Block chain-based anti-counterfeiting traceability method and system

Abstract

The invention relates to a block chain-based anti-counterfeiting traceability method and system. According to the method and system, an anti-counterfeiting traceability block chain platform is constructed based on a block chain intelligent contract; a public key and private key pair of each block chain node of the block chain platform is successively generated; the current node writes the related information of a product with a timestamp into a current block based on the private key, writes anti-counterfeiting traceability verification information with a write-in timestamp into the current block based on the public key of the next circulation node; the secondary node reads product related information according to the public key of the previous node and reads the anti-counterfeiting traceability verification information according to the private key of the current node to complete anti-counterfeiting traceability verification of the product; and the above operation is repeated by other nodes, so that an anti-counterfeiting traceability block chain can be constructed. By means of the authority and function of the key pairs generated by the block chain, the problem of information credibility in product anti-counterfeiting traceability can be thoroughly solved, the commercial behavior of each circulation node is standardized, the counterfeit and shoddy problems in the product circulation process are eradicated, and public, transparent, visible and credible product anti-counterfeiting traceability is realized.

Description

technical field [0001] The invention belongs to the technical field of product anti-counterfeiting and traceability, and in particular relates to a blockchain-based anti-counterfeiting traceability method and system. Background technique [0002] At present, the main anti-counterfeiting methods of products are: RFID wireless radio frequency. By affixing a logo with a chip on the product packaging, the relevant information can be automatically collected and read when the product enters and exits the warehouse and transportation, and the flow of the product can be recorded in the On the chip; two-dimensional code, consumers can scan the two-dimensional code through smart phones and other devices, and then they can query the relevant information of the product, and the records of the query will be kept in the system. Accurate recall is achieved; barcode + product batch information, through barcode plus information such as production date, production time, batch number and other...

Problems solved by technology

[0004] In order to solve the problems existing in the existing technology that cannot fundamentally solve the problems of counterfeiting and cheating in circulation links in the whole process of production, transfer, and circulation of products through copying, transferring anti-counterfeiting marks, etc. Interaction, transmission, verification, and tracking of information and anti-counterfeit traceability information, issues such as openness, transparency, credibility, non-tampering, traceability, and traceability of anti-counterfeit traceability information, as well as information, data, digital assets, digital warrants, etc. , anti-counterfeiting and traceability issues such as the interaction of new product types, information and data modification, falsification, and replacement in the process of circulation demand, the present invention provides a method and system for anti-counterfeiting traceability based on blockchain, which has high credibility and openness , transparent, visible, credible, non-tamperable, traceable, traceable, etc. to eradicate product interaction, information and data modification, counterfeiting, replacement, and counterfeit and shoddy problems in the circulation process
