Abstract

The invention discloses a data security sharing method and device based on a block chain, and a medium. The method comprises, by a data application party, sending a data query request to a data sharing party; according to the received shared data corresponding to the data query request, adopting a hash algorithm to hash the shared data; and matching the obtained hash value with a hash value pre-written into a block chain by the data sharing party so as to carry out security verification on the shared data. The hash value of the shared data is pre-stored in the block chain, so that the data application party can verify the acquired shared data to ensure the security of data sharing.

Description

technical field [0001] The present application relates to the technical field of data security, and in particular to a blockchain-based data security sharing method, equipment, and media. Background technique [0002] With the advent of the information age, data security issues have gradually become the focus of attention. [0003] In the process of data sharing, the data sharing party can share the data it owns, and the data application party can obtain it according to its own needs. [0004] However, the shared data owned by the data sharing party may be in danger of being tampered with, which cannot guarantee the security of data sharing, which will cause the data application party to obtain wrong data, which may further lead to other harmful results. Contents of the invention [0005] The embodiment of the present application provides a blockchain-based data security sharing method, equipment, and media, which are used to solve the following technical problems in the ...
