Cross-department data sharing system and method based on block chain technology

Abstract

The invention relates to a cross-department data sharing system and method based on a block chain technology, the system comprises a query server, a sorting node and a plurality of department storage centers, in each department storage center, a data acquisition module is connected with a data processing server, the data processing server is connected with a distributed storage system and the query server, and the distributed storage system is connected with the query server; and the data processing server is used as a peer node of the block chain, and the sorting node performs information transmission with each department storage center through a message channel. Compared with the prior art, through the blockchain technology, the structured data is directly uploaded and stored, it can be guaranteed that the data cannot be tampered, the original hash value of the unstructured data is uploaded and stored, hash value verification is carried out during subsequent data query, tracing can be carried out, the behavior of tampering the data is further limited, and the security and credibility of the data sharing system are improved.

Description

technical field [0001] The present invention relates to the field of data sharing, in particular to a cross-departmental data sharing system and method based on block chain technology. Background technique [0002] With the continuous advancement of science and technology, more and more attention has been paid to the construction of smart cities. To put it simply, the construction of smart cities is to combine traditional industries with electronic information technology, and then connect and integrate the city's systems and services to improve The efficiency of resource operation, optimize urban management and services, and improve the quality of life of citizens. At the same time, with the rapid development of the next-generation technologies of the Internet of Things, cloud computing, blockchain, and mobile Internet, smart cities are gradually evolving into a new generation of smart cities with trusted sharing, privacy protection, and interconnection capabilities.

AI Technical Summary

Problems solved by technology

However, the traditional silo-structured smart city cannot well realize the mutual access and efficient utilization of data and resources between different departments; if data sharing is realized through centralized and unified management and control, the data security will be greatly reduced, and the data will be vulnerable to Tampering, cannot guarantee trusted access and privacy protection of data between different departments, and even the problem of data tampering may occur
