Example Embodiment

[0026] Example 1

[0027] reference figure 1 ,Such as figure 1 As shown, a food and drug traceability system based on blockchain includes:

[0028] Information recording module: In the links of food and drug production, shipment, and distribution, blockchain is introduced to record the operation information of these important links;

[0029] Data on-chain module: use signature and encryption technology to record the content, call blockchain smart contracts to realize blockchain data on-chain, synchronization, and consensus, eliminating human intervention;

[0030] Retrieval module: scan the food and drug anti-counterfeiting QR code, call the blockchain data retrieval service, and retrieve the traceability information on the blockchain;

[0031] The information recording module is the entry point for business data on the chain. At these entry points, the core and important on-chain data information is recorded to provide a data source for the data on-chain module; the data on-chain modul...

[0032] Example 2

[0033] reference figure 2 ,Such as figure 2 As shown, a blockchain-based food and drug traceability method includes the following steps:

[0034] S1, the information recording module introduces blockchain in the links of food and drug production, shipment, and distribution, and records the operation information of these important links;

[0035] S2, the data on-chain module uses signature and encryption technology for the recorded content, and calls blockchain smart contracts to realize blockchain data on-chain, synchronization, and consensus, eliminating human intervention;

[0036] S3, the retrieval module scans the food and drug anti-counterfeiting QR code, calls the blockchain data retrieval service, and retrieves the traceability information on the blockchain.

[0037] The step S1 is specifically: the information recording module introduces the blockchain in the links of food and drug production, shipment, and distribution, records operation information in th...

Abstract

The invention discloses a food and medicine tracing system and method based on a block chain, and the method comprises the following steps: S1, enabling an information recording module to introduce the block chain in links of food and medicine production, shipment and distribution, and recording the operation information of the important links; S2, the data chaining module calls a block chain intelligent contract to realize the chaining, synchronization and consensus of the block chain data by adopting a signature and encryption technology, and eliminates the human intervention; And S3, a retrieval module which scans the food and drug anti-counterfeiting two-dimensional codes, calls a block chain data retrieval service and retrieves traceability information on the block chain. The invention discloses a food and medicine tracing system based on a block chain, and aims to solve the problem of how to ensure traceability of important links of food and medicine and cannot be tampered manually.

Description

technical field [0001] The invention relates to a block chain, in particular to a block chain-based food and drug traceability system and method. Background technique [0002] At present, the blockchain adopts P2P network technology, asymmetric encryption technology, and uses the blockchain linked list method to store data, which has the characteristics of non-tampering and non-repudiation. The phenomenon of counterfeit and shoddy food and drugs is relatively common, especially once drugs appear, they will cause serious social impact and cause hidden dangers to the lives of the people. How to ensure that the important links of food and drugs are traceable and cannot be tampered with is an important problem facing the current traceability system. Contents of the invention [0003] Aiming at the above problems, the present invention provides a blockchain-based food and drug traceability system and method. [0004] According to one aspect of the present invention, a blockch...
