Grain and oil food full supply chain information security management system and method based on trusted identifier and IPFS

Abstract

The invention provides a grain and oil food full supply chain information security management system and method based on a trusted identifier and an IPFS, and relates to the fields of block chain technology, grain and oil food security and the like. The system is realized by adopting a browser / server structure, and provides management functions of registration, information acquisition, informationquery, real-time monitoring and the like for a user based on a credible identification model of a block chain and an IPFS + block chain dual-mode storage mechanism. According to the method, the operation process of the grain and oil food full supply chain is analyzed, distributed nodes are set to upload data, a grain and oil food full supply chain credible identification model based on the blockchain is constructed, and a dual-mode data storage mechanism of IPFS and the block chain is adopted. According to the invention, the data transmission of each link on the grain and oil food full supply chain is safe and transparent, the information access speed and privacy protection are improved, the upper and lower chains of the supply chain information are controlled through the intelligent contract, and the management functions of grain and oil food full supply chain information acquisition, query, tracing, monitoring and the like are realized.

Description

technical field [0001] The present invention relates to the fields of block chain technology, grain, oil and food safety, etc., and specifically relates to an information security management system and method for the entire supply chain of grain, oil and food based on trusted identification and IPFS. Background technique [0002] Grain and oil is a general term for cereals, beans and other grains and oilseeds and their processed and semi-finished products, and is a general term for the main food of human beings. The so-called food is the most important thing for the people. Food is a necessity for our human survival and a special commodity related to the national economy and people's livelihood. More attention should be paid to safety supervision. In the whole supply chain of grain, oil and food, there are multiple "stakeholders" who are key transaction participants, such as farmers, production factories, logistics companies, sellers and consumers, with multiple nodes, long ...

AI Technical Summary

Problems solved by technology

At present, the entire supply chain of grain, oil and food has the problem of isolated information islands, the data between each link of the supply chain is opaque, information security management is difficult, and traceability takes a long time
