Description
Technical Field
The invention belongs to the technical field of food safety, and particularly relates to a food safety tracing system and method based on a block chain.
Background
The food safety problem is a system problem, the design is wide, and the solving difficulty is high. In the traditional tracing, no matter the encouragement of the country or the effort of enterprises, the biggest problem in food tracing and anti-counterfeiting cannot be solved, namely, who provides information with public credibility. The current food tracing technology is mainly based on: the information in the package, the certificate, the EAN.UCC bar code (or two-dimensional code, three-dimensional code) or the radio frequency identification technology (RFID) is used for realizing record inquiry, and the recorded content comprises the information of the producing country of the food, the producing manufacturer (address, contact way), the name, the production batch, the production date, the quality guarantee period, the inspection and the like. The traditional traceability method has many defects, firstly, the traditional traceability method is a centralized storage mode, and in the mode, who maintains the ledger as a center becomes a key of the problem. Whether the source enterprise is stored or the channel provider is stored, since the enterprise is a profit related party on a circulation chain, when the account book information is unfavorable, the enterprise is likely to choose to tamper the account book or lie the account book information is lost due to technical reasons, and the traceability process is invalid. Secondly, the traditional source tracing adopts an information isolated island mode, and under the information isolated island mode, each participant in the market maintains an account book by self, and the account book is commonly called a standing book and is covered with the name of a purchase, sale and inventory system after electronization. Whether the system is an entity standing book or an electronic purchase-sale-stock system, the owner can tamper or centrally compile afterwards as desired. Thirdly, since the conventional food production circulation process is almost in a closed state, malignant channel conflict frequently occurs due to low information circulation, and the benign development pattern of the market is influenced.
The most fundamental purpose of tracing is to perform authenticity identification of food, which essentially establishes trust of consumers on food quality, and a block chain establishes a digital trusted system for helping tracing. In order to solve the pain point caused by the traditional tracing method, the characteristics of data that cannot be tampered, can be completely traced and the like are realized by the block chain technology through technical means such as a timestamp and a consensus mechanism, so that the problem of centralized data storage can be effectively solved, meanwhile, technical support is provided for the establishment of a cross-organization tracing system, an information isolated island is broken, and the problem of business competition caused by malicious goods fleeing is prevented, so that a food safety tracing system and a method based on the block chain are needed.
