of matter through which the light passes during an observation by transparency. The different shades of gray can carry out an encoding of information for securing the document. The pattern obtained can therefore be observed by means of an apparatus suitable for analyzing the different shades of gray and performing a decoding of the pattern produced. This pattern therefore constitutes level two security. However, the different shades of gray can hardly be appreciated with the naked eye so that it will be possible for a fraudster to reproduce the pattern with means which will certainly not have sufficient precision to allow an authentication of the document at level two but which will nevertheless make it possible to obtain differences in shades of gray sufficiently pronounced to suggest that it is '' is an authentic document during a level one analysis.
Un but de l'invention est de proposer un moyen de sécurisation qui puisse servir de moyen d'authenti- fication à la fois lors d'une analyse de niveau un et lors d'une analyse de niveau deux.An object of the invention is to propose a security means which can serve as a means of authentication both during a level one analysis and during a level two analysis.
Selon l'invention, on prévoit un document sécurisé par une série de microperçages visibles par transparence, dans lequel la série de microperçages comprend des signes différents les uns des autres réalisant un enco- dage d'au moins une information de sécurisation du document .According to the invention, a document is provided which is secured by a series of microperforations visible by transparency, in which the series of microperforations comprises signs which are different from one another, encoding at least one item of information for securing the document.
Ainsi, lors d'une analyse de niveau un, on prend en compte la forme des signes et le document est authentifié si les signes ont une forme identique aux signes d'un document authentique, tandis que lors d'une analyse de niveau deux, les différences entre les signes sont prises en compte pour effectuer un décodage de l'information de sécurité et comparer celles-ci à une information authentique. Les microperçages ont de préférence une forme perceptible à l'œil nu. Ainsi, une simple observation par transparence permet d'effectuer l'analyse de niveau un.Thus, during a level one analysis, we take into account the form of the signs and the document is authenticated if the signs have a form identical to the signs of an authentic document, while during a level two analysis, the differences between the signs are taken into account in order to decode the security information and compare it with authentic information. The microperforations preferably have a shape that can be seen with the naked eye. Thus, a simple observation by transparency makes it possible to perform the level one analysis.
De préférence, les signes ont une forme présentant un contour complexe facilement identifiable. Les si- gnes ainsi réalisés sont alors difficiles à reproduire mais faciles à reconnaître, ce qui constitue un critère de qualité d'un moyen de sécurisation.Preferably, the signs have a shape with an easily identifiable complex outline. The signs thus produced are then difficult to reproduce but easy to recognize, which constitutes a quality criterion of a security means.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit de différents modes de réalisation de l'invention en référence aux figures 1 à 6 qui illustrent de façon schématique une partie d'un billet de banque ou un billet de banque comportant un mode de réalisation de l'invention. Sur chacune des figures les microperçages ont été représentés de façon très agrandie, le cas échéant hors de proportion avec les dimensions du billet de banque afin de mieux comprendre la caractéristique de l'invention illustrée par la figure. Sur chacune des fi- gures, les signes sont représentés par une impression noire bien qu'il s'agisse d'un perçage visible par transparence .Other characteristics and advantages of the invention will appear on reading the description which follows of different embodiments of the invention with reference to Figures 1 to 6 which schematically illustrate a part of a banknote or a banknote comprising an embodiment of the invention. In each of the figures, the micro-holes have been shown in a very enlarged manner, if necessary out of proportion with the dimensions of the bank note in order to better understand the characteristic of the invention illustrated by the figure. On each of the figures, the signs are represented by a black impression although it is a hole visible through transparency.
De façon connue en soi, les microperçages peuvent être réalisés soit dans le document lui-même, en particu- lier lorsque celui-ci est opaque, soit seulement dans les couches d'impression du document lorsque celui-ci est transparent, par exemple dans le cas d'un film en matière plastique transparente, soit encore dans un élément rapporté, tel qu'une pastille ou une bande, qui est ensuite fixée sur le document. Les microperçages selon l'invention peuvent même être non débouchants ou être recouverts par un film ou une pastille dès l'instant où l'épaisseur de matière fermant le microperçage est d'une transparence suffisante pour permettre une observation de la forme du microperçage par transparence.In a manner known per se, microperforations can be carried out either in the document itself, in particular when the latter is opaque, or only in the printing layers of the document when the latter is transparent, for example in the case of a transparent plastic film, or even in an insert, such as a patch or a strip, which is then fixed on the document. The microperforations according to the invention can even be non-opening or be covered by a film or a pellet as soon as the thickness of material closing the microperforation is of sufficient transparency to allow observation of the shape of the microperforation by transparency. .
En référence à la figure 1, celle-ci illustre un premier mode de réalisation dans lequel les signes 1 constituant la série de signes réalisés par les microperçages ont des formes différentes, de préférence des for- mes suffisamment complexes pour qu'ils soient difficiles à réaliser manuellement ou avec un outillage rudimen- taire, mais d'une forme suffisamment identifiable pour être reconnue d'un coup d'œil. En particulier ces signes pourraient avoir la forme de caractères alphabétiques ou numériques. Dans ce mode de réalisation, l'encodage est réalisé par la séquence des signes de formes différentes de sorte que toute modification de la séquence correspond à une information différente. A titre d'exemple on peut ainsi encoder le numéro de série 8 du billet. Lors d'un contrôle le numéro de série est relevé sur le billet et est soumis à un algorithme de cryptage identique à celui qui a servi à élaborer la série de signes 1. La comparaison du résultat avec la série de signes perforés sur le billet permet de vérifier si le billet est authentique.With reference to FIG. 1, this illustrates a first embodiment in which the signs 1 constituting the series of signs produced by the microperforations have different shapes, preferably shapes which are sufficiently complex to make them difficult to perform manually or with rudimentary tools, but in a form that is sufficiently identifiable to be recognized at a glance. In particular, these signs could take the form of alphabetic characters or digital. In this embodiment, the encoding is carried out by the sequence of the signs of different shapes so that any modification of the sequence corresponds to different information. As an example, we can encode the serial number 8 of the ticket. During a check, the serial number is noted on the ticket and is subject to an encryption algorithm identical to that which was used to develop the series of signs 1. The comparison of the result with the series of perforated signs on the ticket allows to check if the ticket is authentic.
La figure 2 illustre un mode de réalisation dans lequel les signes 2 sont tous en forme d'étoiles qui sont réalisées selon des tailles différentes, l'encodage d'une information de sécurisation étant réalisé par la séquence des tailles des étoiles.FIG. 2 illustrates an embodiment in which the signs 2 are all in the form of stars which are produced according to different sizes, the encoding of security information being carried out by the sequence of the sizes of the stars.
La figure 3 illustre un mode de réalisation dans lequel les signes sont tous des flèches 3 qui sont différentes les unes des autres par leur orientation.FIG. 3 illustrates an embodiment in which the signs are all arrows 3 which are different from each other by their orientation.
La figure 4 illustre des signes en forme de dou- blés triangles accolés 4 qui se différencient les uns des autres par leur position relative, le décodage de ces signes pouvant être effectué par référence à une matrice .FIG. 4 illustrates signs in the form of double contiguous triangles 4 which differ from one another by their relative position, the decoding of these signs being able to be carried out by reference to a matrix.
La figure 5 illustre des signes 5 en forme de gouttes qui se différencient les uns des autres d'une part par la distance dl, d2 qui sépare le signe d'un élément de repère porté par le billet de banque, ici le coin supérieur gauche 9 de la lettre E du terme EURO, d'autre part par l'angle Al, A2 qui sépare une ligne horizontale de la ligne joignant le signe à l'élément de référence. Sur la figure 6, les signes 6 se différencient par leur distance par dl, d2 , par rapport à une bande 7 imprimée sur le billet de banque ou fixée sur celui-ci, ou encore insérée dans celui-ci.FIG. 5 illustrates signs 5 in the form of drops which differ from one another on the one hand by the distance dl, d2 which separates the sign from a reference element carried by the bank note, here the upper left corner 9 of the letter E of the term EURO, on the other hand by the angle Al, A2 which separates a horizontal line from the line joining the sign to the reference element. In FIG. 6, the signs 6 are differentiated by their distance by dl, d2, with respect to a strip 7 printed on the bank note or fixed on it, or even inserted therein.
Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et on peut y apporter des variantes de réalisation sans sortir du cadre de l'invention tel que défini par les revendications.Of course, the invention is not limited to embodiment described and it is possible to add variants without departing from the scope of the invention as defined by the claims.
En particulier, au lieu d'apparaître directement comme illustré sur les figures, le codage peut être révélé par un phénomène de moirage par pliage du billet ou par superposition d'un filtre indépendant du billet. Le codage peut être répété plusieurs fois afin de fournir des informations redondantes facilitant la relecture. Il est également possible d'effectuer cette redondance avec des codages différents permettant un recoupement.In particular, instead of appearing directly as illustrated in the figures, the coding can be revealed by a moiré phenomenon by folding the ticket or by superposition of a filter independent of the ticket. The coding can be repeated several times to provide redundant information to facilitate re-reading. It is also possible to carry out this redundancy with different codings allowing an overlap.
Le codage selon l'invention peut être utilisé pour mettre en œuvre le procédé de sécurisation décrit dans le document FR-A-2.800.896, l'authentifiant prévu dans ce procédé étant mémorisé sur le billet par la série de microperçages réalisés selon l'invention.The coding according to the invention can be used to implement the security method described in document FR-A-2,800,896, the authenticator provided for in this method being stored on the ticket by the series of microperforations produced according to the invention.
Les microperçages peuvent être réalisés par tous moyens appropriés, en particulier par gravure au moyen d'un faisceau laser, éventuellement associé à un réseau de micro-miroirs, ce qui permet de générer numériquement un très grand nombre de formes variées en agissant sur les micro-miroirs constituant le réseau, de sorte que les signes obtenus sont difficilement reproductibles avec des moyens artisanaux. Les signes réalisés peuvent être des trous débouchants sur les deux faces du document ou des trous borgnes débouchant sur une seule face, voire même des cavités non débouchantes réalisées par une focalisation du laser à l'intérieur de la matière.Micro-drilling can be carried out by any appropriate means, in particular by etching by means of a laser beam, possibly associated with a network of micro-mirrors, which makes it possible to digitally generate a very large number of varied shapes by acting on the micro - mirrors constituting the network, so that the signs obtained are difficult to reproduce with artisanal means. The signs produced may be through holes on both sides of the document or blind holes opening out on one side, or even non-emerging cavities produced by focusing the laser inside the material.
Bien qu'en relation avec les figures 5 et 6 les signes aient été décrits comme se différenciant par leur position par rapport à un élément de repère rapporté sur le billet, on peut utiliser un élément de repère du document lui-même, par exemple un coin ou un bord du billet.Although in relation to FIGS. 5 and 6, the signs have been described as being differentiated by their position relative to a reference element attached to the ticket, it is possible to use a reference element from the document itself, for example a corner or edge of the ticket.
Bien que dans le mode de réalisation de la figure 1 la série de microperçages corresponde à un encodage du numéro de série imprimé sur le billet lui-même, l'information de sécurisation à laquelle correspond la série de microperçages n'est pas nécessairement portée par le billet. Cette information peut être mémorisée par ailleurs et comparée à l'information obtenue par décodage de la série de microperçages . Although in the embodiment of the figure 1 the series of micro-holes corresponds to an encoding of the serial number printed on the ticket itself, the security information to which the series of micro-holes corresponds is not necessarily carried by the ticket. This information can be stored elsewhere and compared with the information obtained by decoding the series of microperforations.
