Anti-counterfeiting texture recognition method

Abstract

The invention discloses an anti-counterfeiting texture recognition method. The method includes the following steps that: a) an anti-counterfeiting information carrier with a random texture structure is selected as a printing area for a code identifier or graphic & text identifier on a printed material; b) the printed material is printed, so that the code identifier or graphic & text identifier can be formed, wherein the code identifier or graphic & text identifier at least partially covers the random texture structure on the anti-counterfeiting information carrier; and c) the overlapping point of the code identifier or graphic & text identifier and the random texture structure is obtained and is adopted as anti-counterfeiting feature record information. With the anti-counterfeiting texture recognition method of the present invention adopted, requirements for the clarity of the random texture structure can be lowered, the complexity of subsequent recognition processing can be greatly simplified, and recognition accuracy can be improved; and since the texture structure is randomly generated, the overlapping point covered by codes, graphs or texts is also random, and therefore, anti-counterfeiting difficulty can be greatly increased, and stolen anti-counterfeiting data can be prevented from being applied to counterfeiting. The anti-counterfeiting texture recognition method is simple in process and easy to implement and popularize.

Description

technical field [0001] The invention relates to an anti-counterfeiting method, in particular to an anti-counterfeiting texture identification method. Background technique [0002] Texture anti-counterfeiting is an anti-counterfeiting technology that uses the inherent markings on packaging materials as anti-counterfeiting identification marks. Patterns in nature are always varied, such as fingerprints, wood grains, stone patterns, zebra patterns, ice patterns, dry cracked ground and other textures are random and unique, and it is impossible for two to be exactly the same. Using this principle, the anti-counterfeit label is made of clear-textured packaging materials, and the markings of each label material are photographed, numbered, archived, and stored in the anti-counterfeit database. [0003] In addition, the diffusion lines of printed codes or printed graphics are randomly curved micro-curves, which are random, unique, and non-reproducible. Therefore, use the raised dif...

Problems solved by technology

[0004] However, whether it is a natural texture structure or a random zigzag pattern formed by printing, there are still the following disadvantages in actual anti-counterfeiting applications: 1. The texture characteristics may not be clear enough and lack of personalization; 2. The coding / graphic diffusion pattern itself is prone to deformation , fading, and ultimately greatly increase the difficulty of recognition; 3. The judgment and processing of texture similarity is more complicated, and it is difficult to ensure a high degree of recognition
