Abstract

The invention relates to a data acquisition method and device based on blockchain, computer equipment and a storage medium. The method comprises the steps: obtaining a data model generated by a demandside, and determining a first permission category corresponding to source data to be accessed by the demand side according to the data model; extracting authorization information from a data authorization block on the blockchain, wherein the authorization information comprises demander information, provider information and a second authority category corresponding to source data accessed by the demander authorized by the provider; if the first permission category is included in the range of the second permission category, importing the authorization information into the data model to obtain source data to be accessed by the demander according to the authorization information, and generating a target data set based on the obtained source data through the data model; and sending the targetdata set to the demand side. By adopting the method, the security in the data acquisition process can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a blockchain-based data management method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology and the rapid development of big data technology, data fusion and sharing are the basis of big data technology, and ensuring data security in the process of data fusion and sharing is an urgent problem to be solved. [0003] At this stage, when data is obtained in the process of data fusion and sharing, it is easy to cause data theft or leakage, and the data security is low. Contents of the invention [0004] Based on this, it is necessary to provide a blockchain-based data acquisition method, device, computer equipment, and storage medium that can improve data security for the above technical problems. [0005] A block chain-based data acquisition method, the method comprising: [0006] Obtaining the d...
