Product traceability authentication method and system based on alliance chain

Abstract

The invention provides a product traceability authentication method and system based on an alliance chain, and relates to the technical field of block chains, and the method comprises the steps: storing the encrypted traceability information and consumer comment information of a whole process of a product, and storing the hash of the encrypted traceability information and the hash of the consumer comment information to the alliance chain; querying a traceability body according to the unique identifier ID of the to-be-authenticated product, and calling platform party authentication operation and consumer authentication operation in the traceability body; the platform side performs authentication operation to obtain each attribute value in the traceability body and the hash value of the encrypted traceability information of each process of the to-be-authenticated product, and compares with each corresponding attribute value in the traceability body to obtain a platform side authentication result; and the consumer authentication operation obtains the hash of the consumer comment information, further obtains the consumer comment information of similar products, obtains a consumer authentication result, and further obtains a final authentication result of the to-be-authenticated product. According to the invention, the platform-side authentication process is separated from real data, and the security and credibility of platform-side authentication and consumer authentication are ensured.

Description

technical field [0001] The invention relates to the technical field of blockchain, and relates to a product traceability authentication method and system based on a consortium chain. Background technique [0002] With the development of the social economy, the commodity market is becoming more and more prosperous.
