Problems solved by technology
The current food industry has problems such as information asymmetry and poor data credibility caused by high-value information being controlled by a small number of institutions, selective disclosure, shielding, or tampering.
Due to the lack of high-quality original information, information asymmetry, and poor reliability in the existing technology, the conventional food quality and safety management traceability system has defects such as high cost, low efficiency, and difficulty in quickly and accurately discovering and controlling the source of hazards.
The industry lacks a unified and authoritative regulatory platform and an efficient and reliable traceability system

Embodiment Construction
[0019] In order to facilitate the understanding of the present invention, the present invention will be understood in connection with the accompanying drawings and examples, and the embodiments described herein are not intended to illustrate and explain the present invention. this invention.
[0020] A food rapid traceability system of a multi-chain interconnected zone link network, including a food fully industrial chain production data acquisition subsystem, stores a cloud data base of production data, and stores a block chain network for producing data check information.
[0021] The cloud database of the present embodiment is a multi-copy, distributed stored cloud database for storing food industry chain holographic production data; the same batch of data has the same data ID in the cloud database and blocks, data and districts in the cloud database The blocks on the block chain network are associated with each other through the data ID.
[0022] The block chain network of the...

The invention discloses a food rapid traceability system and method based on a multi-chain interconnected block chain network. The traceability system includes a production data acquisition subsystem of the entire food industry chain, a cloud database for storing production data, and an area for storing production data verification information. block chain; the method includes: scanning the two-dimensional code of the product with a scanner to obtain the traceability hyperlink address and the chain number and the block number of the corresponding block of the product; the scanner sends the chain number and the block number to the Traceability system; the traceability system uses the binary search method to find the corresponding block on the blockchain network through the chain number and block number; decrypts the block information to extract the associated information and data verification information of the cloud database; through the associated information with the cloud database and The data ID looks up the production data in the cloud database, and uses the verification information to check whether the data has been tampered with; repeat the above steps, trace the source forward in turn according to the source data ID in the block, until the source data ID is 0, the trace is completed, and the trace result is returned .
Description
Technical field [0001] The present invention belongs to the field of block chains, involving a fast traceability system and method, particularly involving a fast traceability system and method of food-based network based on cloud database and multi-chain interconnected zone. Background technique [0002] Food quality safety is closely related to people's healthy life and social stability. The current food industry has problems such as information asymmetry, data reliability, and data credibility, such as a minority, selective disclosure, shielding or tampering. Since there is a problem of less original information, information asymmetry, reliability difference, etc. The industry lacks uniform, authoritative regulatory platform and efficient, reliable traceability system. Inventive content [0003] In view of the problems in the current food industry and the defects of the prior art, the present invention provides a set of food safety traceability systems that combine data tamper...
