Abstract

The invention discloses a data traceability system based on a block chain, and the system comprises a data module which collects data, stores the collected data to the block chain, and transmits a block chain identification request and an intelligent contract request at the same time; a client module is used for receiving the blockchain identification request, identifying the blockchain and outputting an identification result; a server module used for executing reading and writing of the data stored in the block chain and performing data verification and data reading and writing on the data through the intelligent contract request; a data traceability query system used for sending a data query request to the client module and acquiring data required to be queried from the client module; and an interface service module used for realizing data transmission between the data module and the client module and data transmission between the data traceability query system and the client module.By adopting the technical scheme, the uplink storage of the specified field data of the service system is realized; automatic collection is achieved, and automatic chaining of designated fields of adesignated table of a designated database is achieved in a database log mode.

Description

technical field [0001] The invention relates to the technical field of data processing, and specifically refers to a blockchain-based data traceability system and method thereof. Background technique [0002] The product traceability system is widely used in food, medicine, clothing, electronics, fishing boats and other industries. Once there is a problem with the quality of the product on the consumer side, the traceability code on the product label can be used to conduct online inquiries to find out all the circulation information such as the manufacturer of the product, the place of origin of the product, and the specific operator, so that the entire production and operation of the product Activity is always under active monitoring. [0003] At present, there are many ways to trace the product on the market, but most of the traceability methods are to directly extract part of the data from the database as the traceability data by scanning the QR code. This method has two...
