Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product quality traceability systems, and in particular to a blockchain agricultural product traceability system based on target identification. Background Art

[0002] Food is the primary need of the people, and agricultural products, as the raw materials of food, are particularly important for their safety. With the rapid development of society, some safety issues related to the agricultural product production chain have gradually been exposed, such as excessive pesticide residues on vegetables, "stale grain" stored for too long, etc., which pose a threat to people's health and life safety. These agricultural products are harmful to the human body, but it is difficult for the general public to identify them, and once food safety problems occur, consumers cannot even find the person in charge.

[0003] Although there are many effective methods or standards for controlling food safety, including ISO9000 certification, GMP (Good Manufacturing Practice), SSOP (Standard Sanitation Operating Procedure), HACCP (Hazard Analysis and Critical Points System) and other effective management methods for controlling food safety, and they are used in practice, these standards are all for controlling specific links, lacking technical means or specifications to connect the entire supply chain. Once a problem occurs in a certain link, the above methods are not perfect in order to find the source of the problem or find all product information related to the problem.

[0004] At present, as consumers pay more and more attention to the safety of agricultural products, some large supermarkets and agricultural product manufacturers have begun to launch agricultural product traceability systems. However, these traceability systems have a small scope of application, and the information of agricultural products is single. The data of agricultural products can be easily tampered with, which has data security issues, reduces the credit of data and the credibility of supervision, and cannot meet the needs of consumers. In addition, most of the existing traceability systems that use blockchain for data storage store all data on the chain, which requires the blockchain to have a large storage space, which is easy to cause a waste of resources. Summary of the invention

[0005] The purpose of the present invention is to provide a blockchain agricultural product traceability system based on target identification, which is convenient for consumers to accurately understand the detailed information of the entire process of agricultural products from sowing to sales by scanning the code, and has high information security. It can also effectively reduce the storage data on the blockchain and effectively save the storage space of the blockchain.
