Abstract

The invention provides a data sharing method and a data sharing system capable of protecting user data ownership, wherein the method comprises the following steps: establishing a data sharing alliance; in response to a data query operation of a first alliance member, in the form of a list, returning back data dimension meeting requirements in a blockchain copy and information of a second alliancemember, namely an owner of the data, to a user; based on authorization information of the user to the data dimension which can be queried by the first alliance member, controlling the second alliancemember to verify the authorization information of the user; after the authorization information passes the verification, controlling the second alliance member to apply to an own central database forquerying metadata of the user, and returning back the user authorization data queried from the central database to the first alliance member in the form of digital encryption. According to the methodand the system provided by the invention, a problem of trust among the alliance members is eliminated through the blockchain, and consequently, a data barrier problem is solved effectively. On the basis of protecting the user data ownership, data sharing among the alliance members is realized.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a data sharing method and system for protecting user data ownership. Background technique [0002] With the increase in the volume of data, experts and scholars at home and abroad are aware of the importance of data, and the concept of data as assets has gradually been recognized. In the future, data will bring value to enterprises as an intangible asset. But the prerequisite for data to generate value is that it can be processed and utilized, rather than simply stored in a database. At this stage, due to commercial interests and privacy protection considerations, enterprises or departments are not willing to share data in order to give full play to the value of data. From the user's point of view, the related data that users browse, consume, and establish on the service platform do not belong to a certain company. These data should belong to the user. Companies hav...
