Grain and oil quality safety credible traceability method based on block chain and identifier analysis

Abstract

The invention provides a grain and oil quality safety credible traceability method based on a block chain and identification analysis, and relates to the fields of block chains, industrial internet identification analysis, grain and oil food safety and the like, and the method specifically comprises the steps: constructing a supply chain composed of planting, processing, warehousing, logistics and sales for a certain grain and oil food product S, recording the information of each link, and storing the information of each link; the block chain is uploaded after verification by using the smart contract; then, based on an industrial internet identification analysis technology, respectively generating an identity identification code corresponding to each link by utilizing the information of each link of the product S; in the circulation process of the product S in the supply chain, the quality supervision department and the consumer scan the identity identification code corresponding to each link, analyze the identity identification code and compare and inquire whether the product S is safe or not; and finally, based on the block chain and identifier analysis, safe and credible traceability of the product S is realized. According to the invention, the security and transparency of data are realized, and the collection, query, tracing and monitoring of enterprise information in each link of the grain and oil food supply chain are realized through the smart contract.

Description

technical field [0001] The invention relates to the fields of block chain, industrial Internet logo analysis, grain, oil and food safety, etc., and specifically relates to a reliable traceability method for grain and oil quality and safety based on block chain and logo analysis. Background technique [0002] Grain products include rice, corn, wheat, soybeans and their finished products, etc. Oily foods include palm oil, soybean oil, rapeseed oil, corn oil and other oils, etc., which are essential products needed in the lives of Chinese residents. The safety of supply is of great significance to the life and health of the people and the harmonious development of society and the country. [0003] At present, the main shortcomings of information traceability in the grain, oil and food supply chain are: [0004] 1. There are many types of grain and oil products and a large amount of traceability data [0005] The general traceability of the food supply chain is: to trace the...
