The invention is applicable to the technical field of block chains, and provides a blockchain electronic tag device and a product traceability authentication system, the blockchain electronic tag device comprises an acquisition unit used for acquiring user identity information and sending the user identity information to a control processor; a storage unit which is used for generating a key fieldaccording to the product traceability data information stored in the background server and storing the key field; and a control processor which is used for generating a blockchain electronic tag according to the product traceability data information, the user identity information, the dynamic identification information and the preset verification mode information, so that the user obtains the product traceability data information according to the blockchain electronic tag. The method is applied to the field of traceability authentication, authenticity, effectiveness, instantaneity and safety of traceability authentication in the production process of products can be guaranteed, interference of human factors is avoided to the maximum extent, and therefore the phenomenon of 'shiny-leaved yellowhorn wearing' is avoided fundamentally, and higher safety experience is provided for users.
Description
technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a block chain electronic tag device and a product traceability authentication system. Background technique [0002] At present, the mainstream traceability authentication methods on the market mostly use QR codes or other forms of electronic tags (standard electronic tags with antennas, chips, and storage), but there is a problem with many of them. In such a situation, it is difficult to completely eradicate counterfeiting and shoddy products, that is, it is impossible to track the entire process, thus leaving more space for counterfeiting and making room for counterfeiting. Simply using the two-dimensional code method provides counterfeiters with a larger and broader counterfeiting space, making traceability become empty talk; in addition, it is difficult to fundamentally guarantee the authenticity and effectiveness of the product with a single electronic label ...
