Definitions
- the present invention relates generally to measurements can be taken to mark security documents such as banknotes, in an emergency context.
- the invention thus finds a particularly advantageous application in the emergency marking of security documents during a aggression, so as to invalidate the documents, and / or to then allow recognition of documents stolen during the attack.
- the object of the invention is thus a method of securing documents, including the steps of integrating into each documents a safety sign during its production, said safety sign can be altered by revealing means, said revealing means being intended to be used to alter in an emergency the characteristics of the safety sign.
- a second type of known process consists in triggering in the event means of burning documents.
- Such means may for example include means of triggering of an explosion.
- a first drawback of this second type of process is that it generates smoke that could annoy people in the vicinity proximity during the explosion and subsequent combustion.
- combustion does indeed invalidate a certain number of documents, it does not allow them to be marked so specific, which can however be searched to identify a document stolen in special circumstances.
- a third type of known process consists in smearing tickets automatically with ink in case of assault.
- the attackers can in any event develop "deinking" products whose role is to erase ink used to mark documents.
- This document discloses specific means for spraying by marking ink a set of security documents.
- the ink is used as a developer of a invisible sign which was integrated into the documents during their manufacture.
- thermosensitive printing sheet comprising microcapsules pressure sensitive, used as a safety feature.
- the object of the invention is to meet this need.
- the invention proposes, according to a first aspect a method for securing documents, comprising the steps consisting in integrating in each document a security sign during its manufacturing, said safety sign being able to be altered by means developers, said developer means being intended to be used to alter the characteristics of the safety sign in an emergency, characterized in that the method also includes association with security sign, during the production of the document, of an active element capable to convert some of the electromagnetic radiation from heat trigger to visibly alter the appearance of the document, and the implementation of the revealing means is triggered by electromagnetic triggering radiation.
- the invention also provides a device emergency marking of security documents, including means of implementing revealing means in a process such as mentioned above, characterized in that said means for setting artwork include microwave emission means.
- the invention finally proposes the application of a process as mentioned above for securing paper documents or plastic.
- the method according to the invention comprises the steps consisting in integrating in each document a security sign during its manufacturing, said safety sign being able to be altered by means developers, said developer means being intended to be used to alter the characteristics of the safety sign in an emergency.
- the active element which is integrated in each document, in association with the safety sign, receives the radiation of microwave trigger even if the document is at the heart of a bundle.
- microwave radiation does not meet difficulty entering the core of bundles, unlike an ink that would widespread.
- the device for implementing such a method may include a enclosure in which the bundles of documents are placed, a source microwave radiation being provided in the enclosure.
- the safety sign can be made so as to be imperceptible when it has not been activated by the active element, following exposure of the document with trigger radiation.
- the sign of security and the active element are combined and constitute only one entity.
- This entity (which we will simply designate in this first variant by the term "active element") can be any product capable of converting a part of the electromagnetic radiation triggering heat in view to visibly alter the appearance of the document.
- the alteration of the appearance of the document can thus consist of a evolution of the color of the safety sign produced in the form of a polymer, following heating: the polymer can indeed be chosen to change color, or become visible, under the effect of heat.
- a polymer invisible at room temperature can thus under the effect of microwave radiation generate heat, which causes itself the alteration of the optical properties of the polymer, so as to reveal a sign, such as a reason that the document has been Fly.
- the polymer can also be chosen to promote an effect of pathway (creation of a conductive carbon film), as a result of the rise in temperature caused by the heating of the polymer.
- composition of polymer can be adapted, for example by choosing a compound to melanin base.
- the active element and the security sign are distinct.
- the metal is not directly sensitive to radiation; it only plays the role of the safety sign.
- the metal can in this case be associated with the active element by embedding the metal in a varnish containing the active element, or by alloy, or by any other technique.
- the active element comprises capsules able to release a revealing product when exposed to electromagnetic triggering radiation.
- the capsules can thus comprise a polymer coating or in any product capable of both sealingly containing the product developer at room temperature, and to release this product from a certain heating temperature.
- the overheating results here again from exposure to the radiation of trigger: it can be caused by the revealing product which is inside the capsules, and / or by the coating of the capsules itself.
- the developer - which can be integrated, for example in ink - is the security sign.
- the revealing product can be a dye capable of sublimating under the effect exposure to heat, to go directly into the gas phase.
- composition of such an ink can be adapted by incorporating fatty additives (which are sensitive to sublimable dyes, and which allow to reveal them during their sublimation to change the appearance of the document), and / or by choosing the properties of the ink base (inks with UV drying or drying by the action of an electron beam).
- fatty additives which are sensitive to sublimable dyes, and which allow to reveal them during their sublimation to change the appearance of the document
- the specific properties of the active element may arise from the very nature of the active element, and thus exist at individual level of each active element particle.
- the properties of the active element and / or the product revealing are actually those of the particulate set formed by the active element particles and the host medium.
- the invention makes it possible to trigger particularly efficient marking of documents, even if they are at the heart of a bundle.
- the safety signs will be advantageously distributed in several places on the surface of the document. This guarantees that, in the event of a trip, different areas of the document are altered.
- Documents that can be protected in this way can be made from sheets of paper.

Abstract
Description
- Le rayonnement électromagnétique de déclenchement est un rayonnement micro-ondes,
- ledit élément actif est un élément métallique,
- ledit élément métallique présente un point de fusion suffisamment bas pour fondre suite au dégagement de chaleur issu de la conversion d'une partie du rayonnement électromagnétique de déclenchement,
- ledit élément actif est une colle thermosensible,
- ledit élément actif est un polymère,
- ledit élément actif comprend des capsules aptes à libérer un produit révélateur lorsqu'elles sont exposées au rayonnement électromagnétique de déclenchement,
- ladite association d'un élément actif au signe de sécurité est réalisée par
l'une ou plusieurs des méthodes suivantes :
- intégration au document d'une encre comportant l'élément actif,
-
intégration au document d'un fil de sécurité, -
intégration au document d'un film de transfert, -
intégration au document de fibres, - ladite association est réalisée par intégration au document d'une encre, et l'élément actif comporte des colorants pouvant être sublimés suite à l'exposition au dégagement de chaleur issu de la conversion d'une partie du rayonnement électromagnétique de déclenchement,
- les moyens révélateurs comprennent un élément métallique,
- les moyens révélateurs comprennent une colle thermosensible.
- le procédé comprend également lors de la fabrication du document l'association au signe de sécurité d'un élément actif apte à convertir une partie du rayonnement électromagnétique de déclenchement en chaleur en vue d'altérer de manière visible l'aspect du document,
- et la mise en oeuvre des moyens révélateurs est déclenchée par un rayonnement électromagnétique de déclenchement. Le rayonnement de déclenchement est de préférence un rayonnement micro-ondes.
- manuellement (par un convoyeur de fond ou autre),
- ou automatiquement :
- à distance (en fonction des signaux transmis par une caméra de surveillance ou tout autre capteur à un central de neutralisation des documents, qui dispose lui-même de moyens de commande à distance de l'activation de la source micro-ondes),
-
ou en local (en fonction ici encore de signaux de surveillance issus de capteurs optiques ou autres).
- à partir de poudre et/ou fibres et/ou micro fibres de carbone amorphe ou
actif (un tel carbone en poudre peut être obtenu par les procédés
industriels connus , dit au four, au gaz, ou à la cheminée, ou par d'autres
procédés destinés habituellement à produire des « charbons » tels que
la pyrolyse thermique ou chimique ).
-
Le carbone étant un bon conducteur calorifique, il favorise en outre l'échauffement de la partie du document à laquelle il est associé, et peut provoquer le noircissement, voire la combustion du document, - à partir de poudre ou fibres de graphite,
- à partir de métal, en particulier un métal qui réagit fortement à
l'exposition à un rayonnement micro-ondes en convertissant une partie
très importante du rayonnement en énergie calorifique.
-
Un tel élément métallique s'échauffe lorsqu'il est exposé au rayonnement de déclenchement.
Et cet échauffement résulte en une altération de cette entité unique qui est à la fois signe de sécurité et élément actif. Ici encore, l'altération peut consister en un noircissement du document, voire en sa combustion si l'échauffement est suffisamment important. On pourra adapter la puissance du rayonnement de déclenchement et les caractéristiques du métal du signe de sécurité à cet effet, -
Alternativement, il est également possible de choisir un métal qui à la fois soit sensible au rayonnement micro ondes (sensible directement, car les propriétés intrinsèques du métal font que celui-ci convertit une partie de l'énergie du rayonnement en chaleur), et ait un point de fusion suffisamment bas pour que la chaleur engendrée par le rayonnement micro ondes provoque la fusion du métal.
Dans ce cas, le métal sera de préférence incorporé au document sous la forme d'une poudre ou de paillettes intégrées au billet par impression ou autre, le métal se solidifiant de nouveau en refroidissant après sa fusion (en formant ainsi des amas solides tels que des plaques).
Ainsi, non seulement la fusion du métal engendrera un changement d'aspect du document (l'impression de poudre ou paillettes ayant été dégradée en un amas de métal fondu), mais en outre les caractéristiques mécaniques de ce document sont également altérées, ce qui le rend reconnaissable au toucher.
Et les plaques ou autres amas solides consécutifs à la fusion du métal peuvent de plus détériorer ensuite l'aspect des autres éléments imprimés du document, lors de chaque manipulation.
A titre d'exemple, on pourra ainsi incorporer à des encres (imprimables par exemple en sérigraphie)des pigments à l'état micronisé obtenus à partir de métaux tels que l'étain, ou à partir d'alliages (tels que le zamac), dont les points de fusion sont de l'ordre de 200°C à 300°C.
On remarquera que dans cette variante, le métal fondu d'un document peut en outre se répandre sur les documents voisins d'une liasse, de manière à les maculer également, - A partir d'une colle thermosensible, qui devient activement collante à
partir d'une certaine température.
-
Dans ce cas, la colle est ici encore directement sensible au rayonnement micro ondes pour en transformer une partie en chaleur. En s'échauffant, la colle se liquéfie et macule les documents voisins d'une liasse. Et en se refroidissant, la liasse de documents se trouve prise en masse par la colle ; ainsi non seulement on a modifié l'aspect du document mais on a en outre totalement empêché son utilisation, - à partir de poudre ou fibres de tout composé issu de la chimie minérale (
exemple : ferrite de Nickel, et/ou Cuivre et/ou Manganèse et/ou Zinc,
magnétite de synthèse ou d'origine naturelle, etc ...) ou organo minérale
ou organo métallique, présentant des propriétés de magnétisme doux
et/ou des propriétés de conductibilité électrique ou de semi conducteurs.
-
On précise que sont particulièrement bien adaptés les métaux qui favorisent l'apparition et le développement de courants de Foucault, sous exposition à un champ électromagnétique, - à partir de polymères : l'entité unique constituée par le signe de sécurité et l'élément actif peut également être un polymère dont les propriétés sont altérées en cas d'échauffement consécutif à l'exposition à un rayonnement micro-ondes. Cette altération se traduit en particulier par une altération d'aspect.
- d'une encre (par exemple sous la forme d'une poudre métallique ou d'un polymère),
- de fils de sécurité que l'on intègre dans la trame fibreuse du document, ou entre deux de ses feuilles si le document est réalisé en un laminé de plastique (fils comprenant une poudre métallique et/ou un polymère et/ou un dépôt - par exemple sous vide - de métal),
- d'un film de transfert-(« foils » selon la terminologie anglo-saxonne). Un tel film de transfert peut être intégré dans le document à chaud ou à froid ; il peut mettre en oeuvre par exemple une poudre métallique et/ou un polymère et/ou un dépôt de métal. A cet égard, des hologrammes peuvent être déposés sur les documents et jouer le rôle d'élément actif et de signe de sécurité, des caractéristiques de l'hologramme telles que l'épaisseur de la couche d'aluminium (ou de métal) de l'hologramme pouvant être adaptées pour que l'hologramme réagisse de manière visible au rayonnement de déclenchement,
- de fibres (métalliques et/ou polymères),
- etc...
