Abstract

The method of numbering bank notes is based on generation of random numbers by an electronic random number generator, and recording the number in an electronic memory for subsequent validation of the bank note. The random number is formed of a least nine characters, which may be drawn from the usual ten digits, the alphabet or a set of symbols. The random number is then printed on one bank note, then a new random number generated for the next bank note. To validate the note an opto-electronic reader scans the number and a telecommunications link sends the number for comparison with the stored numbers of valid bank notes. A validation signal is then returned over the same telecommunications link.

Description

L'invention concerne un procédé de numérotation de sécurité de papiers-valeur, ainsi qu'un papier-valeur numéroté par la mise en oeuvre du procédé.The invention relates to a security numbering method for security papers, as well as a security paper numbered by the implementation of the method.

Un des éléments permettant, d'une part, de rendre difficile la contrefaçon des papiers-valeur et plus précisément des billes de banque et, d'autre part, de contrôler leur authenticité est l'impression d'une numérotation souvent alpha-numérique sur les billets.One of the elements making it possible, on the one hand, to make counterfeiting of security papers and more specifically banknotes difficult and, on the other hand, to control their authenticity is the printing of an often alpha-numeric numbering on the tickets.

Pour pouvoir faire face aux contrefacteurs, que l'évolution rapine des moyens techniques leur permet d'exécuter des contretaçons de nonne qualité, on a proposé différents procédés de numérotation faisant notamment intervenir différentes relations mathématques auxquelles les numéros des billets doivent satisfaire.In order to be able to face counterfeiters, whom the rapid development of technical means allows them to execute counterprocesses of good quality, various numbering methods have been proposed, making use in particular of different mathematical relationships which the ticket numbers must satisfy.

Néanmoins, les contrefacteurs arrive souvent à contourner ces difficultés et il faut avouer qu'un contrôle d'un numéro de papiers-vaieur qui doit répondre à une loi mathématique n'est pas aisé.However, counterfeiters often manage to circumvent these difficulties and it must be admitted that checking a number of credentials which must meet a mathematical law is not easy.

La présente invention a pour but de proposer un procédé de numérotation diminuant les risques de contrefaçon
Le procédé selon l'invention est caractérisé par le fait que pour chaque papier à numéroteur, on génère au moyen d'un dispositif électronique comprenant un générateur aléatoire, une série d'au moins 9 signes, chaque signe pouvant être choisi parmi les 10 chiffres, les lettres de l'alphabet et un groupe de symboles déterminés, ladite série étant diiiêrente pour chaque papier-valeur, que l'on imprime ladite série sur le papier-valeur et que l'on enregistre ladite série imprimés dans a mémoire d'un dispositif électronique pour permettre un contrôle d'authenticité ultérieur.The object of the present invention is to propose a numbering method reducing the risks of counterfeiting.
The method according to the invention is characterized in that for each numbering paper, a series of at least 9 signs is generated by means of an electronic device comprising a random generator, each sign being able to be chosen from among 10 figures , the letters of the alphabet and a group of determined symbols, said series being different for each value paper, printing said series on value paper and saving said series printed in a memory of an electronic device to allow a subsequent authenticity check.

En effet, en utilisant un générateur aléatoire, les chances pour qu'un contrefacteur puisse trouver une série existant sont infiniment petites, la série ne se trouvant pas à l'intérieur d'une numérotation continue.Indeed, by using a random generator, the chances that an infringer can find an existing series are infinitely small, the series not being inside a continuous numbering.

Selon une variante d'exécution préférée, la série de 9 signes vient en plus ne la numérotation habituelle, ainsi à partir du moment nu une série de 9 signes n'est utilisée qu'une seule fois pour un seul billet, les chancels pour que la combinaison du numéro de la série avec la série aléatoire de 9 signes soit trouvée par un contrefacteur est de 1 sur 1 milliard si la série contient uniquement 9 chiffres et beaucoup plus si l'on utilise aussi des caractères alphabétiques et des symboles. Si l'on génère des séries comprenant plus de 9 signes, la probabilité pour qu'un contrefacteur trouve la bonne combinaison est encore inférieure à 10-7.According to a preferred variant, the series of 9 signs comes in addition to the usual numbering, so from the naked moment a series of 9 signs is used only once for a single ticket, the chancels so that the combination of the serial number with the random series of 9 signs is found by a counterfeiter is 1 in 1 billion if the series contains only 9 digits and much more if we also use alphabetic characters and symbols. If you generate series with more than 9 signs, the probability that a counterfeiter will find the right combination is still less than 10-7.

Selon une autre variante d'exécution, on peut renoncer à une numérotation usuelle et liser seulement une numérotation aléatoire, mais pour ce cas, il laut que l'on choisisse une série ayant 9 signes an plus du nombre des billets que l'on désire imprimer. De cette manière, la probabilité pour que les signes cnoisis par un contrefacteur tombent sur une des séries utilisées lors de la numérotation est également de 1 sur 1 milliard.According to another variant of execution, one can give up a usual numbering and read only a random numbering, but for this case, it is necessary that one chooses a series having 9 signs an more of the number of the tickets which one wishes to print. In this way, the probability that the signs chosen by a counterfeiter will fall on one of the series used when numbering is also 1 in 1 billion.

Lorsqu'il s'agit d'impressions uniques, le dernier procédé est suffisant pour limiter les risques qu'une série soit reorise dans une proportion de i sur 1 milliard. Néanmoins, s i s'agit d' mpressions répétitives, il faut soit augmenter le nombre de signes utilisés, soit combiner ces signes avec un numéro de série qui sera différent pour chaque impression.When it comes to single prints, the latter is sufficient to limit the risk that a series will be reorized in a proportion of i in 1 billion. However, if these are repetitive prints, you must either increase the number of signs used, or combine these signs with a serial number which will be different for each print.

Ces signes générés et imprimés sur les billets par des moyens connus, tels que dispositifs à impression laser, sont enregistrés dans la mémoire d'un dispositif électronique, par exemple dans une banque centrale et un contrôle de l'authenticité pourra ainsi être fait en interrogeant ledit dispositif par des terminaux adéquats, que se soient des terminaux du type clavier d'ordinateur ou des terminaux du type lecture ou contrôle des cartes de crédit ou de chèques.These signs generated and printed on the banknotes by known means, such as laser printing devices, are recorded in the memory of an electronic device, for example in a central bank and a check of the authenticity can thus be done by interrogating said device by suitable terminals, whether terminals of the computer keyboard type or terminals of the type for reading or checking credit cards or checks.

L'invention concerne également les papiers-valeur, notamment des billets de banque imprimés, selon le procédé.The invention also relates to securities, in particular printed banknotes, according to the method.

A titre d'exemple, les billets de banque en Suisse sont numérotés de la manière suivante deux chiffres indiquant l'année d'impression suivis d'une lettre et 6 séries, par exemple 88 K 3267082 si maintenant on associe une série de 9 signes à cette numérotation, par exemple 326 007 896, la combinaison de ces deux chiffres imprimés l'une à côté de l'autre ou sur deux lignes sera unique et la probabilité de tomber sur cette combinaison est de 1 sur 1 milliard. On diminuera la probabilité de tomber sur cette combinaison si la série peut aussi comprendre des lettres et symboles, par exemple 3A6D27YZ9.For example, banknotes in Switzerland are numbered in the following way two figures indicating the year of printing followed by a letter and 6 series, for example 88 K 3267082 if now we associate a series of 9 signs at this numbering, for example 326 007 896, the combination of these two numbers printed one next to the other or on two lines will be unique and the probability of finding this combination is 1 in 1 billion. We will decrease the probability of finding this combination if the series can also include letters and symbols, for example 3A6D27YZ9.

L'invention concerne enfin l'utilisation d'un lecteur optoélectronique pour le contrôle de l'authenticité du billet. Ledit lecteur disponible au guichet d'une banque, voire d'un commerce, est relié par une ligne téléphonique au dispositif électronique dont la mémoire contient les séries utilisées et qui indique si la numérotation est authentique ou non. Finally, the invention relates to the use of an optoelectronic reader for checking the authenticity of the ticket. Said reader available at the counter of a bank, or even a trade, is connected by a telephone line to the electronic device whose memory contains the series used and which indicates whether the numbering is authentic or not.
