ABSTRACT
With the development of the economy and the improvement of people's quality of life, the public demand for food taste has gradually changed to the demand for food safety. In order to better facilitate the government to strengthen food safety supervision and protect people's food safety, it is necessary for the government to realize information interaction with enterprises related to the food supply chain and ensure the traceability of food flowing into the market by exchanging and sharing the data of food safety information. With the rapid promotion and popularization of various mobile terminals in the Internet era, the data analysis technology based on artificial intelligence technology is more accurate, which makes the value contained in the data more and more important to people. At present, many fields need the opening and sharing of big data, but there is no reliable data sharing environment in the field of food supervision, and it is still difficult to ensure the traceability of data related to food safety. Blockchain has unique advantages of decentralization and distribution, which can help break the current obstacles of big data sharing and exchange and achieve a high degree of data sharing, interconnection and exchange. Based on the blockchain technology, this paper studies the food safety data sharing and exchange mechanism, combines the blockchain with the distributed file system, constructs the data connection model, stores the shared information on the blockchain, then introduces IPFs and zigzag coding, designs the corresponding control method, and establishes a reliable data sharing and exchange mechanism. The analysis shows that the data sharing and exchange mechanism proposed in this paper can meet the needs of food safety data sharing and exchange.
