Abstract
Description
La présente invention concerne un procédé de sécurisation d'articles sensibles, et un article sensible objet d'un tel procédé.The present invention relates to a method for securing articles sensitive, and a sensitive article subject to such a process.
L'invention trouve une application avantageuse dans la fabrication de billets de banque ou de documents fiduciaires, mais peut également s'appliquer à la fabrication d'étiquettes d'authentification de produits sensibles ou à la sécurisation de tout produit sensible.The invention finds an advantageous application in the manufacture of bank notes or fiduciary documents but can also apply to the manufacture of product authentication labels sensitive or to the security of any sensitive product.
On connaít de nombreuses techniques pour associer à un objet un marquage imperceptible à un observateur, mais pouvant être reconnu par une machine à des fins d'authentification.We know many techniques to associate an object with a marking imperceptible to an observer, but which can be recognized by a machine for authentication purposes.
Il est ainsi connu d'intégrer dans des billets de banque des marquages invisibles à l'oeil nu, mais possédant des propriétés optiques, électromagnétiques ou électriques spécifiques, seules des machines adaptées pouvant déterminer la présence de ces propriétés.It is thus known to integrate into banknotes markings invisible to the naked eye, but having optical properties, electromagnetic or electrical specific, only machines adapted to determine the presence of these properties.
Plus précisément, il existe des procédés permettant d'intégrer dans le papier de billets de banque des fibres, par exemple métalliques, ayant des propriétés électriques ou électromagnétiques spécifiques, reconnaissables à distance par des machines aptes à émettre un signal d'excitation des fibres et à recueillir et reconnaítre une signature spécifique desdites fibres.More specifically, there are methods for integrating into banknote paper of fibers, for example metallic, having specific electrical or electromagnetic properties, remotely recognizable by machines capable of transmitting a signal excitation of the fibers and to collect and recognize a specific signature of said fibers.
On trouvera un exemple d'un tel procédé dans le brevet US 4 265
703.
Les fibres peuvent ainsi être détectables par lecture hyperfréquence (de
type micro-ondes en particulier) ou par mesure de champ magnétique (les
fibres fournissant alors une signature magnétique spécifique).An example of such a method can be found in US Patent 4,265,703.
The fibers can thus be detectable by microwave reading (microwave type in particular) or by magnetic field measurement (the fibers then providing a specific magnetic signature).
De telles dispositions constituent des éléments de sécurité des billets, mais ne garantissent pas de manière absolue l'absence de contrefaçon car il est toujours possible que des faussaires aient connaissance des caractéristiques de la réponse attendue des billets à une excitation d'authentification, et élaborent des moyens de marquage reproduisant ces caractéristiques.Such provisions constitute security features for tickets, but do not absolutely guarantee the absence of counterfeiting because it is always possible that counterfeiters have knowledge of the characteristics of the expected response of tickets to a excitement of authentication, and develop means of marking reproducing these characteristics.
Par ailleurs, il serait avantageux, dans certaines circonstances, de distinguer plus particulièrement un lot donné de billets ou de produits sensibles par un marquage spécifique, afin de suivre le cheminement de ces billets ou objets une fois mis en circulation.In addition, it would be advantageous in certain circumstances to more specifically distinguish a given batch of tickets or products sensitive by a specific marking, in order to follow the path of these notes or objects once put into circulation.
Ceci pourrait être utilisé pour établir une traçabilité du cheminement du lot spécifique, à des fins statistiques par exemple. On pourrait ainsi imaginer d'associer à un lot particulier de produits tels que des flacons de parfum un tel marquage spécifique, pour visualiser la diffusion géographique des flacons de ce lot. Ceci pourrait également être mis en oeuvre pour le marquage de lots de billets de banque particuliers.This could be used to establish tracking of the route of the specific lot, for statistical purposes for example. We could thus imagine associating with a particular batch of products such as vials of perfume such a specific marking, to visualize the diffusion geographic of the bottles in this batch. This could also be implemented work for the marking of batches of particular banknotes.
Un but de l'invention est de permettre de réaliser un marquage d'objets sensibles tels que des billets de banque, avec un niveau de sécurité accru par rapport aux dispositions connues évoquées ci-dessus.An object of the invention is to allow marking sensitive objects such as banknotes, with a level of increased security compared to the known arrangements mentioned above.

D'autres aspects, buts et avantages de l'invention apparaítront mieux à la lecture de la description suivante de formes préférées de réalisation de l'invention, qui est faite en référence au marquage de billets de banque, mais on comprendra que l'invention peut être mise en oeuvre avec tout type d'article sensible.Other aspects, aims and advantages of the invention will appear better on reading the following description of preferred embodiments of the invention, which is made with reference to the marking of banknotes, but it will be understood that the invention can be implemented with any type sensitive article.
On a dit qu'il était connu d'associer à des billets de banque des moyens de marquage imperceptible à un observateur tels que des fibres métalliques, dont la présence dans le billet ne peut être reconnue que par une machine adaptée. De telles fibres constituent ainsi des marqueurs de sécurité du billet. Et il est possible d'associer à un billet d'autres types de marqueurs, ayant une propriété physique, chimique, voire biologique, particulière.It was said that it was known to associate banknotes with means of marking imperceptible to an observer such as fibers metallic, whose presence in the ticket can only be recognized by a suitable machine. Such fibers thus constitute markers of ticket security. And it is possible to associate other types of markers, having a physical, chemical or even biological property, special.
On va maintenant décrire un billet comportant un marqueur de sécurité dont, selon l'invention, la réponse caractéristique à une émission d'excitation peut être modifiée si désiré.We will now describe a ticket with a marker security including, according to the invention, the characteristic response to a transmission excitation can be changed if desired.
Ainsi, selon un aspect essentiel de l'invention, il est possible de traiter spécifiquement un billet ou un lot de billets particulier pour modifier la réponse des billets du lot à l'excitation de la machine d'authentification.Thus, according to an essential aspect of the invention, it is possible to specifically process a particular ticket or batch of tickets to change the response of the batch tickets to the excitation of the authentication machine.
Selon un premier mode de réalisation, la trame fibreuse des billets peut comprendre des fibres métalliques dont une machine d'authentification est apte à déterminer la conductivité électrique.According to a first embodiment, the fibrous frame of the banknotes may include metallic fibers including an authentication machine is able to determine the electrical conductivity.
Pour être intégrables dans le papier du billet et esthétiquement acceptables, ces fibres doivent avoir un diamètre adapté (60 µm maximum pour un papier dont le grammage est de l'ordre de 100 g/m2), avec d'une longueur pouvant aller jusqu'à quelques centimètres.To be integrable in the ticket paper and aesthetically acceptable, these fibers must have a suitable diameter (60 µm maximum for a paper whose grammage is around 100 g / m 2 ), with a length of up to 'a few centimeters.
Lorsqu'on expose un billet contenant de telles fibres à un rayonnement de micro ondes, une partie de ce rayonnement est absorbée par les fibres tandis que la partie non absorbée est réfléchie.When a ticket containing such fibers is exposed to a microwave radiation, part of this radiation is absorbed by the fibers while the unabsorbed part is reflected.
Et le rapport entre la partie réfléchie et la partie absorbée dépend des caractéristiques des fibres, entre autres de leur diamètre ou d'une dimension caractéristique, de leur longueur, et de l'implantation des fibres dans le billet (concentration et dispersion des fibres).And the ratio between the reflected part and the absorbed part depends characteristics of the fibers, including their diameter or a characteristic dimension, their length, and the location of the fibers in the ticket (concentration and dispersion of fibers).
Ainsi, il est possible de concevoir une machine d'authentification munie de moyens d'émission de rayonnement micro ondes, et de moyens de réception et de mesure de la partie du rayonnement réfléchie. Une telle machine permet de caractériser la présence des fibres dans les billets, et les caractéristiques des fibres énoncées ci-dessus.Thus, it is possible to design an authentication machine provided with means for emitting microwave radiation, and means of reception and measurement of the part of the reflected radiation. Such a machine to characterize the presence of fibers in banknotes, and the characteristics of the fibers set out above.
Le rapport entre l'énergie micro ondes réfléchie et absorbée peut ainsi être défini comme représentatif d'une conductivité micro ondes des fibres. Et cette conductivité est directement liée aux caractéristiques des fibres, et en particulier à leur longueur. The relationship between reflected and absorbed microwave energy can thus be defined as representative of a microwave conductivity of fibers. And this conductivity is directly linked to the characteristics of the fibers, and in particular their length.
Pour distinguer les billets du lot choisi, on modifie selon l'invention la conductivité des fibres présentes dans ces billets particuliers en mettant en oeuvre une technique de modification de conductivité actionnable à distance tel que décrite ci-dessous.To distinguish the tickets of the chosen lot, the invention is modified conductivity of the fibers present in these particular notes by putting in uses a technique for modifying conductivity that can be activated distance as described below.
Pour mettre en oeuvre une telle modification de la conductivité des fibres et selon un premier mode de réalisation, au moins certaines desdites fibres ont été constituées en deux ou plusieurs tronçons de fibre, les tronçons étant reliés deux à deux par des microactionneurs.To implement such a modification of the conductivity of fibers and according to a first embodiment, at least some of said fibers were made up of two or more sections of fiber, the sections being linked two by two by microactuators.
Un microactionneur est une nanostructure constituée par dépôt sous vide (ou éventuellement par une autre technique, par exemple dépôt électrolytique) de couches de particules sur un substrat (de silicium par exemple).A microactuator is a nanostructure formed by deposition under empty (or possibly by another technique, for example deposit electrolytic) of layers of particles on a substrate (of silicon by example).
Et il est possible de modifier l'état d'un tel microactionneur par exposition à un champ électrique. En fonction des caractéristiques du microactionneur, la valeur de seuil du champ électrique au-delà de laquelle la structure du microactionneur est modifiée peut être très faible.And it is possible to modify the state of such a microactuator by exposure to an electric field. Depending on the characteristics of the microactuator, the threshold value of the electric field beyond which the structure of the microactuator is modified can be very weak.
Toutefois, dans le cadre de l'invention, on mettra en oeuvre des microactionneur dont la structure ne peut être modifiée que par exposition à un champ supérieur à un seuil de l'ordre de quelques dizaines de Volt, de préférence de l'ordre de 150 Volt.However, in the context of the invention, use will be made of microactuator whose structure can only be modified by exposure to a field greater than a threshold of the order of a few tens of Volts, of preferably around 150 Volt.
Plus précisément, les microactionneurs sont déposés à l'aide de masques de manière à relier deux tronçons de fibres.More specifically, the microactuators are deposited using masks so as to connect two sections of fibers.
Les tronçons de fibre ont quant à eux été constitués par découpage par attaque chimique d'une fibre, qui a été elle-même fabriquée par dépôts de métal électriquement conducteur sur un substrat tel que du silicium.The fiber sections were formed by cutting by chemical attack on a fiber, which was itself produced by deposits of electrically conductive metal on a substrate such as silicon.
De tels dépôts peuvent avoir une épaisseur totale de l'ordre de quelques microns à quelques dizaines de microns. L'attaque chimique peut être réalisée par dépôt d'acide ou de soude, en fonction du métal constitutif de la fibre.Such deposits can have a total thickness of the order of a few microns to a few tens of microns. Chemical attack can be made by deposition of acid or soda, depending on the constituent metal fiber.
On constitue ainsi des billets comportant un marquage imperceptible sous la forme de fibres métalliques, les caractéristiques dudit marquage imperceptible pouvant être altérées suite à l'exposition du billet à un champ électrique supérieur au seuil mentionné plus haut.One thus constitutes tickets comprising an imperceptible marking in the form of metallic fibers, the characteristics of the said marking imperceptible that can be altered following the exposure of the ticket to a field electric above the threshold mentioned above.
En effet, si on expose ces billets à un champ électrique dont la valeur est supérieure à ce seuil, les microactionneurs sont activés de sorte que les tronçons de fibre sont disjoints les uns des autres, et la conductivité du billet s'en trouve modifiée.Indeed, if we expose these banknotes to an electric field whose value is greater than this threshold, the microactuators are activated so that the fiber sections are disjoint from each other, and the conductivity of the ticket is modified.
Ainsi, les microactionneurs jouent le rôle d'interrupteurs actionnables par exposition à un champ électrique, pour modifier la réponse du billet à l'exposition du rayonnement de la machine d'authentification.Thus, the microactuators play the role of actuable switches by exposure to an electric field, to modify the response of the ticket to the exposure of the authentication machine radiation.
Et étant donnée la valeur importante du seuil de champ électrique d'actionnement de microactionneurs, une modification intempestive de la structure des fibres, et donc des caractéristiques de la réponse du billet, est évitée.And given the important value of the electric field threshold actuation of microactuators, an untimely modification of the fiber structure, and therefore characteristics of the ticket response, is avoided.
Selon un mode de réalisation alternatif, les microactionneurs peuvent être remplacés par des structures se déformant géométriquement sous exposition à un champ magnétique, sous l'effet d'un phénomène de magnétostriction.According to an alternative embodiment, the microactuators can be replaced by geometrically deforming structures under exposure to a magnetic field, under the effect of a phenomenon of magnetostrictive.
Dans ce cas, la déformation de ces structures est adaptée pour séparer les tronçons de fibres, de sorte que la conductivité du billet est également altérée par suite de l'ouverture de l' « interrupteur » que constitue l'élément déformable.In this case, the deformation of these structures is suitable for separate the fiber sections, so that the conductivity of the ticket is also altered as a result of opening the "switch" that constitutes the deformable element.
Les marqueurs peuvent encore être fabriqués en utilisant une nappe de matériau ferroélectrique déposée sur un support polymère souple découpé en fibres, fils ou toute autre type de particule de faibles dimensions (jusqu'à quelques dizaines de micron en épaisseur et quelques mm2 en surface).The markers can also be manufactured using a sheet of ferroelectric material deposited on a flexible polymer support cut into fibers, wires or any other type of small particle (up to a few tens of microns in thickness and a few mm 2 on the surface) .
Ces particules peuvent ensuite être intégrées directement dans la trame du papier des billets, ou bien dans une encre d'impression du billet, ou encore déposés directement sur le billet (ils pourront dans ce cas être recouverts d'un vernis).These particles can then be incorporated directly into the weft of ticket paper, or in ticket printing ink, or deposited directly on the ticket (they can in this case be coated with varnish).
Ils peuvent être également fabriqués à partir d'un support en fil polymère de quelques microns de diamètre sur lequel on a déposé ces matériaux ferroélectriques suivis de leurs couches de protection. Le fil est ensuite lui-même déposé sur le papier, ou intégré à la trame du papier du billet. De cette manière, on combine les caractéristiques des matériaux ferroélectriques avec celles des fibres.They can also be made from a wire support polymer a few microns in diameter on which we deposited these ferroelectric materials followed by their protective layers. The wire is then itself deposited on the paper, or integrated into the frame of the paper of the ticket. In this way, we combine the characteristics of the materials ferroelectric with those of fibers.
On a dit qu'une application préférée de l'invention concernait la sécurisation des billets de banque; toutefois il est comme on l'a dit également possible de mettre l'invention en oeuvre sur d'autres types d'articles sensibles. En particulier, on pourra réaliser selon l'invention des articles ou documents de sécurité réalisés non pas sur un support papier, mais sur un support en polymère (billet à trame fibreuse comportant des polymères, ou supports de type carte de crédit, insertion dans une colle associée au support).It has been said that a preferred application of the invention relates to the securing banknotes; however it is as we said also possible to implement the invention on other types sensitive items. In particular, it will be possible according to the invention to produce security articles or documents produced not on paper, but on a polymer support (bank note with fibrous weft comprising polymers, or credit card-type supports, insertion into an adhesive associated with the support).
Il est donc possible selon l'invention de traiter spécifiquement un lot de produits sensibles tels que des billets, munis d'un marquage imperceptible, pour modifier les caractéristiques de ce marquage afin de distinguer le lot en question.It is therefore possible according to the invention to specifically treat a batch sensitive products such as tickets, marked imperceptible, to modify the characteristics of this marking in order to distinguish the lot in question.
Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits ci-dessus.Of course, the invention is not limited to the embodiments described above.
En particulier, il est possible de mettre en oeuvre l'invention de manière à contrôler les caractéristiques de la réponse des billets lorsque les fibres ont été disjointes.In particular, it is possible to implement the invention of so as to control the characteristics of the response of tickets when the fibers have been disjoined.
De la sorte, l'authentification par une machine peut résulter en :
- une valeur de billet valide, mais non modifié, si la réponse du billet est conforme à une réponse de référence de billet valide, mémorisée dans une mémoire de la machine d'authentification,
- une valeur de billet valide, modifié (billet valide que l'on a traité pour le marquer spécifiquement), ladite valeur de billet valide modifié étant également prédéfinie dans une mémoire de la machine d'authentification, et constituant une deuxième valeur de référence différente de la première,
- ou bien une valeur de billet non valide.
- a valid ticket value, but not modified, if the ticket response conforms to a valid ticket reference response, stored in a memory of the authentication machine,
- a valid, modified ticket value (valid ticket which has been processed to mark it specifically), said modified valid ticket value also being predefined in a memory of the authentication machine, and constituting a second reference value different from the first one,
- or an invalid ticket value.
Et le traitement de modification de réponse peut être irréversible, ou bien réversible.And response modification processing may be irreversible, or well reversible.
En outre, ce traitement peut être effectué à distance comme dans les modes de réalisation décrits ci-dessus (exposition à un champ électrique ou magnétique), mais également être effectué par contact avec les billets ou produits à modifier.In addition, this treatment can be carried out remotely as in embodiments described above (exposure to an electric field or magnetic), but also be done by contact with tickets or products to be modified.
Enfin, si une application préférée de l'invention consiste à modifier une réponse de type électrique (les fibres métalliques produisant un effet d'antenne pour absorber certaines micro ondes et en réfléchir d'autres), la réponse dont on souhaite altérer les caractéristiques peut également être magnétique (et l'altération de la réponse pourra dans ce cas consister en l'application d'un champ magnétique d'excitation de manière à provoquer une résonance magnétique et modifier les caractéristiques magnétiques des marqueurs, qui peuvent être des fibres à magnétisme doux).Finally, if a preferred application of the invention consists in modifying an electrical type response (the metallic fibers producing an effect antenna to absorb some microwaves and reflect others), the response whose characteristics one wishes to alter may also be magnetic (and the alteration of the response may in this case consist of the application of an excitation magnetic field so as to cause magnetic resonance and change the magnetic characteristics markers, which can be fibers with soft magnetism).
Et il est bien entendu possible de superposer en association avec un même objet sensible des marqueurs électriques et des marqueurs magnétiques, les machines d'authentification pouvant dans ce cas comporter des moyens pour exciter les marqueurs de l'objet et recevoir leur réponse uniquement électrique, ou uniquement magnétique, ou bien électrique et magnétique à la fois.And it is of course possible to overlap in combination with a same sensitive object of electrical markers and markers magnetic, authentication machines can in this case include means to excite the markers of the object and receive their response only electrical, or only magnetic, or electric and magnetic at the same time.
Et dans ce dernier cas, il est possible de ne modifier qu'un type de réponse (électrique ou magnétique) pour distinguer le produit que l'on souhaite suivre plus particulièrement.And in the latter case, it is possible to modify only one type of response (electric or magnetic) to distinguish the product wishes to follow more particularly.
