Random color two-dimensional code based anti-counterfeiting method and device

Abstract

The invention discloses a random color two-dimensional code based anti-counterfeiting method, which comprises the steps of S1, adopting random color two-dimensional codes to be associated with anti-counterfeiting information, coding anti-counterfeiting information, association information and two-dimensional code color information through a database table, storing the coded information into a database, wherein the color of each two-dimensional code is allocated randomly; S2, processing the two-dimensional codes in the step S1 into tags which are attached to commodities or directly printing the two-dimensional codes on packages of commodities; S3, recognizing the anti-counterfeiting information, the association information and the two-dimensional code color information carried in the two-dimensional codes through a two-dimensional code recognition device; S4, performing color decoding on the two-dimensional code color information recognized in the step S3 through codes of the database table, and finally outputting the decoded colors according to a preset shape; and S5, distinguishing the authenticity according to the recognized anti-counterfeiting information. By adopting random color two-dimensional codes generated according to the method and a random background, a generated PDF with two-dimensional codes being vectors can be printed with high quality directly.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting technology of two-dimensional codes, in particular to an anti-counterfeiting method and device based on random color two-dimensional codes. Background technique [0002] Anti-counterfeiting technology refers to the measures taken to achieve the purpose of anti-counterfeiting. It can accurately identify the authenticity within a certain range and is not easy to be imitated and copied. Simply put, it is a technology to prevent counterfeiting and counterfeiting. Anti-counterfeiting is a measure taken to prevent imitation or reproduction for the purpose of deception without the permission of the owner. Anti-counterfeiting technology products are products with anti-counterfeiting functions made of anti-counterfeiting technology for the purpose of anti-counterfeiting. [0003] There are many types of anti-counterfeiting technologies, mainly including printing anti-counterfeiting technology, chemical...

Problems solved by technology

[0004] At present, there are such anti-counterfeiting methods on the market: by making special anti-counterfeiting textures or anti-counterfeiting QR codes, then taking pictures, analyzing and uploading them, and performing online comparisons. In the two processes of making texture anti-counterfeiting and die-cutting, data analysis errors are prone to occur, and a lot of manpower and material resources are invested
