Data security tracing method and device based on block chain

Abstract

The invention discloses a data security tracing method and device based on a block chain, and the method comprises the steps: collecting operation log data for executing a preset operation on target data,wherein the preset operation comprises at least one of the following operations: adding, deleting, modifying and checking; storing the operation log data to an operation log chain of each node ofthe blockchain network, the operation log chain storing hash values corresponding to the operation log data; superposing the hash value corresponding to the operation log data to an information display page for displaying the target data; and based on the hash value extracted from the information display page, querying operation log data which is stored on the blockchain network and performs a preset operation on the target data. According to the invention, the data security of the data on the data platform in the storage, use and sharing processes can be ensured.

Description

technical field [0001] The present invention relates to the field of data security, in particular to a blockchain-based data security traceability method and device. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the rapid development of information technology, people pay more and more attention to data security. Especially with the emergence of big data technology, various big data processing platforms have emerged as the times require, and the amount of data has grown rapidly. How to ensure that these data are not leaked or tampered in the process of storage, use, and sharing is an urgent problem to be solved in the era of big data. [0004] At present, the existing data platform configures different permissions for different operators to achieve limited access or o...
