Commodity anti-counterfeiting code construction and verification method

Abstract

The invention relates to commodity anti-counterfeiting code construction and verification method. A plain code MM having an algorithm pointer and a hidden code YM having the commodity circulation state Zk and the commodity circulation path Lm are simultaneously used as an anti-counterfeiting code so that the confidentiality of the code can be increased and dynamic coding and verification can be realized and traceability of commodity circulation can be performed. The coding scheme with the algorithm pointer can also realize multiple communication paths, multi-character and multi-faceted authentication so that the authenticity of the anti-counterfeiting commodities can be distinguished, the authenticity of operators and channels can be distinguished through the design of the commodity circulation state Zk and the commodity circulation path Lm, the effectiveness of all-round anti-counterfeiting can be ensured, especially the anti-counterfeiting efficiency can be improved in an all-round way, the anti-counterfeiting cost can be reduced and the goods crossing phenomenon can be eliminated. With application of the brand-new anti-counterfeiting construction and verification technical scheme, effective commodity anti-counterfeiting can be realized by effectively utilizing existing resources at low cost through easy operation, multiple times of inspection and multi-channel checking.

Description

technical field [0001] The invention belongs to the technical field of commodity digital anti-counterfeiting, and in particular relates to a commodity anti-counterfeiting code structure and a verification method thereof. Background technique [0002] The importance of anti-counterfeiting is self-evident, so I won't elaborate here. From the perspective of anti-counterfeiting code structure, common anti-counterfeiting methods can be divided into: [0003] 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. [0004] 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 on...

[0004] 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
