Commodity anti-counterfeiting code generation system based on block chain

Abstract

The invention provides a commodity anti-counterfeiting code generation system based on a block chain in the field of anti-counterfeiting codes. A layer of public information and a layer of anti-counterfeiting verification information are generated by using duplex anti-counterfeiting technology, and the anti-counterfeiting verification information is invalid after one-time verification, so that anti-counterfeiting cannot be copied, a real anti-counterfeiting effect is achieved, meanwhile, an anti-counterfeiting code cannot be copied, the verification code contains specific information of a commodity, and anti-counterfeiting is safer; verification information is verified through a public block chain, meanwhile, the verification process needs to be photographed and stored for the first time,and photographing information is returned to the public block chain to serve as a return result of subsequent verification, so that an anti-counterfeiting code cannot be copied, and a real anti-counterfeiting effect is achieved. Meanwhile, the true and false verification information is generated by using a chaotic equation, so that repeated true and false verification information is avoided.

Description

technical field [0001] The invention relates to the field of anti-counterfeiting codes, in particular to a block chain-based product anti-counterfeiting code generation system. Background technique [0002] In today's society, counterfeit goods are prevalent, counterfeiting has become a flooding trend, and food and drug safety accidents occur frequently. How to realize anti-counterfeiting of commodities, eliminate counterfeiting, recover the economic losses of the country and enterprises, and protect the rights and interests of consumers is a global issue that urgently needs to be studied and solved. The problem. The existing digital anti-counterfeiting technology basically uses a pseudo-random sequence or an ordered serial number to generate an anti-counterfeiting code through DES symmetric encryption, which has a certain gap with the performance requirements of "unforgeability and uniqueness" of the anti-counterfeiting code in digital anti-counterfeiting technology. ; The...
