Safe and trusted block chain of data in traceability system and management method

Abstract

The invention belongs to the technical field of agricultural product data processing, and discloses a safe and trusted block chain of data in a traceability system and a management method, wherein a user layer is a user-oriented interface and performs human-machine interface information interaction with agricultural product consumers; the user layer outputs the block chain service to other resource layers; a management/service layer provides uniform access and management service of nodes of participant parties of agricultural product traceability; a core layer is the core functional layer of the block chain system and provides reliable and efficient service capability for the safety traceability system; a basic layer provides the basic operation environment and components required by normal operation of the block chain system; a cross-layer functional layer provides service for the communication and infrastructure of the agricultural product traceability system. The system transplant the secure communication systems of the block chain into a platform and allows for faster and more transparent information sharing. The specification information communication is the encryption mechanism of strong security, and the asymmetric encryption system/public key system is used to ensure the information interaction security.

Description

technical field [0001] The invention belongs to the technical field of agricultural product data processing, and in particular relates to a safe and trustworthy block chain and a management method for data in a traceability system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] (1) The current traceability system of agricultural products does not have a unified certification standard. In various traceability systems, due to the different authorities, traceability systems, and supply links, there is no unified coding system in China, and it is difficult to realize the integration of the entire supply chain. Traceability. [0004] (2) The current agricultural product traceability system data storage is a three-tier structure B / S mode. According to the data table to be created to maintain the business layer and data exchange layer, the relational or non-relational database is adopted, and people hand o...

AI Technical Summary

Problems solved by technology

[0005] (3) The current agricultural product traceability system relies on the guarantee or guarantee of a third-party organization

[0010] (2) The transparent ledger and its integrity accounting guarantee mechanism are poor. For consumers, transparent ledger means that consumers can see the complete data recorded by the participants in each link

[0012] (3) The existing technology does not use the data distribution storage chain technology to ensure the authenticity and robustness of traceability data

[0014] (4) Poor security of traceability database of agricultural products

The existing technology has not transplanted the secure communication system of the blockchain into the platform, and cannot achieve faster and more transparent information sharing
