A data sharing exchange system and method based on a block chain

Abstract

The invention discloses a data sharing exchange system and method based on a block chain. The system comprises a data sharing exchange center, a front-end system and a block chain basic platform. Thedata sharing exchange center comprises a data sharing exchange control system, a data resource center and a client; The front-end system comprises a data acquisition system, a shared exchange module and a feedback module; The block chain basic platform comprises an alliance chain module and a data sharing exchange management module, the alliance chain module is responsible for intelligent contractand verifying credibility configuration of nodes, the intelligent contract generated in the data sharing exchange process is verified, and the data sharing exchange center communicates with the front-end systems in an alliance chain mode. According to the invention, the credit problem and the incentive problem of data sharing exchange in a multi-party participation environment are solved, the security and the reliability are ensured, the enthusiasm of a user for publishing and updating the sharing exchange data is promoted, and meanwhile, the guiding effect on user decision can be realized.

Description

technical field [0001] The invention relates to the field of data sharing and exchange, in particular to a blockchain-based data sharing and exchange system and method. Background technique [0002] In recent years, the national informatization construction has been continuously improved and developed. Many units and departments have established their own business application systems. The key cross-departmental business systems have been designed as independent systems within the department. The joint construction and sharing of information resources cannot Reached a consensus that the potential "information island" risk is prominent, and business collaboration capabilities are greatly constrained. There are many reasons for information islands, which can be summarized into three aspects: first, users have independent and heterogeneous information management systems, which are difficult to communicate with each other; second, data coding standards and interface specification...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the defects in the current informatization construction process that each unit is self-contained, the awareness of active data sharing is weak, the leading unit cannot grasp the information sharing situation as a whole to make corresponding decisions, and the security of the data sharing and exchange process is not guaranteed, etc., to establish a Based on the blockchain-based data sharing and exchange mechanism, through the statistical measurement of the data sharing of each unit, the quantification of data quality is achieved, the value of data is clarified and the security of data exchange is guaranteed, and the awareness of sharing is encouraged to achieve mutual benefit and win-win results
