Problems solved by technology

Second, due to the use of asymmetric encryption algorithms and hash algorithms, the tampering of the data of a single node will lead to the modification of the data of other nodes on the blockchain, and the workload is too large for the system to bear, so the modification of the database by a single node is invalid, ensuring The recording and transmission of data is reliable and cannot be tampered with
[0006] 1. If the traceability information of each agricultural product is stored in the public chain, the overhead of calling smart contract storage is too high;
[0007] 2. In the public chain, it is difficult to serialize and store the traceability information of different formats and sizes, the storage efficiency is low, and the amount of information storage is small;

Embodiment 1

[0037] Example 1: Architecture design of agricultural product traceability system

[0038] The agricultural product traceability system architecture includes the physical layer, data layer, network layer, consensus layer, incentive layer, contract layer, and application layer. figure 2 Shown.

[0039] The physical layer is the physical data collected in each production link of agricultural products through the Internet of Things technology. The data collection of the Internet of Things involves sensors, RFID, two-dimensional codes and real-time positioning technology, using temperature / humidity sensors, image capture cards, pressure sensors, RFID reader and QR code reader equipment are completed.

[0040] The data layer includes the communication architecture of the Internet of Things and the blockchain structure. The communication architecture of the Internet of Things uses a 5G communication network to ensure the real-time upload of massive data collected by the physical layer. T...

Embodiment 2

[0046] Embodiment 2: Traceability information storage and query steps

[0047] The information storage in the traceability system adopts the form of "Internet of Things + Blockchain", and the blockchain adopts the structure of "Private Chain + Public Chain" to ensure efficient information storage and cannot be tampered with. Where C 1 Represents the production base of agricultural products;

[0048] C 2 Represents a warehousing company;

[0049] C 3 Represents the brand / processing company;

[0050] C 4 Represents an e-commerce platform;

[0051] QC means traceability information query module;

[0052] P represents a certain agricultural product;

[0053] PrB stands for private chain;

[0054] PuB stands for public chain;

[0055] M i Indicates the detailed information of the i-th business link of agricultural products;

[0056] S i Represents the digital signature of the i-th business link of agricultural products;

[0057] H i Represents the hash value of the i-th business link of agricultu...

Embodiment 3

[0078] Embodiment 3: Encryption steps of traceability information

[0079] (1) The certificate center uses an asymmetric encryption algorithm to generate a pair of public key and private key addresses for each block of agricultural products, uses the master public key address to send a message to the new public key address, and generates a new block to write to the private chain , Complete the registration of the agricultural product;

[0080] (2) Enterprises in each business link involved in agricultural products use their private key addresses to digitally sign the production information, and use the public key addresses of the companies in the private chain to verify the electronic signature. The verified data is legal and can be stored To the private chain;

[0081] (3) Use the hash algorithm to calculate the production information uploaded by each company and the hash value of the digital signature as the tag information, and then use the tag information as the script informati...

Abstract

The invention provides an agricultural product traceability system based on a block chain. The system comprises an agricultural product big data platform, an agricultural product traceability query platform, and a 5G network; the agricultural product big data platform comprises an agricultural product growth information module, a storage information module, a processing information module and a sales information module; the agricultural product traceability query platform comprises a data restoration module, an anti-counterfeiting query module and a traceability information query module; and each module carries out data uploading and traceability query through a 5G network. According to the invention, further optimization is carried out on the basis of a traceability system based on a block chain; an agricultural product tracing system combining the advantages of a private chain and a public chain is designed. On the basis of preventing the agricultural product information from being attacked and tampered, the certified product label is further prevented from being stolen and copied, the data storage efficiency is improved, the calculation expenditure is reduced, and consumers or supervision departments can quickly position production links and responsible persons of problematic agricultural products.

Description

Technical field [0001] The present invention relates to the field of agricultural product traceability systems, in particular to an agricultural product traceability system using blockchain technology. Background technique [0002] With the continuous growth of consumers' consumption level of agricultural products, people have higher and higher requirements for the quality and safety of agricultural products. In order to solve the supervision of agricultural product quality and safety, it is particularly necessary to establish a reliable and transparent agricultural product traceability system. For the regulatory authorities, when an agricultural product safety incident occurs, the agricultural product traceability system can quickly query detailed information about the entire process of agricultural products from production, storage, processing to sales, and accurately identify the problematic link and responsible party, so as to improve the quality of agricultural products. And...
