Abstract

The embodiment of the invention provides a food safety public query system based on a block chain, and the system comprises a data collection module which is used for collecting basic data of a presettype of a tested food, carrying out the encryption of the basic data, generating encrypted basic data, and sending the encrypted basic data to a mobile terminal; a mobile terminal which is used for receiving the encrypted basic data sent by the data acquisition module and sending the encrypted basic data to the main block chain; a main block chain which is used for receiving the encrypted basic data sent by the mobile terminal and storing the encrypted basic data in a block of the main block chain; and a detection terminal which is used for extracting the encrypted basic data from the block of the main block chain, decrypting the encrypted basic data, determining the quality data of the detected food according to the decrypted encrypted basic data, and sending the quality data to the corresponding block of the main block chain. The food safety is detected by using the block chain technology, so that the detection process consumes a time end and is convenient, and the detection resultis reliable.

Description

technical field [0001] This application relates to the technical field of block chain, in particular to a public food safety inquiry system based on block chain. Background technique [0002] Blockchain is a new type of decentralized protocol, which can safely store digital currency transactions or other data. The information cannot be forged and tampered with. The transaction confirmation on the blockchain is completed by all nodes on the blockchain. The consensus algorithm To ensure its consistency, a public ledger is maintained on the blockchain to store the accounts of all users on the blockchain network. The public ledger is visible to any node on the storage block, thus ensuring that it cannot be forged and tampered with. With the development of blockchain technology, the application of blockchain in various fields is becoming more and more extensive. [0003] my country is the world's largest food market. With the continuous improvement of people's living standards, ...
