The embodiment of the invention provides a product traceability method and device based on a block chain, and belongs to the technical field of traceability. A commodity production main body initiatesa digital certificate issuing request and an anti-counterfeiting authentication request based on a target commodity, and a commodity service main body confirms the digital certificate issuing request; a digital certificate is generated by adopting a specific algorithm according to the digital certificate issuing request; a graphic code is generated based on the anti-counterfeiting authenticationrequest after an anti-counterfeiting authentication agency passes checking; the commodity production main body, the commodity service main body and the anti-counterfeiting authentication agency sign the digital certificate and the graphic code and broadcast the digital certificate and the graphic code to a block chain; and a verifier acquires the anti-counterfeiting traceability information of thetarget commodity through the graphic code for verification, and traceability and non-artificial tampering of a commodity source and important links of products are ensured through authentication of the digital certificate and the plurality of participants.
Description
technical field [0001] The present invention relates to the technical field of information traceability, in particular to a blockchain-based product traceability method and device. Background technique [0002] With the development and popularization of computer technology and big data processing technology, more and more transactions such as shopping, obtaining information, and paying bills are performed online in daily life. Human beings use the Internet more and more to shop, but consumers do not know whether the products they buy are safe and qualified. Food, medicine, cosmetics and other products will go through many links in the transportation process from the manufacturer to the consumer. The quality of the product will directly affect the health of the consumer. cause irreversible effects on health. [0003] With the development of blockchain technology, more and more blockchain services have entered the market. How the blockchain can ensure the traceability of th...
