Commodity composite anti-fake code and symmetric test anit-fake method

Abstract

The commodity anti-fake method includes two parts: method of creating composite commodity anti-fake code and method of verifying commodity anti-fake code. The composite commodity anti-fake code includes two digital codes of main commodity anti-fake code MZ and auxiliary commodity anti-fake code MF. The MZ consists of prefix code ZK0, function code ZK1 and base number code ZK2; and the MF consists of prefix code FK0 and calculation value code FK1. ZK1 corresponds to on unique function fZK1 (x) in the given function library CFDB, and FK1 belongs to function code library CFC and fZK1 (ZK2). The two anti-fake codes are printed on commodity before delivery; and during verification, MZ and MF are read out to distinguish ZK1, ZK2 and FK1, search fZK1 (x) and verify fZK1 (ZK2)=FK1 for checking the truth of the commodity.

Description

[0001] The invention is a method for commodity anti-counterfeiting, which includes two parts: a method for generating composite anti-counterfeiting codes for commodities and a method for verifying the anti-counterfeiting codes for commodities. technical field

[0002] The invention belongs to the technical field of commodity digital anti-counterfeiting. Background technique

[0003] The proliferation of counterfeit and shoddy goods is a prominent problem in my country's economic life. Cracking down on the production and circulation of counterfeit and shoddy goods is related to purifying the order of circulation, protecting consumers' rights and interests, and protecting legal intellectual property rights. It is also directly related to improving the reputation of our country's goods in the international market. relevant. Using information technology to establish an effective and easy social commodity anti-counterfeiting system is a technical and social project that needs to b...
