Description
La présente invention concerne le domaine de la sécurisation des données de validation imprimées sur un ticket de jeu, et notamment un ticket de loterie à gain instantané. L'invention concerne également un procédé de sécurisation des données de validation ainsi qu'un lecteur optique d'un ticket de jeu.The present invention relates to the field of securing validation data printed on a game ticket, and in particular an instant win lottery ticket. The invention also relates to a method of securing the validation data and an optical reader of a game ticket.
Les données de validation d'un ticket de jeu, par exemple sous la forme d'un code à barres, constituent le code de validation identifiant de façon unique chaque ticket. Ces données nécessitent d'être accessibles à tout moment par exemple pour des questions de commercialisation et de paiement des lots. De telles données également nécessitent d'être sécurisées afin d'éviter les fraudes, notamment la duplication totale ou partielle du ticket de jeu qui permettrait au fraudeur de se faire payer plusieurs fois le gain associé au ticket.The validation data of a game ticket, for example in the form of a barcode, constitute the validation code uniquely identifying each ticket. These data need to be accessible at any time for example for marketing and payment of lots. Such data also need to be secured in order to avoid fraud, including the total or partial duplication of the game ticket that would allow the fraudster to be paid several times the gain associated with the ticket.
De nombreuses techniques de sécurisation des données de validation ont été mises au point, comme par exemple la dissimulation des données dans des motifs non significatifs mais très proches de celui utilisé pour les données comme par exemple les mouchetés impressionnistes, ou l'impression des données avec des encres de couleur présentant un faible contraste avec celles utilisées pour la zone de fond sur laquelle elles sont imprimées.Numerous techniques for securing validation data have been developed, such as the concealment of data in patterns that are insignificant but very similar to those used for data such as impressionistic speckles, or the printing of data with color inks having a low contrast with those used for the background area on which they are printed.
Chacune de ces techniques présente le désavantage que les données de validation sont directement accessibles à quiconque. Ainsi, un fraudeur muni d'un équipement courant du commerce, comme par exemple un scanneur de bonne qualité, est apte à acquérir la zone d'impression des données et de là à déterminer lesdites données de validation.Each of these techniques has the disadvantage that the validation data is directly accessible to anyone. Thus, a fraudster equipped with common commercial equipment, such as a good quality scanner, is able to acquire the print area of the data and from there to determine the validation data.
Le but de la présente invention est de résoudre le problème susmentionné en proposant un moyen efficace de sécurisation des données de validation interdisant un accès direct aux données de validation.The object of the present invention is to solve the aforementioned problem by providing an effective means of securing validation data prohibiting direct access to validation data.
A cet effet, l'invention a pour objet un ticket de jeu comportant des données de validation imprimées sur une face de celui-ci et recouvertes d'au moins une couche d'encre opaque à la lumière visible, caractérisé en ce que la au moins une couche d'encre est au moins partiellement transparente à une lumière de longueur d'onde différente de celle de la lumière visible.For this purpose, the subject of the invention is a game ticket comprising validation data printed on one side thereof and covered with at least one layer of ink opaque to visible light, characterized in that the at least one ink layer is at least partially transparent to light of a wavelength different from that of visible light.
Ainsi, les données de validation ne peuvent être lues ni par un être humain, ni par des équipements standards de reproduction ou de numérisation qui ne sont sensibles qu'à la lumière visible puisque les données sont recouvertes d'une couche opaque à cette lumière.Thus, the validation data can not be read by a human being, or by standard equipment for reproduction or digitization that is sensitive only to visible light since the data is covered with a layer opaque to this light.
Selon d'autres caractéristiques, le ticket de jeu comprend une ou plusieurs des caractéristiques suivantes:
- la au moins une couche d'encre est au moins partiellement transparente à une lumière de longueur d'onde infrarouge ;
- les données de validation sont intégrées dans une pellicule grattable ;
- les données de validation sont imprimées sur une couche d'encre grattable de la face du ticket, et les au moins une couche d'encre opaque à la lumière visible est grattable.
- the at least one ink layer is at least partially transparent to infrared wavelength light;
- the validation data is embedded in a scratch film;
- the validation data is printed on a scratch-resistant layer of the face of the ticket, and the at least one layer of opaque-light ink is scratchaable.
L'invention a également pour objet un lecteur optique de ticket de jeu comportant des moyens de capture de données de validation imprimées sur une face d'un ticket de jeu, caractérisé en ce qu'il comprend des moyens d'illumination de ladite face avec une lumière de longueur d'onde différente de celle de la lumière visible de manière à faire apparaître des données de validation imprimées sur ladite face et recouvertes d'un masque d'encre au moins partiellement transparent à ladite lumière, et en ce que les moyens de capture sont propres à acquérir les données de validation sous une telle lumière.The invention also relates to an optical game ticket reader comprising means for capturing validation data printed on a face of a game ticket, characterized in that it comprises means for illuminating said face with a light of a wavelength different from that of the visible light so as to show validation data printed on said face and covered with an ink mask at least partially transparent to said light, and in that the means are suitable for acquiring validation data under such light.
Selon une autre caractéristique du lecteur optique, les moyens d'illumination émettent une lumière de longueur d'onde infrarouge.According to another characteristic of the optical reader, the illumination means emit light of infrared wavelength.
L'invention a également pour objet un procédé de sécurisation de données de validation d'un ticket de jeu, comprenant une étape d'impression desdites données de validation sur une face du ticket de jeu, caractérisé en ce qu'il comprend une étape d'impression, sur les données de validation, d'au moins une couche d'encre opaque à la lumière visible et au moins partiellement transparente à une lumière de longueur d'onde différente de celle de la lumière visible.The invention also relates to a method for securing validation data of a game ticket, comprising a step of printing said validation data on a face of the game ticket, characterized in that it comprises a step of printing, on the validation data, at least one ink layer opaque to visible light and at least partially transparent to light of wavelength different from that of visible light.
Selon une autre caractéristique, le procédé de lecture de données de validation d'un ticket de jeu tel que défini ci-dessus est caractérisé en ce que l'étape d'impression desdites données de validation comprend :
- une étape d'impression d'une première couche grattable sur la face du ticket de jeux ; et
- une étape d'impression des données de validation sur ladite première couche grattable,
- a step of printing a first scratchable layer on the face of the game ticket; and
- a step of printing the validation data on said first scratchable layer,
L'invention a également pour objet un procédé de lecture de données de validation d'un ticket de jeu obtenu selon le procédé susmentionné, caractérisé en ce qu'il comporte, simultanément à une étape de capture des données de validation, une étape d'illumination de la face du ticket avec une lumière de longueur d'onde à laquelle la au moins une couche d'encre est au moins partiellement transparente.The subject of the invention is also a method for reading validation data of a game ticket obtained according to the aforementioned method, characterized in that it comprises, simultaneously with a step of capturing validation data, a step of illuminating the face of the ticket with wavelength light to which the at least one layer of ink is at least partially transparent.
L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple, et faite en relation avec les dessins annexés dans lesquels :
- la figure 1 est une vue de dessus d'un ticket de jeu selon le premier mode de réalisation de l'invention, illuminé par de la lumière visible ;
- la figure 2 est le même ticket mais illuminé par de la lumière infrarouge ; et
- la figure 3 illustre des étapes de fabrication d'une zone de données sécurisées selon un second mode de réalisation de l'invention.
- Figure 1 is a top view of a game ticket according to the first embodiment of the invention, illuminated by visible light;
- Figure 2 is the same ticket but illuminated by infrared light; and
- FIG. 3 illustrates steps of manufacturing a secure data area according to a second embodiment of the invention.
Sur la figure 1, un ticket de jeu 10 à gain instantané selon un premier mode de réalisation comporte, sur une face en carton 12 de celui-ci, une zone de jeu 14 ainsi qu'une zone de données sécurisée 16.In FIG. 1, an instant
La figure 1 illustre la situation dans laquelle le ticket est illuminé par une lumière visible, par exemple celle du jour, classiquement définie comme une lumière de longueur d'onde comprise entre environ 400 nanomètres et 800 nanomètres. La zone de données sécurisée 16 se présente alors sous la forme d'un masque monochrome ou polychrome opaque à la lumière visible qui ne laisse rien transparaître de données imprimées sous lui.FIG. 1 illustrates the situation in which the ticket is illuminated by visible light, for example that of the day, conventionally defined as light of wavelength between about 400 nanometers and 800 nanometers. The
On notera que le terme « opaque » renvoie ici au fait qu'un oeil humain ou un dispositif de lecture, par exemple un dispositif à balayage de type scanneur sensible à la lumière visible, ne peut discerner ce qui est présent sous ce masque.It should be noted that the term "opaque" refers here to the fact that a human eye or a reading device, for example a scanning device of scanner type sensitive to visible light, can discern what is present under this mask.
Bien entendu le masque pourrait être légèrement transparent à la lumière visible, tout en étant opaque au sens de l'invention.Of course the mask could be slightly transparent to visible light, while being opaque in the sense of the invention.
La zone 16 de données sécurisées comporte des données de validation, par exemple du type à code à barres, imprimées sur la face 12 de préférence en encre noire au moyen d'une technique d'impression par jet d'encre. La zone 16 comprend également une ou plusieurs couches d'encre, grattables ou non, imprimée(s) sur les données de validation pour former le masque opaque à la lumière visible.The
L'encre du masque est choisie pour être opaque à la lumière visible mais également pour être transparente ou semi-transparente à une lumière hors du domaine visible, et de préférence transparente ou semi-transparente à une lumière de longueur d'onde infrarouge supérieure à 800 nanomètres.The ink of the mask is chosen to be opaque to visible light but also to be transparent or semi-transparent to a light outside the visible range, and preferably transparent or semi-transparent to a light of infrared wavelength greater than 800 nanometers.
Par exemple pour le domaine des infra-rouges, des encres de couleurs primaires bleue, cyan, rouge-magenta ou jaune, ou toute combinaison de celles-ci peuvent être utilisées.For example, for the infra-red field, inks of blue, cyan, red-magenta or yellow primary colors, or any combination thereof, may be used.
Le domaine de l'infrarouge est particulièrement approprié à la sécurisation des données.The infrared domain is particularly suitable for securing data.
En effet, l'oeil humain n'étant pas sensible aux infrarouges, un être humain ne peut lire par lui-même des données cachées sous la couche d'encre et cela même si le ticket de jeux est illuminé par une lumière infrarouge. En effet, même dans ces conditions d'illumination, la couche d'encre apparaît toujours opaque à l'homme.Indeed, the human eye is not sensitive to infrared, a human being can not read by itself hidden data under the ink layer and this even if the game ticket is illuminated by infrared light. Indeed, even in these conditions of illumination, the ink layer always appears opaque to the man.
Ainsi, seul un lecteur optique selon l'invention, décrit ci-après est capable de lire les données de validation.Thus, only an optical reader according to the invention, described below is able to read the validation data.
En variante d'autres domaines de longueur d'onde peuvent être choisis comme par exemple le domaine des ultraviolets (UV).Alternatively other wavelength ranges may be chosen such as the ultraviolet (UV) domain.
Toutefois un tel domaine présente le désavantage de rendre visible à l'oeil humain des données de validation lorsque le ticket est illuminé par une source ultraviolette.However, such a field has the disadvantage of making visible to the human eye validation data when the ticket is illuminated by an ultraviolet source.
La figure 2 illustre le ticket de la figure 1 lorsqu'il est illuminé par une lumière infrarouge. Dans cette configuration, le masque de la zone 16 de données sécurisées s'estompe et laisse transparaître les données de validation, ici sous la forme d'un code à barres.Figure 2 illustrates the ticket of Figure 1 when illuminated by infrared light. In this configuration, the mask of the
Conformément à l'invention, il est également prévu un lecteur optique destiné à lire et traiter les données de validation d'un ticket selon l'invention.According to the invention, an optical reader is also provided for reading and processing the validation data of a ticket according to the invention.
Un tel lecteur optique comporte une source émettant une lumière dans les longueurs d'onde auxquelles le masque de la zone 16 est transparent ou semi-transparent, par exemple une source de lumière infrarouge dans le cas d'une transparence aux infrarouges ; et des moyens de capture des données de validation aptes à capturer celles-ci sous la lumière en cause. Ainsi, en activant simultanément la source et les moyens de capture, les données de validation sont ainsi acquises.Such an optical reader comprises a source emitting light in the wavelengths at which the mask of the
La sécurisation des données de validation selon l'invention a ainsi pour avantage:
- de permettre l'utilisation d'une encre traditionnelle pour les données de validation, compatible avec les groupes d'impression jet d'encre utilisés par les imprimeurs de ticket et évite donc tout surcoût significatif d'impression desdites données ;
- de dissimuler totalement la présence des données de validation imprimées sur le ticket, ce qui présente en outre un avantage esthétique;
- d'éviter l'utilisation de données de validation nécessitant la mise en oeuvre d'algorithmes coûteux ;
- de garantir la protection totale contre toute tentative de duplication totale ou partielle du ticket en utilisant des photocopieurs ou des scanners fonctionnant en lumière blanche.
- to allow the use of a traditional ink for the validation data, compatible with the inkjet printing units used by the ticket printers and thus avoids any significant extra cost of printing said data;
- completely conceal the presence of the validation data printed on the ticket, which also has an aesthetic advantage;
- to avoid the use of validation data requiring the implementation of expensive algorithms;
- to guarantee total protection against any attempt to duplicate the ticket in whole or in part by using photocopiers or scanners operating in white light.
Par ailleurs, l'utilisation du domaine infrarouge a pour avantage supplémentaire que seul un équipement dédié est capable de lire les données de validation dissimulées sous la couche d'encre puisque l'oeil humain est insensible aux infrarouges.Furthermore, the use of the infrared domain has the additional advantage that only a dedicated equipment is able to read the validation data hidden under the ink layer since the human eye is insensitive to infrared.
Dans le mode de réalisation décrit ci-dessus, il existe encore un risque de fraude connu sous le nom de "fraude par micro grattage" lorsque la couche d'encre selon l'invention est réalisée sous la forme d'une pellicule grattable.In the embodiment described above, there is still a risk of fraud known as "micro scratch fraud" when the The ink layer according to the invention is made in the form of a scratch-off film.
En effet, lorsque les données de validation sont protégées par une couche grattable, certains fraudeurs n'hésitent pas à ôter d'infimes parties de la couche en de multiples zones pour faire apparaître partiellement les données de validation et ainsi reconstituer ces dernières.Indeed, when the validation data is protected by a scratchable layer, some fraudsters do not hesitate to remove tiny parts of the layer in multiple areas to partially show the validation data and thus reconstruct them.
Ce type de fraudes nécessite alors un examen minutieux de la zone de données sécurisées pour pouvoir être révélées.This type of fraud then requires a close examination of the secure data area in order to be revealed.
De même, certains fraudeurs n'hésitent pas à gratter la couche, par micro grattage ou non, à lire les données de validation, puis à appliquer une nouvelle couche pour reconstruire à l'identique la zone de données sécurisées.Similarly, some fraudsters do not hesitate to scratch the layer, by micro scratching or not, to read the validation data, then to apply a new layer to rebuild identically the area of secure data.
Là encore une analyse fastidieuse est nécessaire pour mettre à jour de tels agissements.Here again a tedious analysis is necessary to update such actions.
Conformément à un second mode de réalisation de l'invention, ce type de problème est résolu en intégrant les données de validation directement à l'intérieur d'une pellicule grattable.According to a second embodiment of the invention, this type of problem is solved by integrating the validation data directly into a scratch-off film.
A la figure 3, qui illustre les étapes de fabrication d'une zone 20 de données sécurisées selon le second mode de réalisation, au moins une couche d'encre grattable 22 est imprimée sur la face 12 du ticket de jeu 10.In FIG. 3, which illustrates the steps of manufacturing a
Des données de validation 24, ici sous la forme d'un code à barres, sont ensuite imprimées sur la surface de la couche grattable 22.
Enfin, une ou plusieurs couches d'encre 26 grattable du type décrit précédemment, et de préférence du type au moins partiellement transparentes aux infrarouges, sont imprimées sur les données de validation afin de masquer celles-ci.Finally, one or more layers of scratch-off ink of the type described above, and preferably of the at least partially infrared-transparent type, are printed on the validation data in order to mask them.
On conçoit donc aisément qu'un fraudeur qui tenterait de gratter la zone 20 de données sécurisées endommagerait du même coût les données de validation, interdisant de ce fait leur lecture.It is therefore easy to understand that a fraudster who tries to scratch the
L'intégration des données de validation dans une pellicule grattable empêche donc toute fraude par (micro-) grattage.The integration of validation data in a scratch film thus prevents any fraud by (micro) scratching.
Il est par ailleurs à noter que cette technique d'intégration de données sensibles dans une pellicule grattable peut également être utilisée dans la zone de jeu du ticket. En effet, dans certains types de jeu à gratter, une ou plusieurs zones grattables mais non la totalité, doivent être grattées pour faire apparaître des motifs de jeux.It should also be noted that this technique of integrating sensitive data into a scratch-off film can also be used in the ticket game area. Indeed, in some types of scratch game, one or more scratchable areas but not all, must be scraped to reveal playing patterns.
Pour savoir si les zones non grattées restantes n'ont pas été micro-grattées, des données de validation sont intégrées à la pellicule grattable de la même manière que celle décrite précédemment.To find out if the remaining non-scratched areas have not been micro-scraped, validation data is integrated into the scrapable film in the same manner as described above.
Ainsi, la lecture par illumination avec la lumière appropriée des zones non grattées restantes à l'aide du lecteur précédemment décrit, permet de savoir si les données de validation contenues dans les pellicules non grattées sont intactes, et donc de déterminer avec certitude si une fraude par (micro-) grattage a été réalisée.Thus, the reading by illumination with the appropriate light remaining scratched areas using the previously described reader, to know if the validation data contained in the unscratched films are intact, and thus to determine with certainty if a fraud by (micro) scratching was carried out.
De préférence, les données de validation sont constituées de motifs ayant une forte densité spaciale tout en présentant une faible redondance.Preferably, the validation data consist of patterns having a high spatial density while having a low redundancy.
Bien entendu d'autres modes de réalisation sont possibles.Of course other embodiments are possible.
