Abstract

The invention is suitable for the technical field of block chains, and provides a data sharing method and device, a terminal and a storage medium. The method comprises the steps: initiating, by an initiator node, encrypted information sharing with N groups of participant nodes related to a data sharing task based on the data sharing task; and receiving encrypted shared data sent by the first group of participant nodes in the N groups of participant nodes, and decrypting the encrypted shared data based on the encryption information to obtain shared data. According to the scheme, the operation efficiency can be improved on the premise of ensuring the algorithm security.

Description

technical field [0001] The present application belongs to the technical field of blockchain, and in particular relates to a data sharing method, device, terminal and storage medium. Background technique [0002] Data is a very important national resource, but due to security, compliance and some historical reasons, data is backlogged in various enterprises, forming a data island. How to make data flow safely is a problem that needs to be studied at this stage . [0003] In the existing technology, federated computing, especially the privacy union in federated computing, is a solution to this problem, which can realize the flow of value without data out of the database. [0004] For example, if there is an organization A that needs the data union of organization B, organization C and organization D, organization A can obtain the union of all data sets after using privacy union, but it is impossible to know the specific source of each element in the collection Which institut...
