Anti-counterfeiting system, anti-counterfeiting method and anti-counterfeiting and identification unit for safety file

Abstract

The invention discloses an anti-counterfeiting system, an anti-counterfeiting method and an anti-counterfeiting and identification unit for a safety file and relates to the field of safety of the safety file. The anti-counterfeiting method comprises the following steps: testing at least one actual tolerance of at least one pattern unit in the safety file and establishing a facticity matching relation between the actual tolerance and identification information of the safety file; identifying the identification information of the safety file to be identified and a corresponding detection tolerance of the corresponding pattern unit, comparing the identification information of the safety file to be identified with the facticity matching relation of the safety file and according to a comparison result, determining facticity of the safety file to be identified. According to the invention, counterfeiting prevention of the safety file is implemented on the basis of the tolerance generated in the production process of the safety file; possibility that the safety file is counterfeited is greatly reduced; the anti-counterfeiting ability of the safety file is improved.

Description

technical field [0001] The invention relates to the security field of security documents, in particular to an anti-counterfeiting system, an anti-counterfeiting method and an anti-counterfeiting and authentication unit for security documents realized based on the tolerance generated in the production process of the security documents. Background technique [0002] The anti-counterfeiting technology of valuable documents is mainly divided into physical anti-counterfeiting technology and digital anti-counterfeiting technology. In the past, physical anti-counterfeiting technology was dominant. With the rapid development of information technology, digital anti-counterfeiting technology has become more and more widely used. Digital anti-counterfeiting technology usually adopts digital printing, two-dimensional code, etc., and uses certain security algorithms to realize the anti-counterfeiting of valuable documents. [0003] Both physical and digital anti-counterfeiting technolog...

Problems solved by technology

Specifically, with the exchange of scientific and technological information, physical anti-counterfeiting technology is becoming more and more easy to be imitated by criminals; while digital anti-counterfeiting technology can effectively protect the anti-counterfeiting technology from being cracked through encryption algorithms, but the combination with the protected valuable documents It is difficult to guarantee, and the production of many valuable items is not suitable for digital printing, QR code and other technologies
