Agricultural product traceability method and system and data processing server

Abstract

The present application provides an agricultural product traceability method, which includes: storing basic information of a target agricultural product, inspection task information of each stage in aplanting plan, inspection task execution result information of each stage in the planting plan, transportation trajectory information of the target agricultural product, and processing information ofthe target agricultural product into a block chain; generating a unique graphic code for each independent product of the target agricultural product, wherein the graphic code includes the traceability address of the target agricultural product, and the consumer accesses the relevant information of the target agricultural product stored in the block chain by scanning the graphic code. The invention realizes that the whole process data of agricultural products from the seed stage to the final sale to the consumers is stored in the block chain. By utilizing the tamper-proof property of the blockchain, the manager and the consumers can only access the data in the block chain, but can not tamper with the data, thus ensuring the safety and reliability of the data.

Description

technical field [0001] The present invention relates to the field of block chain technology, and more specifically, to a method, system and data processing server for traceability of agricultural products based on block chain technology. Background technique [0002] In recent years, food safety issues have occurred frequently. In terms of agricultural products, the more well-known issues are "stale grain", "aged grain" and "aflatoxin". After special processing and packaging, these agricultural products look similar to new grains, but these grains are harmful to the body, and generally it is difficult for the public to distinguish them. If you go to the manufacturer on the packaging bag, you may not be able to find them, which will eventually affect your health. And no one responsible has been found. [0003] A current solution is to create a traditional relational database that is only used for internal personnel management to store product information of agricultural prod...

AI Technical Summary

Problems solved by technology

The data consumers in this database cannot know, and because it is a traditional database storage method, as long as the access method of the database is mastered, the data can be tampered with

After tampering, it is impossible to accurately know whether the purchased agricultural products are grown on this piece of land, whether the agricultural products corresponding to the data are the purchased farm products, and whether the data nodes are accurate

[0004] Another solution is to implant a special carrier in the seed that does not affect growth and consumption at the seed stage. After purchasing, consumers can use special verification methods to verify whether the purchased agricultural products come from this land. Execution costs are high, resulting in final selling prices that are out of the reach of most consumers
