Problems solved by technology

[0003] The existing food and drug traceability system mainly faces problems such as irregular information collection, insecure data storage, vulnerability to central system attacks, and insufficient privacy protection for information exchange between enterprises; the decentralized, distributed, and non-tamperable features of blockchain technology The characteristics of traceability and data traceability can undoubtedly better meet the characteristics of authentic traceability information, reliable storage, and long-term historical preservation required in the construction of food and drug traceability systems. However, traditional blockchain technology lacks all-round and multi-dimensional definitions of traceability objects. , and has a large storage pressure on the chain

Embodiment Construction

[0117] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0118] By using a food and drug supply chain modeling method, the food and drug supply chain process is described in a standardized manner, and the objects in the process are authenticated according to the process of the standardized description, and the objects that pass the verification are stored on the chain. At the same time, the traditional The blockchain storage index is improved to achieve more efficient food and drug traceability. refer to figure 1 As shown, it is a schematic diagram of a blockchain-based food and drug traceability method provided by an embodiment of the present invention.

[0119] In this embodiment, the blockchain-based food and drug traceability method includes:

[0120] S1. Determine the additional relevant information required by different types of enterprises in the food and drug supp...

Abstract

The invention relates to the technical field of blockchains, and discloses a food and drug traceability method based on blockchain, and the method comprises the steps of determining related information required to be added to different types of enterprises in a food and drug supply chain transaction process; obtaining a food and drug supply chain process based on the blockchain by utilizing a blockchain modeling method based on the food and drug supply chain; performing identity verification on participants in the food and drug supply chain; utilizing a blockchain fragmentation load distribution strategy based on blockchain node performance; enabling the blockchain node to perform consensus verification on the data provided by the participants in the food and drug supply chain, and if thedata passes the consensus verification, enabling the blockchain node to store the food and drug data by using a collaborative storage scheme; performing index construction by utilizing an improved blockchain index storage strategy, and realizing index query of food and drug traceability according to the constructed blockchain index. The invention further provides a food and drug traceability system based on the blockchain. According to the invention, traceability of food and drugs is realized.

Description

technical field [0001] The present invention relates to the technical field of block chain, in particular to a method and system for traceability of food and medicine based on block chain. Background technique [0002] With the continuous growth of the economy and the continuous improvement of people's living standards, consumers no longer only pay attention to the basic needs of commodity prices and types when shopping, but pay more attention to the quality and safety of commodities. The pharmaceutical industry and the food industry are directly related to people's lives. Drug safety and food safety directly affect people's life and health. The problem of counterfeit and shoddy medicines and medicines continues to emerge, causing the safety of food and medicines to become a hot topic in society and the focus of people's attention. [0003] The existing food and drug traceability system mainly faces problems such as irregular information collection, insecure data storage, v...
