Generation method, verification method and system of anti-counterfeit label and anti-counterfeit label

Abstract

The invention provides an anti-counterfeit label generation method, an anti-counterfeit label verification method, an anti-counterfeit label verification system and an anti-counterfeit label. The anti-counterfeit label generation method comprises the following steps: acquiring a surface character string contained in a two-dimensional code, combining the surface character string with an anti-counterfeit digital character string, calculating an MD5 value of the combined character string, and taking at least one bit of the MD5 value as an identifier; dividing the anti-counterfeiting digital character string into at least two character blocks, respectively endowing different character blocks with colors by utilizing a random algorithm, and arranging the character blocks and identifiers on a bottom layer label; dividing the two-dimensional code into at least two regions, respectively endowing different regions with colors by using a random algorithm, setting the two-dimensional code as a surface layer label, and reserving hole sites at positions, corresponding to identifiers in a bottom layer label, of the surface layer label; and outputting the surface layer label and the bottom layerlabel by using printing equipment, and attaching the surface, with the anti-counterfeiting digital characters, of the bottom layer label to the surface, opposite to the two-dimensional code, of the surface layer label to form the anti-counterfeiting label. According to the anti-counterfeit label, various encryption measures are combined with colors, so that the safety is greatly enhanced.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeit barcodes, in particular to an anti-counterfeit label generation method, verification method and system, and an anti-counterfeit label. Background technique [0002] Anti-counterfeiting labels are also called anti-counterfeiting marks and anti-counterfeiting trademarks, which can be pasted, printed, and transferred on the surface of the target object, or on the packaging of the target object, or on the accessories of the target object (such as commodity listings, business cards and anti-counterfeiting cards), and have anti-counterfeiting effects. logo. However, the current anti-counterfeiting labels are easy to copy or reuse, and cannot fully achieve the anti-counterfeiting identification effect of commodity authenticity verification. [0003] The main method of digital anti-counterfeiting is to use an encryption function to encrypt the orderly original numbers to achieve disorder, and th...
