Blockchain-based poultry supply chain traceability system

Abstract

The invention discloses a blockchain-based meat and poultry supply chain traceability system, which comprises a data acquisition device for acquiring product information and environment information, and a visual interaction device for interacting user information, product information and environment information with a user; a data server which is used for receiving, storing and managing the user information, the product information and the environment information, and a blockchain server which is used for processing and verifying the user information, the product information and the environment information; a data acquisition device which acquires acquired information, the acquired information is displayed through the visual interaction device, the visual interaction device interacts with a user to obtain user information, the visual interaction device sends the acquired information and the user information to the data server for storage and management, and precursor information is verified through the blockchain server; according to the non-centralized data system based on blockchain data storage, the data are more transparent and shared, and the data credibility and the data credibility are improved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a traceability system for meat and poultry supply chains based on block chains. Background technique [0002] With the development of big data, artificial intelligence technology, blockchain and other fields, many fields closely related to people's "food", including agricultural production, breeding, animal husbandry and even the commodity supply chain industry, urgently need new technologies. The integration of technologies to solve the current food safety, food information, agricultural intelligent production and many other problems, but in the process of meat and poultry breeding production supply, the relevant query system is lacking, or the query system adopts the traditional front-end-background and other centralization System design, such a system design structure has problems in data "security", which is in contradiction with the "safe and reliable" food information ...

AI Technical Summary

Problems solved by technology

[0002]With the development of big data, artificial intelligence technology, blockchain and other fields, including agricultural production, breeding industry, animal husbandry and even commodity supply chain industry Many fields closely related to people's "food" also urgently need the integration of new technologies to solve many existing problems such as food safety, food information, and agricultural intelligent production. The system is lacking, or the query system adopts the traditional front-end and back-end centralized system design. Such a system design structure has problems in data "security", which is in contradiction with the "safe and reliable" food information pursued by consumers;

[0003] such as As shown in Figure 1, at present, meat and poultry manufacturers or sellers have their own online sales platform, and the maintenance and management of the system platform are all maintained by the manufacturer or seller independently, or in the form of outsourcing; the operation and maintenance party needs to provide The data center server uploads data, and users access the data content of the system through the front-end. However, there are several problems in this system design and operation mode: first, the system is maintained by the manufacturer or merchant independently, and the information is not disclosed by the system. Merchants manage and update the data, resulting in data that can be tampered with; secondly, the credibility of the system data is insufficient to provide protection for food safety and food information security; finally, the system is a centralized system. Once the data center server has problems or loses operating capacity, Data will be lost and the system will become inaccessible

[0004]On the one hand, in the supply chain, because there may be mutual distrust between various cooperative merchants, and there is no third party that is mutually trusted, merchants and consumers There is also a trust barrier between them. Consumers cannot fully trust merchants, and at the same time they cannot trust merchants' management of data. Therefore, it is necessary to allow consumers to also have the right to join in the supervision of data to improve consumers' trust in merchants and data. In addition, the application of blockchain in other fields cannot solve the special problems in the meat and poultry supply chain, including the fact that consumers are not interested in scanning codes, and cannot realize the authenticity and necessity of information; Merchants bring more sales and business income

[0005]In the previous blockchain traceability systems, information graphic codes such as QR codes and barcodes were usually used as storage carriers for blockchain traceability data. , The barcode can be copied by "copying", etc., so this information storage method is easy to be copied and reused, thus reducing the security of this information storage method

[0006] On the other hand, the elderly population in my country currently accounts for about 60% of the total population, and the penetration rate of smartphones in my country is about 70%, while the smartphone usage rate of the elderly is only about These data show that for most people, it is very difficult to use mobile phones to scan codes and trace the source in popularization and operation, especially for some elderly people or remote areas. It is very good to use mobile phones to scan codes and other traceability operations. It will still take a long time to solve this problem from the crowd itself
