A user data management method and device based on a block chain

Abstract

The embodiment of the invention provides a user data management method and device based on a block chain. The method comprises the steps that a block chain data management system used for user data management is established; Wherein the block chain data management system comprises a user terminal equipment node and a network service provider node; And the user terminal equipment node and each network service provider node realize authority management and security management of the user data through the block chain data management system. According to the embodiment of the invention, authoritymanagement and security management of the user data are realized in a block chain manner.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, and in particular to a block chain-based user data management method and device. Background technique [0002] With the popularization of the Internet, massive amounts of data are produced and created by Internet users, and these data are increasingly valued and utilized. The concept of data assets is gradually accepted by all walks of life, but data producers lack management of the data and personal information they create. that power. The issue of personal privacy protection and data ownership and disposal rights has been paid more and more attention.

Problems solved by technology

[0004] 1) The collection of data is scattered, and each organization can only obtain data through the Internet services provided by itself, and cannot form the circulation of data;

[0005] 2) The security of data information is poor. The data generated by the target user’s terminal equipment accessing the Internet and using various application software is abused and embezzled. There is a lack of effective supervision and management methods. Due to the leakage of personal privacy, a large amount of harassment information and even property losses are caused;

[0006] 3) Data ownership is not clear, data creators (users) have no right to the data they create, and most of the revenue generated by data is owned by the company that owns the data
