- the authentication device is cheap, reliable, easy to use and easy to transport,
- the authentication is discrete since no visible light is emitted by the authentication apparatus
- the treatment of the product can be carried out for a modest additional cost because only a small surface of the packaging or of the product itself can be secured for authentication, and that the treatment can be carried out by conventional means of 'impression,
- the authentication method is simple, within the reach of all controllers and usable in all countries.
- Authenticable remotely a visualization of the physical reaction of identification allowing to certify the origin of the product without contact and at a distance which can be between a few centimeters and more than one meter, knowing that the authentication of a document is produced either by direct contact between the authentication device and the document, or at a very short distance from the order of a few millimeters to a few centimeters at the most, the only authentication systems comparable to those described here are the RFID devices in which a chip is included in the product or its packaging and for which a remote reader emits radio frequency radiation allowing a feedback response of the device, such contactless systems allow a reading of the identification information to several meters.
- a product placed on a display unit is subject to ambient lighting, the product may be in the sun outdoors and be strongly lit, or indoors on a shelving height and dimly lit, and The product authentication can therefore be affected, for example it is totally impossible to authenticate labels with prints with optically variable inks or holograms under varying lighting conditions at a distance greater than forty centimeters.

Description
AUTHENTICABLE SECURITY ELEMENT AND DEVICE FOR AUTHENTICATING AUTHENTICABLE SECURITY ELEMENT AND DEVICE FOR AUTHENTICATING
THE SAME THE SAME
L'invention concerne un dispositif d'authentification discret réalisable à distance pour des produits à protéger vis-à-vis de la contrefaçon. The invention relates to a discrete authentication device remotely feasible for products to be protected against counterfeiting.
Les documents de sécurité tels que billets de banque, pièces d'identité, permis de conduire, cartes bancaires, tickets de voyages, vouchers, chèques, bon cadeaux, etc.. doivent être protégés contre la copie et disposer d'éléments permettant la vérification de manière certaine du document. Ces éléments sont des fils de sécurité, tels que par exemple ceux décrits dans les documents US 61 321 , EP 59 056, JP 63182497, des hologrammes, indiqués notamment dans US 3 552 853, US 3 668 795, JP 2009015338, US 2009154813, des encres optiquement variables, explicitées dans la demande WO 06117271 ou dans le brevet US 6 472 455, des films optiquement variables tel que décrits par exemple dans JP 2009107259, et différents marqueurs incorporés dans le corps du document ou à sa surface. Tous ces éléments de sécurité ont fait la preuve de leur efficacité au cours des années et sont largement utilisés, généralement en combinaison, dans les documents de sécurité, toutefois la détection de ces éléments, soit par un appareil automatique dans le cas des billets de banque, soit par un appareil transportable, se fait dans toutes les situations à une courte distance, de l'ordre de quelques centimètres tout au plus. Security documents such as banknotes, identity documents, driving licenses, bank cards, travel vouchers, vouchers, checks, gift certificates, etc. must be protected against copying and have elements allowing the verification in a certain way of the document. These elements are security threads, such as those described in documents US 61 321, EP 59 056, JP 63182497, holograms, indicated in particular in US 3,552,853, US 3,668,795, JP 2009015338, US 2009154813, optically variable inks, explained in the application WO 06117271 or in US Pat. No. 6,472,455, optically variable films as described, for example, in JP 2009107259, and various markers incorporated into the body of the document or on its surface. All these security features have proved their effectiveness over the years and are widely used, usually in combination, in security documents, however the detection of these elements, either by an automatic device in the case of banknotes or by a transportable device, is done in all situations at a short distance, of the order of a few centimeters at most.
Il se pose un problème spécifique pour la protection des marques et des produits et la détection de la contrefaçon en raison du fait que lorsque des produits contrefaits sont présents dans un commerce, notamment dans des états orientaux ou moyen orientaux, il est d'une part nécessaire de pouvoir les identifier de manière certaine et d'autre part il est indispensable que cette authentification s'effectue de manière discrète, sans que le commerçant s'en aperçoive, ces deux conditions devant être réunies pour qu'une police locale puisse intervenir et saisir la marchandise avant que le commerçant ait fermé sa boutique. Les éléments de sécurité classiquement connus ne sont pas efficaces dans la plupart des situations : There is a specific problem for the protection of trademarks and products and the detection of counterfeiting because of the fact that when counterfeit goods are present in a trade, particularly in Eastern or Middle Eastern states, it is on the one hand necessary to be able to identify them with certainty and secondly it is essential that this authentication is carried out in a discreet manner, without the merchant noticing, these two conditions must be met for a local police can intervene and seize the merchandise before the merchant has closed his shop. Conventionally known security features are not effective in most situations:
- les hologrammes sont maintenant couramment contrefaits et seuls les experts disposant d'un matériel sophistiqué sont capables de distinguer les originaux des contrefaçons, ce matériel n'est pas utilisable dans la situation de contrôle décrite précédemment,
les encres de sécurité à effets optiquement variables sont également aisément contretypées et ne peuvent pas être vérifiées à une distance de l'ordre de 1 m. - holograms are now commonly counterfeited and only experts with sophisticated hardware are able to distinguish originals from counterfeits, this material is not usable in the control situation described above, safety inks with optically variable effects are also easily reversed and can not be verified at a distance of about 1 m.
- les éléments de type fils de sécurité ou éléments inclus dans la masse de l'emballage ne peuvent généralement pas être employés en raison des coûts ou/et de la possibilité d'application, ils ne sont également pas vérifiables à distance. - The elements of the type of security son or elements included in the mass of the packaging can not generally be used because of the costs and / or the possibility of application, they are also not verifiable remotely.
Le problème à résoudre pour sécuriser et pour authentifier les marques et produits se pose de la manière suivante : - le produit doit disposer d'un dispositif évitant la reproduction à l'identique par les moyens accessibles à tout un chacun, c'est-à-dire par des moyens de reprographie couleur et par scannage puis impression avec des moyens domestiques, de type imprimante jet d'encre ou laser, - le produit doit disposer d'un moyen d'authentification à distance, l'élément de sécurité pouvant être porté par une étiquette, par le carton d'emballage ou par le produit lui-même, lequel produit pouvant être situé à une distance conséquente de l'appareil d'authentification actionné par le vérificateur, cette distance pouvant être de l'ordre de quelques dizaines de centimètres ou supérieure à un mètre, ce qui représente une distance de détection totalement hors de portée des techniques connues, The problem to be solved in order to secure and authenticate trademarks and products is as follows: - the product must have a device that avoids duplication by the means accessible to everyone, that is, by color reprographic means and by scanning and then printing with domestic means, such as an inkjet or laser printer, the product must have a means of remote authentication, the security element being able to be carried by a label, by the packaging carton or by the product itself, which product can be located at a substantial distance from the authentication device operated by the verifier, this distance can be of the order of a few tens of centimeters or greater than one meter, which represents a detection distance totally beyond the reach of known techniques,
- par ailleurs cette authentification doit pouvoir être réalisée dans des conditions variables de luminosité puisque le produit à vérifier peut se trouver à l'intérieur du commerce ou en plein soleil en extérieur, ce qui est également inhabituel et très défavorable par rapport aux conditions usuelles de vérification, - Moreover, this authentication must be able to be performed under varying lighting conditions since the product to be verified may be inside the trade or in full sun outside, which is also unusual and very unfavorable compared to the usual conditions of verification,
- bien évidemment le produit doit pouvoir être authentifié plusieurs fois sans laisser de trace et sans que l'élément de sécurité soit réalisable et visible par le possesseur du document, - obviously the product must be able to be authenticated several times without leaving a trace and without the security element being realizable and visible by the owner of the document,
- l'appareil d'authentification quant à lui doit être fiable, de faible coût et utilisable dans toutes les conditions climatiques pouvant être rencontrées par un contrôleur. - The authentication device meanwhile must be reliable, low cost and usable in all climatic conditions that may be encountered by a controller.
Le seul système connu pouvant répondre à la plupart des critères précédents est l'authentification radiofréquence, dite RFID, dans laquelle un système
électronique miniaturisé est inclus dans le produit ou son emballage, et porteur d'informations permettant l'authentification, le dispositif étant lu à distance au moyen d'un lecteur adapté émettant une onde dans le domaine des fréquences radio. Un tel dispositif est connu de longue date et appliqué dans le domaine des documents d'identité, des passeports notamment, et décrit dans différents brevets, par exemple, pour n'en citer que quelques uns, dans les documents WO 0036555, WO 05098748, WO 05100021 , WO 08119904, WO 2009007659, FR 2 899 000, EP 2 084 654, US 20030006121. Pour le problème spécifique à résoudre énoncé précédemment les dispositifs RFID possèdent plusieurs difficultés majeures qui les rendent peu favorables dans le présent contexte : The only known system that can meet most of the previous criteria is radio frequency authentication, known as RFID, in which a system Miniaturized electronic device is included in the product or its packaging, and carries information enabling authentication, the device being read remotely by means of a suitable reader emitting a wave in the radio frequency range. Such a device is known for a long time and applied in the field of identity documents, including passports, and described in various patents, for example, to name only a few, in WO 0036555, WO 05098748, WO 05100021, WO 08119904, WO 2009007659, FR 2 899 000, EP 2 084 654, US 20030006121. For the specific problem to be solved previously RFID devices have several major difficulties that make them unfavorable in the present context:
- le dispositif placé sur le produit, sous forme de puce par exemple, est coûteux et peu pratique à installer, très peu de transformateurs sont équipés pour réaliser cette opération simultanément à une impression, the device placed on the product, in the form of a chip for example, is expensive and impractical to install, very few transformers are equipped to perform this operation simultaneously with printing,
- le lecteur est coûteux et relativement encombrant, de plus des puces RFID contrefaites apparaissent sur le marché et cette protection technologique n'est plus une garantie vis-à-vis de la contrefaçon. - The reader is expensive and relatively bulky, more counterfeit RFID chips appear on the market and this technological protection is no longer a guarantee vis-à-vis the counterfeit.
L'invention a donc pour objectif de résoudre le problème spécifique énoncé précédemment en proposant un nouveau système d'authentification couplant un élément de sécurité rare avec un appareil d'authentification spécifique. The invention therefore aims to solve the specific problem stated above by proposing a new authentication system coupling a rare security element with a specific authentication device.
La présente invention concerne un dispositif authentifiable discret utilisable à distance pour un produit placé dans des conditions variables de luminosité au moyen d'un appareil d'authentification, ainsi que l'appareil d'authentification correspondant, le dispositif est caractérisé par le fait qu'il comporte au moins un élément de sécurité apposé sur ledit produit capable de développer une coloration sous l'action d'un rayonnement spatialement et temporellement cohérent, de type laser, émis par l'appareil d'authentification, et par le fait que ledit appareil d'authentification émet un rayonnement, sous la forme d'au moins un faisceau, permettant de couvrir une surface importante par un simple balayage unidirectionnel à une distance comprise entre quelques centimètres et plus d'un mètre, le rayonnement émis par l'appareil authentificateur étant situé hors du domaine de perception de l'œil.

- l'authentification est réalisable à une distance notable entre le produit et l'appareil d'authentification et dans des conditions variables de luminosité, The advantages of the system associating the security element and the specific authentication apparatus according to the invention are multiple: the authentication is feasible at a significant distance between the product and the authentication device and under varying lighting conditions,
- l'appareil d'authentification est bon marché, fiable, d'utilisation simple et facile à transporter, the authentication device is cheap, reliable, easy to use and easy to transport,
- l'authentification est discrète puisqu'aucune lumière visible n'est émise par l'appareil d'authentification, the authentication is discrete since no visible light is emitted by the authentication apparatus,
- l'authentification peut être réalisée très rapidement puisqu'un balayage du faisceau dans une seule direction permet de couvrir la surface à tester et de faire immédiatement apparaître une coloration spécifique, lorsque le produit est authentique, authentication can be carried out very quickly since scanning the beam in one direction only makes it possible to cover the surface to be tested and to immediately show a specific coloration, when the product is authentic,
- le traitement du produit peut être réalisé pour un surcoût modique en raison du fait que seule une petite surface de l'emballage ou du produit lui-même peut être sécurisée pour l'authentification, et que le traitement est réalisable par les moyens classiques d'impression, the treatment of the product can be carried out for a modest additional cost because only a small surface of the packaging or of the product itself can be secured for authentication, and that the treatment can be carried out by conventional means of 'impression,
- la méthode d'authentification est simple, à la portée de tous les contrôleurs et utilisable dans tous les pays. - the authentication method is simple, within the reach of all controllers and usable in all countries.
D'autres caractéristiques et avantages de l'invention se dégageront de la description qui va suivre. Dans la présente invention certains termes doivent être compris de la manière suivante : Other features and advantages of the invention will emerge from the description which follows. In the present invention certain terms should be understood as follows:
- Produit : toute matière commercialisable susceptible d'être contrefaite, cela va des matériaux de construction, des pièces détachées pour automobile ou l'aviation, en passant par les stylos, les produits de consommation courantes, les habits, jusqu'aux produits de luxe, les cosmétiques et les produits pharmaceutiques, tout étant actuellement contrefait ou susceptible d'être copié, les produits contrefaits étant estimés à environ 10% des produits commerciaux en circulation. - Product: any merchantable material that may be counterfeited, from building materials, automotive parts and aviation, to pens, consumer goods, clothes and luxury goods , cosmetics and pharmaceuticals, all of which are currently counterfeit or likely to be copied, with counterfeit products estimated at around 10% of the commercial products in circulation.
- Authentifiable à distance : une visualisation de la réaction physique d'identification permettant de certifier l'origine du produit sans contact et à une distance pouvant être comprise entre quelques centimètres et plus d'un mètre, sachant qu'usuellement l'authentification d'un document est réalisée soit par contact direct entre l'appareil d'authentification et le document, soit à une distance très courte de
l'ordre de quelques millimètres à quelques centimètres tout au plus, les seuls systèmes d'authentification comparables à ceux décrits ici sont les dispositifs RFID dans lesquels une puce est incluse dans le produit ou son emballage et pour lesquels un lecteur distant émet une radiation radiofréquence permettant une réponse en retour du dispositif, de tels systèmes sans contact permettent une lecture des informations d'identification à plusieurs mètres. - Authenticable remotely: a visualization of the physical reaction of identification allowing to certify the origin of the product without contact and at a distance which can be between a few centimeters and more than one meter, knowing that the authentication of a document is produced either by direct contact between the authentication device and the document, or at a very short distance from the order of a few millimeters to a few centimeters at the most, the only authentication systems comparable to those described here are the RFID devices in which a chip is included in the product or its packaging and for which a remote reader emits radio frequency radiation allowing a feedback response of the device, such contactless systems allow a reading of the identification information to several meters.
- Conditions variables de luminosité : un produit placé sur présentoir est soumis à l'éclairage ambiant, le produit peut se trouver au soleil en extérieur et être fortement éclairé, ou encore à l'intérieur sur un rayonnage en hauteur et faiblement éclairé, et l'authentification du produit peut donc en être affectée, il est par exemple totalement impossible d'authentifier des étiquettes comportant des impressions avec des encres optiquement variables ou des hologrammes dans des conditions variables d'éclairage à une distance supérieure à une quarantaine de centimètres. - Variable lighting conditions: a product placed on a display unit is subject to ambient lighting, the product may be in the sun outdoors and be strongly lit, or indoors on a shelving height and dimly lit, and The product authentication can therefore be affected, for example it is totally impossible to authenticate labels with prints with optically variable inks or holograms under varying lighting conditions at a distance greater than forty centimeters.
- Elément de sécurité : il doit être compris un ou plusieurs matériaux constitutifs, un ou plusieurs pigments minéraux ou organiques, colorants, polymères, de manière générale des éléments chimiques ou des combinaisons diverses susceptibles de produire la coloration sous l'action d'un rayonnement adapté. - Security element: it must be understood one or more constituent materials, one or more inorganic or organic pigments, dyes, polymers, generally chemical elements or various combinations capable of producing coloring under the action of radiation adapted.
Selon l'invention le produit est authentifiable à distance dans des conditions variables de luminosité au moyen d'un appareil d'authentification, l'invention concerne aussi l'appareil d'authentification correspondant, l'ensemble élément de sécurité - appareil d'authentification étant indissociable. According to the invention, the product can be authenticated remotely under variable lighting conditions by means of an authentication device, the invention also concerns the corresponding authentication device, the security element set - authentication device being inseparable.
L'invention concerne également une méthode d'authentification employant un élément de sécurité et un appareil d'authentification. The invention also relates to an authentication method employing a security element and an authentication apparatus.
Plus précisément la présente invention concerne l'authentification d'un produit par un appareil de test se situant à une distance comprise entre 20 centimètres et deux mètres. Le document de sécurité pouvant être placé selon une orientation quelconque par rapport à l'appareil d'authentification. More specifically, the present invention relates to the authentication of a product by a test apparatus being at a distance of between 20 centimeters and two meters. The security document can be placed in any orientation with respect to the authentication apparatus.
L'invention est caractérisée par le fait que le dispositif comporte au moins un élément de sécurité apposé sur le produit capable de développer une coloration sous l'action d'un rayonnement spatialement et temporellement cohérent, de type laser, émis par l'appareil d'authentification, et par le fait que ledit appareil d'authentification émet un rayonnement, sous la forme d'au moins un faisceau, permettant de couvrir une surface importante par un
simple balayage unidirectionnel à une distance comprise entre quelques centimètres et plus d'un mètre. The invention is characterized in that the device comprises at least one security element affixed to the product capable of developing a coloration under the action of a spatially and temporally coherent laser-like radiation emitted by the device. authentication, and in that said authentication apparatus emits radiation, in the form of at least one beam, for covering a large area by a simple unidirectional scanning at a distance of between a few centimeters and more than one meter.
Avantageusement le rayonnement émis par l'appareil authentificateur est situé hors du domaine de perception de l'œil afin que les vérifications par les contrôleurs dans les commerces ou les zones marchandes puissent se faire discrètement. Il peut cependant être envisagé, bien que cela soit évidemment moins favorable, d'employer un rayonnement visible, notamment situé dans la limite de l'ultraviolet ou de l'infrarouge. Advantageously, the radiation emitted by the authenticator device is located outside the field of perception of the eye so that the verifications by the controllers in the shops or the shopping areas can be done discreetly. However, it may be envisaged, although this is obviously less favorable, to use visible radiation, especially located in the ultraviolet or infrared limit.
Selon l'invention le faisceau de l'appareil authentificateur se présente sous forme d'une ligne présentant une longueur d'au moins 5 cm à une distance d'un mètre, et avantageusement de plus de 10 cm. According to the invention the beam of the authenticator device is in the form of a line having a length of at least 5 cm at a distance of one meter, and preferably more than 10 cm.
Selon une deuxième variante le faisceau peut aussi se présenter sous forme d'une croix dont chaque segment vertical ou horizontal présente une longueur d'au moins 5 cm à une distance d'un mètre, et avantageusement de plus de 10 cm. According to a second variant, the beam may also be in the form of a cross of which each vertical or horizontal segment has a length of at least 5 cm at a distance of one meter, and advantageously of more than 10 cm.
Le faisceau doit être suffisamment large pour aisément couvrir la zone portant l'élément de sécurité à une distance pouvant être supérieure à un mètre, par ailleurs ladite zone portant l'élément de sécurité doit être suffisamment grande pour que le passage du rayonnement produise l'émission d'une coloration aisément perceptible. The beam must be sufficiently wide to easily cover the area carrying the security element at a distance that may be greater than one meter, moreover said zone carrying the security element must be large enough for the passage of the radiation to produce the beam. emission of an easily perceptible coloration.
Le rayonnement peut être produit par plusieurs faisceaux, de structures identiques ou différentes, dans des domaines de longueurs d'ondes voisines ou différentes, par exemple un faisceau dans l'ultraviolet et un faisceau dans l'infrarouge, l'un se présentant sous forme d'une ligne et l'autre sous forme d'une croix, sans sortir du cadre de l'invention. The radiation can be produced by several beams, of identical or different structures, in neighboring or different wavelength domains, for example a beam in the ultraviolet and a beam in the infrared, one being in the form of one line and the other in the form of a cross, without departing from the scope of the invention.
La zone à contrôler peut être très variable, il peut s'agir d'un emplacement de quelques millimètres carrés placé en un endroit spécifique du produit ou de son emballage, il peut s'agir de quelques centimètres carrés sur une zone imprimée, laquelle pouvant être colorée ou non, il peut aussi s'agir d'un revêtement sur la totalité de la surface de l'étiquette ou de l'emballage d'un produit bien que cela soit à l'évidence plus coûteux. The area to be controlled may be very variable, it may be a location of a few square millimeters placed in a specific place of the product or its packaging, it may be a few square centimeters on a printed area, which may be be colored or not, it may also be a coating on the entire surface of the label or the packaging of a product although it is obviously more expensive.
La coloration développée par l'élément de sécurité sous l'action du rayonnement authentificateur est réversible, soit immédiatement après coupure du faisceau, soit après un temps bref si l'élément de sécurité est susceptible de développer de la phosphorescence. De manière avantageuse la coloration développée est intense, c'est-à-dire visible à une distance
pouvant atteindre plus d'un mètre en plein soleil, ou plusieurs mètres dans l'obscurité, sous l'action de l'appareil d'authentification selon l'invention. The coloration developed by the security element under the action of the authenticator radiation is reversible, either immediately after cutting the beam, or after a short time if the security element is likely to develop phosphorescence. Advantageously, the developed coloration is intense, that is to say visible at a distance can reach more than one meter in full sun, or several meters in the dark, under the action of the authentication apparatus according to the invention.
L'élément de sécurité requis pour l'authentification est introduit par tous moyens envisageables sur le produit lui-même, par exemple dans un procédé de fabrication des plastiques, ou à la surface de son emballage, par exemple par un moyen d'impression appliqué en surface, ou encore par un moyen de transformation par une technique de transfert ou de pulvérisation, ou encore par un adhésif positionné entre des films de laminage, ou par l'intermédiaire d'une étiquette imprimée. Selon une première variante de l'invention le rayonnement émis est un rayonnement laser émettant de préférence dans une plage comprise entre 254 nm et 380 nm, dans l'ultraviolet. The security element required for authentication is introduced by any means conceivable on the product itself, for example in a plastics manufacturing process, or on the surface of its packaging, for example by an applied printing means. at the surface, or by means of transformation by a transfer or spray technique, or by an adhesive positioned between rolling films, or by means of a printed label. According to a first variant of the invention the emitted radiation is a laser radiation emitting preferably in a range between 254 nm and 380 nm, in the ultraviolet.
Selon cette première variante l'élément de sécurité produisant la coloration est un colorant ou un pigment fluorescent ou phosphorescent, émettant dans la zone visible du spectre sous l'action du rayonnement, la coloration émise étant perceptible à au moins 50 cm lorsque le produit à authentifier est placé au soleil et à au moins 1 m lorsqu'il est placé dans la pénombre ou en intérieur. According to this first variant, the security element producing the coloration is a dye or a fluorescent or phosphorescent pigment, emitting in the visible zone of the spectrum under the action of the radiation, the emitted color being perceptible at least 50 cm when the product to be authenticate is placed in the sun and at least 1 m when placed in dim light or indoors.
Selon une deuxième variante de l'invention le rayonnement émis est un rayonnement laser émettant de préférence au-dessus de 850 nm, dans l'infrarouge. According to a second variant of the invention the emitted radiation is a laser radiation emitting preferably above 850 nm, in the infrared.
Selon cette deuxième variante l'élément de sécurité produisant la coloration est un colorant ou un pigment anti-Stokes, émettant dans la zone visible du spectre sous l'action du rayonnement, la coloration émise étant perceptible à au moins 50 cm lorsque le produit à authentifier est placé au soleil et à au moins 1 m lorsqu'il est placé dans la pénombre ou en intérieur. According to this second variant, the security element producing the coloration is an anti-Stokes dye or pigment, emitting in the visible zone of the spectrum under the action of the radiation, the emitted color being perceptible at least 50 cm when the authenticate is placed in the sun and at least 1 m when placed in dim light or indoors.
Selon une troisième variante l'appareil d'authentification émet un rayonnement formé par deux faisceaux laser spatialement proches et parallèles, un laser émettant de préférence dans une plage comprise entre 254 nm et 380 nm, dans l'ultraviolet, et un laser émettant de préférence au- dessus de 850 nm, dans l'infrarouge, l'élément de sécurité étant alors composé d'un mélange de réactifs produisant une coloration visible sous UV et de réactifs anti-Stokes, plus avantageusement encore les colorations produites par les deux faisceaux seront différentes. Une telle authentification est très sophistiquée et très difficile à contretyper pour les faussaires. Lors du contrôle du produit il peut être envisagé d'actionner les deux faisceaux simultanément et le produit montrera deux colorations différentes proches
dans la zone de contrôle, ou d'actionner les faisceaux l'un après l'autre pour développer les colorations différentes successivement. According to a third variant, the authentication apparatus emits radiation formed by two spatially close and parallel laser beams, a laser emitting preferably in a range of between 254 nm and 380 nm, in the ultraviolet, and a laser emitting preferably above 850 nm, in the infrared, the security element then being composed of a mixture of reagents producing visible coloration under UV and anti-Stokes reagents, more advantageously still the colorations produced by the two beams will be different. Such authentication is very sophisticated and very difficult to counter for counterfeiters. During the control of the product it can be considered to operate the two beams simultaneously and the product will show two different colors close in the control zone, or to activate the beams one after another to develop the different colors successively.
Quelle que soit la variante l'élément de sécurité est avantageusement peu ou pas coloré en lumière du jour ou d'une couleur non gênante lorsque celui-ci est inclus dans une encre d'impression, un vernis ou un revêtement de surface. Whatever the variant, the security element is advantageously little or not colored in daylight or in a non-annoying color when it is included in a printing ink, a varnish or a surface coating.
L'invention concerne également une méthode d'authentification d'un produit à distance dans des conditions variables de luminosité au moyen d'un appareil d'authentification, caractérisée en ce que : - le produit porte au moins un élément de sécurité développant une coloration sous l'action d'un rayonnement spatialement et temporel lement cohérent, de type laser, émis par l'appareil d'authentification, lequel rayonnement étant soit un faisceau laser émettant une lumière infrarouge, plus particulièrement une lumière à 980 nm et l'élément de sécurité développant la coloration étant un pigment anti-Stokes, soit un faisceau laser émettant une lumière voisine de 360 nm et l'élément de sécurité développant la coloration étant un colorant ou un pigment fluorescent ou phosphorescent, soit deux faisceaux laser émettant un à 980 nm et l'autre à 360 nm et l'élément de sécurité combine un pigment anti-Stokes et un colorant ou un pigment fluorescent ou phosphorescent, l'appareil d'authentification émet un rayonnement permettant de couvrir une surface importante par un simple balayage unidirectionnel à une distance comprise entre quelques centimètres et plus d'un mètre, lequel rayonnement étant situé hors du domaine de perception de l'œil. la méthode d'authentification consistant pour la personne chargée de la vérification à balayer la zone du produit à vérifier au moyen du rayonnement émis par l'appareil d'authentification de manière à développer une coloration spécifique à la surface du produit, laquelle coloration disparaissant, soit immédiatement soit après un délai assez bref, lorsque le rayonnement est coupé ou que la faisceau est retiré. The invention also relates to a method for authenticating a product remotely under varying lighting conditions by means of an authentication device, characterized in that: the product carries at least one security element developing a coloring under the action of spatially and temporally coherent radiation, of laser type, emitted by the authentication apparatus, which radiation is either a laser beam emitting infrared light, more particularly a light at 980 nm and the element staining-resistant security device being an anti-Stokes pigment, ie a laser beam emitting a light close to 360 nm and the security element developing the staining being a dye or a fluorescent or phosphorescent pigment, or two laser beams emitting a 980 nm and the other at 360 nm and the security element combines an anti-Stokes pigment and a fluorescent dye or pigment or phosphor escent, the authentication apparatus emits radiation to cover a large area by a simple unidirectional scanning at a distance of between a few centimeters and more than one meter, which radiation is located outside the field of perception of the eye. the authentication method consisting for the person responsible for the verification to scan the area of the product to be verified by means of the radiation emitted by the authentication device so as to develop a specific coloration on the surface of the product, which color disappears, either immediately or after a short time, when the radiation is cut off or the beam is removed.
Les divers éléments de sécurité envisageables peuvent être choisis de différentes manières selon qu'une authentification unique est recherchée, par exemple au moyen d'un élément de sécurité très particulier non diffusé commercialement et fabriqué spécifiquement pour cette application, ou selon qu'une authentification avec des produits plus classiques est souhaitée. Dans la première situation la sécurisation du document est très élevée mais le coût de la protection est grand, dans la deuxième situation la protection est bon
marché et la protection plus faible. Les pigments et colorants anti-Stokes étant considérés comme coûteux et les pigments ou colorants fluorescents ou phosphorescents étant usuellement moins onéreux mais d'accès plus facile pour les faussaires. Les éléments de sécurité susceptibles de développer les colorations prévues dans la présente invention sont connus dans le domaine de la sécurité pour des applications d'authentification à courte distance pour le contrôle des billets de banque ou des passeports, de tels produits sont par exemple commercialisés par les sociétés Honeywell, Epolin, Capricon chemicals, Phosphor Technology, etc.... Dans la présente invention l'élément de sécurité est choisi en fonction de sa capacité à développer une coloration intense et aisément perceptible au soleil à une distance pouvant être de 30 cm à plus d'un mètre ainsi que pour sa stabilité par rapport au vieillissement lumière, de tels réactifs sont avantageusement des pigments minéraux intégrant des terres rares dans leur composition. The various possible security elements can be chosen in different ways depending on whether a single authentication is sought, for example by means of a very particular security element that is not commercially diffused and manufactured specifically for this application, or that authentication with more classic products is desired. In the first situation the security of the document is very high but the cost of the protection is great, in the second situation the protection is good market and weaker protection. The anti-Stokes pigments and dyes are considered expensive and the fluorescent or phosphorescent pigments or dyes are usually less expensive but easier to access for counterfeiters. The security elements capable of developing the colorations provided for in the present invention are known in the field of security for short-range authentication applications for the control of banknotes or passports, such products are for example marketed by Honeywell, Epolin, Capricon Chemicals, Phosphor Technology, etc. In the present invention the security element is selected according to its ability to develop an intense coloring and easily perceptible to the sun at a distance that can be 30 cm to more than one meter and for its stability with respect to light aging, such reagents are advantageously mineral pigments incorporating rare earths in their composition.
Outre les combinaisons « élément de sécurité - appareil d'authentification » décrites précédemment il est inclus dans la présente invention d'employer un couple unique dans lequel l'élément de sécurité réagit en absorbant la lumière non pas dans une plage de longueurs d'ondes mais à une longueur d'onde très spécifique émise par l'appareil d'authentification et éventuellement très étroite, et émet une lumière dans une zone de fréquence inhabituelle ou en une couleur très spécifique. In addition to the "security element-authentication device" combinations previously described, it is included in the present invention to employ a single pair in which the security element reacts by absorbing the light not in a wavelength range. but at a very specific wavelength emitted by the authentication device and possibly very narrow, and emits light in an unusual frequency zone or in a very specific color.

The security element can be included in an ink, a transparent varnish, an adhesive or directly in the form of a powder between films and be deposited in a uniform and homogeneous manner, it is also envisaged in the context of the invention that the security element is in the form of points of dimensions between 30 μ and 800 μ on the surface or in the texture of the product packaging, which points are included in an ink, a varnish, a plastic film, a adhesive or in the mass of the substrate itself, especially when said substrate is a paper or a cardboard.
L'appareil d'authentification selon l'invention comporte un dispositif permettant l'émission d'un rayonnement laser dans le domaine non perceptible à l'œil, c'est-à-dire en infrarouge ou/et en ultraviolet, toutefois il peut être ajouté en plus une lampe et un dispositif de focalisation permettant l'émission d'un faisceau lumineux blanc ou coloré favorisant le pointage du rayonnement de manière plus précise, bien que cela ne soit pas très discret pour la vérification, rien n'interdit par ailleurs d'inclure dans l'appareil d'authentification des dispositifs authentificateurs autres tels que lecteur
RFID, lecteur magnétique, lampe UV traditionnelle dans laquelle l'émission de lumière n'est pas un faisceau laser, et tout autre dispositif authentificateur connu ou de suivi du produit, notamment tous les systèmes de traçage connus tels que les codes à barres de diverses natures et moyens permettant de trouver des informations sur le produit tels que lieu de fabrication, imprimeurs, revendeurs, circuits de distribution, date de fabrication... The authentication apparatus according to the invention comprises a device allowing the emission of laser radiation in the field not perceptible to the eye, that is to say in the infrared and / or ultraviolet, however it can to be added in addition a lamp and a focusing device allowing the emission of a white or colored light beam favoring the pointing of the radiation in a more precise way, although that is not very discrete for the verification, nothing forbids by elsewhere to include in the authentication apparatus other authentication devices such as reader RFID, magnetic reader, traditional UV lamp in which the light emission is not a laser beam, and any other known authenticator device or product tracking, including all known tracing systems such as barcodes of various natures and means to find product information such as place of manufacture, printers, resellers, distribution channels, date of manufacture ...
Il est bien évidemment possible de coupler l'appareil d'authentification, ou de l'intégrer, avec un dispositif de type appareil photo, téléphone mobile, ordinateur portable, etc.. permettant la transmission des informations du produit, ses références et ses caractéristiques, par exemple, de manière à enregistrer et traiter automatiquement un problème de contrefaçon ou l'envoi des informations à distance pour vérification et suivi. It is of course possible to couple the authentication device, or to integrate it, with a device such as camera, mobile phone, laptop, etc., allowing the transmission of product information, its references and its characteristics. for example, to automatically record and process a counterfeit issue or send information remotely for verification and tracking.
L'appareil d'authentification se présenté avantageusement sous forme d'un tube cylindrique fin d'une longueur de l'ordre d'une dizaine de centimètres muni d'un bouton pression actionnant le rayonnement, toutefois sans sortir du cadre de l'invention différentes formes, configurations et dimensions sont envisageables pour ledit appareil d'authentification et il peut être envisagé de placer des lampes additionnelles, une lumière blanche notamment, pour améliorer les fonctionnalités de l'instrument de contrôle.
