Commodity anti-counterfeiting code construction and verification method

Abstract

The invention belongs to the technical field of commodity digital counterfeit prevention, and particularly relates to a commodity anti-counterfeiting code construction and verification method. Since clear code MM with an algorithm pointer and concealed code YM with commodity circulation state Zk and commodity circulation path Lm are used as anti-counterfeiting codes, code security is improved, dynamic coding and verification can be realized, commodity circulation can be traced. According to the encoding technical scheme with the algorithm pointer, multiple communication ways, multi-role multi-direction true and false identification can be realized, commodity can be identified, complete anti-counterfeiting effectiveness can be ensured, anti-counterfeiting effect is improved comprehensively while anti-counterfeiting cost can be reduced, and channel conflict can be eliminated. By the new anti-counterfeiting and verification technical scheme, existing resources are utilized efficiency, and commodity anti-counterfeiting effects with low cost, operational easiness, reusability and multiple ways for inspection are achieved.

Description

technical field [0001] The invention belongs to the technical field of commodity digital anti-counterfeiting, and in particular relates to a method for constructing and verifying a commodity anti-counterfeiting code. Background technique [0002] The importance of anti-counterfeiting is self-evident, so I won't elaborate here. [0003] From the perspective of anti-counterfeiting code structure, common anti-counterfeiting methods can be divided into: [0004] 1. Clear code: use special materials, special patterns, special codes, etc. to make anti-counterfeiting marks, and identify authenticity through observation and comparison; generally speaking, the cost is high, and identification is difficult, especially the risk of reuse and embezzlement is high big. [0005] 2. Hidden code: hide all or part of the anti-counterfeiting code or logo and place the same part as the hidden part on a third party, and verify the authenticity by opening the hidden part and comparing it with t...

[0004] 1.

[0005] 2. Hidden code: hide all or part of the anti-counterfeiting code or logo and place the same part as the hidden part on a third party, and verify the authenticity by opening the hidden part and comparing it with the one placed by the third party; generally speaking, mostly Valid once, single-way verification, practicality and credibility are compromised

This method is simple and easy to operate, and the cost is extremely low, but the anti-counterfeiting effect is not good, because the main code and the secondary code have been marked on the product in a clear and static form before the product leaves the factory (possibly on the inner and outer packaging). This is easy for counterfeiters to copy or reuse, and because this method marks the main and secondary codes on the inner and outer two-layer packaging respectively, it is not convenient for multiple inquiries, that is, if you want to verify, you must destroy the outer packaging, which is extremely difficult. Greatly restrict the effective circulation of goods
