Agricultural product authentication traceability method based on block chain

Abstract

The invention discloses an agricultural product authentication traceability method based on a block chain. The method comprises the following steps: S1, performing identity registration and login at an agricultural product traceability system registration terminal through a producer; s2, performing agricultural product information uplink operation through the logged-in producer, and obtaining a tracing code of the agricultural product; s3, verifying the agricultural product information through the consumer according to the tracing code of the agricultural product, and completing the agricultural product authentication tracing process based on the blockchain. According to the agricultural product authentication traceability method, consumers do not need to worry about tampering of information in an agricultural product traceability system; a user can use the agricultural product traceability code to carry out related authentication and transaction on a super account book terminal and amobile terminal deployed in a public environment; and the risk that the enterprise data of the producer is easily tampered can be effectively prevented, the safety of the traditional centralized traceability system is greatly improved at a relatively low cost, and convenience is provided for tracing after the server is discovered to be tampered.

Description

technical field [0001] The invention belongs to the technical field of traceability of agricultural products, and in particular relates to a blockchain-based authentication traceability method for agricultural products. Background technique [0002] In recent years, with the improvement of living standards, more and more attention has been paid to the safety of agricultural products, and traceability of agricultural products has become an effective way to ensure the safety of agricultural products. At present, there are many new traceability systems based on electronic tags and QR codes as data carriers. These existing systems have solved the problems of data update, anti-counterfeiting and efficiency to a certain extent, but they are still an extension of the traditional centralized traceability system. These systems are still an isolated island of information, and problems such as immutability, difficulty in sharing and tracing of data still exist. At the same time, rega...

These systems are still an isolated island of information, and problems such as immutability, difficulty in sharing and tracing of data still exist

At the same time, regarding the traceability method of agricultural products currently used by consumers, consumers are still worried that the information obtained through traceability has been tampered with by sales companies, and the information security of agricultural products cannot be guaranteed.

The current agricultural product traceability system is aimed at the data center, which is prone to information tampering, and it is difficult to prevent the risk of internal tampering, and the security is poor
