Data processing method, device, equipment and storage medium based on consortium chain

Abstract

The embodiment of the present application provides a consortium chain-based data processing method, device, device, and storage medium. The method includes: after the first data node receives the data request message sent by the second data node, send The first blockchain node queries the authorization information of the authorized user; if the authorization information of the authorized user includes the identification of the second data node and the identification of the requested data, the first data node sends the requested data to the second data node. It can be seen that in this application, the data node of the data provider can accurately verify whether the authorized user has authorized the requested data to the data node of the data applicant through the authorization information of the authorized user queried by the blockchain node based on the alliance chain. , so that not only the security of the user data of the authorized user can be guaranteed, but also the sharing of the authorization information of the authorized user can be realized, which is further conducive to improving the efficiency of obtaining the requested data.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a consortium chain-based data processing method, device, device, and storage medium. Background technique [0002] With the development of computer network technology, data sharing between associated customers is becoming more and more common. [0003] In the prior art, the data user sends an application message for requesting user data to the data provider offline or online (carrying proof materials indicating that the user has been authorized); further, the data provider After receiving the application message, the certification materials will be reviewed, and the user data will be provided to the data provider after the review is passed. [0004] In the existing method, since the certification materials are signed by both the data user and the user, it is difficult for the data provider to verify the authenticity and / or validity of the certification materials,...
