Definitions

  • the invention relates to methods for verifying the authenticity of different securities containing identification elements, with preliminary control testing and can be used for determining the authenticity of documents which are assigned individual signs, for example, numbers, bar codes etc.
  • One of such methods is the method for verifying the authenticity of banknotes and other financial documents based on measurement of two independent individual space-extended features of the processed document, one of which is determined by the paper production technology and the other - by the polygraphic document printing method [I].
  • the document surface is irradiated with two scanning optical beams with different wavelengths.
  • the document is showed through with one beam, and the transmitted light flux is converted into the first electric signal and it is formed the first digital code constituting the feature of the texture of paper.
  • the other beam is reflected from the document surface and the reflected light flux is converted into the second digital code constituting the printing feature of the document.
  • control testing is carried out during document printing performing the same operations and in the same succession as during verification of its authenticity.
  • the reference value is saved in the created database of the identification system and is used further on for comparison with the value obtained in the verification process.
  • the comparison result establishes the authenticity of document at the value coincidence and counterfeit thereof- at noncoincidence.
  • the closest by the technical essence to the claimed invention is the method for controlling the authenticity of documents described in the international application N° WO 9523388 [2].
  • verification of the authenticity of document, having at least one individual identifying sign is carried out by means of reading, particularly scanning and/or photographing with the help of optical appliance by a device on base of photosensor, at least of one specified part of the document, containing figurative elements used for identification and an individual identifying sign, recordings, in pixels, of the light flux intensity reflected by the part with figurative elements and individual identifying sign, retention similarly of the recorded information of the original document in the database of the document identification system, use of an individual identifying sign as document address in the database of the identification system, automatic or manual comparison of at least one selected for verification specified part with figurative identifying elements of the verified document with the corresponding part of the original document contained in the database of the identification system, at the same time the part with figurative identifying elements is placed in the same place of the document with respect to the individual identifying sign.
  • Each recorded specified part of the document contains two pixels, the figurative pattern thereof is digitized, and each pixel is specified in the shape of bit chain corresponding to the reflected light intensity.
  • the achievement state-of-the-art in the high technology field permits to manufacture counterfeit documents with high degree of accuracy, particularly to perform a high-grade counterfeit of any figurative patterns applied on the document, as well as to take into account the intensity of the reflected therefrom light flux.
  • the main disadvantage of the described method consists in the insufficiently high degree of certainty of identifying the authenticity of the verified document, limited by the use as identification criterion of distribution of the light intensity reflected by raster points of the figurative pattern, situated on the selected for verification part of the document.
  • the given method resides disadvantages peculiar to the earlier described analogue.
  • the problem undertaken by the author of the invention consists in elaborating a sufficiently feasible and reliable verification method providing a high degree of certainty of identifying the authenticity of document.
  • the undertaken problem is solved at the expense of the fact that in the proposed method for verifying the authenticity of document, having at least one individual identifying sign, carried out by means of reading, particularly scanning and/or photographing with the help of optical appliance by a device on base of photosensor, at least of one specified part of the document, containing figurative elements used for identification and an individual identifying sign, recordings, in pixels, of the light flux intensity reflected by the part with figurative elements and of the individual identifying sign, retention similarly of the recorded information of the original document in the database of the document identification system, use of an individual identifying sign as document address in the database of the identification system, automatic or manual comparison of at least one selected for verification specified part with figurative identifying elements of the verified document with the corresponding part of the original document contained in the database of the identification system, in addition the part with figurative identifying elements is placed in the same place of the document with respect to the individual identifying sign, the part of the document selected for verification is scanned with a resolving capacity no less than 600 pixels per inch, and as

Abstract

L'invention porte sur des procédés pour vérifier l'authenticité de différents titres contenant des éléments d'identification, avec un test de contrôle préliminaire, et qui peuvent être utilisés pour déterminer l'authenticité de documents auxquels on a attribué des signes individuels, par exemple, des numéros, des codes à barres, etc. Ceci est réalisé au moyen d'une lecture, à savoir un balayage et/ou une photographie, à l'aide d'un appareil optique par un dispositif basé sur un photodétecteur, d'au moins une partie spécifiée du document, contenant des éléments figuratifs utilisés pour l'identification et un signe d'identification individuel, au moyen d'enregistrements, dans des pixels, de l'intensité de flux lumineux réfléchie par la partie avec des éléments figuratifs et un signe d'identification individuel, au moyen d'une rétention analogue des informations enregistrées du document initial dans la base de données du système d'identification de document, au moyen d'une utilisation d'un signe d'identification individuel en tant qu'adresse de document dans la base de données du système d'identification, au moyen d'une comparaison automatique ou manuelle d'au moins une partie pour vérification de partie spécifiée, avec des éléments d'identification figuratifs du document vérifié, avec la partie correspondante du document initial contenu dans la base de données du système d'identification. Selon l'invention, au niveau de la partie avec les éléments figuratifs qui est placée dans le même endroit que le document par rapport au signe d'identification individuel, la partie du document sélectionné pour une vérification est balayée avec une capacité de résolution non inférieure à 600 pixels par pouce, et en tant qu'éléments d'identification figuratifs est utilisé le relief de surface du document choisi pour une partie de vérification et/ou motif, formé sur le relief durant le contact de colorant avec la surface. Le résultat obtenu par la présente invention consiste à augmenter le degré de certitude de vérification de l'authenticité de différents documents au moyen d'un ou plusieurs procédés simples et fiables.
