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

Embodiment Construction

[0071] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0072] Through the three "distributions" of distributed bookkeeping, distributed communication, and distributed storage.

[0073] The method of the blockchain is to innovate the structure of the database and divide the data into different blocks. Each block is linked to the back of the previous block through specific information, and it is connected sequentially to present a complete set of data. The data in the block is permanently stored in the form of electronic records. The blocks are generated one by one in chronological order. Each block records all the value exchange activities that occurred during its creation. All ...

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...
