Agricultural product supply chain traceability system based on internet of things and block chain

Abstract

The invention discloses an agricultural product supply chain traceability system based on the internet of things and a block chain. The system comprises an internet-of-things module for carrying out unified standard collection on body information and activity information corresponding to an agricultural product at all links of an agricultural product supply chain, a checking module for packaging the body information and activity information, collected by the internet-of-things module, of the agricultural product into blocks and carrying out information effectiveness verification, a block chain module for storing blocks with successful verification by the checking module, and a tracing module being connected with the block chain module and being used for information tracing. During the information collection process, data exchange and understanding of all links of a supply chain are realized conveniently by using a unified standard. The block chain module stores related data information of the agricultural product, so that the system becomes a decentration platform; and thus modification of the traceability system data is not affected by tampering of tracing information by any link of the supply chain, so that a tracing objective is achieved. Therefore, data security and reliability of the overall network of the agricultural product supply chain can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of traceability of agricultural products, in particular to an agricultural product supply chain traceability system based on the Internet of Things and blockchain. Background technique [0002] With the improvement of people's income level and the change of consumption concept, the quality and safety of agricultural products have attracted more and more attention from consumers. However, the quality and safety situation of agricultural products in China is becoming more and more serious, and the quality and safety incidents of agricultural products break out frequently, which not only affects people's health and life safety, but also affects the economic interests of enterprises and the country, and the sustainable development of agriculture. The occurrence of agricultural product quality and safety issues involves all links in the supply chain, including suppliers, producers, and sellers. [0003] In order...

Problems solved by technology

However, the traceability system based on the Internet of Things relies on the agent communication mode or the server / client mode. All devices need to be verified through the connection of the centralized cloud server. Factors (disasters, hackers) cause data damage, loss, and tampering, so it is difficult to achieve effective traceability and lack of credibility
