Large agricultural product traceability management system based on block chain technology

Abstract

The invention discloses an agricultural product traceability management system based on a block chain technology. The agricultural product traceability management system comprises a management node, an agricultural product benefit related party node and a block chain management and block chain traceability subsystem. The management node is a platform root node, and the agricultural product benefitrelated party node is a collaborator and is responsible for uploading related process tracing data; the management node is in point-to-point connection with each agricultural product benefit relatedparty node through a P2P network. The block chain management subsystem is deployed on a management node server and is used for key management, node addition, data uploading and data retrieval; the block chain traceability subsystem is used for uploading data, generating a two-dimensional code and retrieving the data; the secret key management adopts an asymmetric secret key management system and is used for generating a pair of secret key public key and private key for the newly added node, and the public key is used for encrypting data and verifying signatures; and the private key is used fordecrypting the data and the personal signature. According to the agricultural product traceability management system, data cannot be tampered, the system is complete and real, and the trust problem of agricultural product traceability can be solved.

Description

technical field [0001] The invention belongs to the technical field of traceability of agricultural products, and in particular relates to an agricultural product traceability management system and method based on block chain technology. Background technique [0002] With the development of social economy, people pay more and more attention to the quality and safety of agricultural products, and the traceability system of agricultural product quality came into being, which played a certain role in solving the crisis of trust in the quality and safety of agricultural products. However, in the traditional agricultural product quality traceability management, stakeholders in the agricultural product industry chain build their own systems according to their own business processes, and the data is stored in a centralized manner. This will cause the following problems: [0003] There is a single point of failure in the data, that is, it is very dangerous for the data to only exist...

AI Technical Summary

Problems solved by technology

[0003] There is a single point of failure in the data, that is, it is very dangerous for the data to only exist in one central node server. When the node's own database is damaged, the system service will be interrupted. If the data is not backed up in advance, the data will be lost;

[0004] The ability to read and write concurrently is low, that is, all requests are centralized to the central node for interaction, and a sudden increase in user requests will cause the central node to go down;

[0005] The amount of traceable information is limited, that is, the traceability of agricultural products involves a long industrial chain, including growers, agricultural material manufacturers, processing plants, testing agencies, sellers, logistics and warehousing, etc. The information displayed by the traceability query terminals of most systems is also It only involves the information of agricultural producers, and cannot realize the traceability based on the production, processing, sales and circulation of the agricultural products, and cannot realize the whole process of information traceability "from the field to the tip of the tongue";

[0006] Data inconsistency, that is, in the traceability process of agricultural products, the data generated by all relevant parties are stored in their own databases, and there is no unified agricultural product ID, which is prone to data inconsistency;

[0007] The authenticity and reliability of the data are poor, that is, the relevant parties of agricultural product traceability may have fraudulent behaviors of tampering and forging data at will according to the principle of maximizing their own interests, resulting in a crisis of trust among relevant parties

[0008] The above problems will seriously affect the quality and safety of agricultural products and the interests of all parties in the agricultural product industry chain, and ultimately threaten the health of consumers
