Data sharing method and device based on block chain, computer equipment and storage medium

Abstract

The invention relates to a data sharing method and device based on a block chain, computer equipment and a storage medium. The method comprises the following steps of obtaining a data sharing requestfrom a sharing node; judging whether the sharing node sending the data sharing request belongs to the sharing node of the alliance chain or not; if so, obtaining corresponding shared data and uploading the corresponding shared data to the shared node; and recording the shared data to an alliance chain, and broadcasting the shared data to all shared nodes in the alliance chain for storage. According to the data sharing method based on the block chain, sharing nodes of organizations in an alliance organization are mutually constrained and supervised while sharing data, so that the information island phenomenon is solved; the management complexity is effectively reduced through the autonomy of each shared node; the distributed and multi-redundancy characteristics ensure that the blockchain has no single-point failure fault, and even if part of the shared nodes fail, the shared data in other shared nodes is not affected, and the method is more reliable than a centralized system.

Description

technical field [0001] The present invention relates to the field of data sharing, and more specifically refers to a blockchain-based data sharing method, device, computer equipment and storage medium. Background technique [0002] With the infiltration of Internet big data into all walks of life and the increasing data scale and value, the potential value mined through data sharing has become more and more important; Aiming at a series of issues such as how to ensure that data owners let go of suspicion and trust, effective It is the basic consensus and demand for open and shared data to solve the problem of "data islands" and to protect users' sensitive information and confidential data from being illegally obtained and used while opening and sharing data. [0003] The current data sharing methods mainly include traditional data sharing schemes and centralized data sharing schemes; traditional data sharing schemes use traditional privacy protection methods to achieve inter...

AI Technical Summary

Problems solved by technology

[0005] Existing traditional sharing schemes reduce privacy risks by refusing to open to the outside world, not only cannot tap the potential value of data, cannot maximize its benefits, but also cause information construction to lag behind; although the centralized data sharing scheme solves the problem of mutual distrust, However, due to the security issues brought about by the concentration of data in a third party, the third party cannot guarantee absolute data security, and once a data leak occurs, it will cause serious consequences
