Embodiment Construction

[0045] In practical applications, for each organization, the data of each user kept by the organization belongs to the private data of the organization. Since an effective trust mechanism cannot be established among various organizations in the prior art, these Private data is generally not shared with other organizations.

[0046] Because in the prior art, each institution does not share the data of each user in its own custody with other institutions, therefore, each institution cannot effectively provide users with better services based on more comprehensive data.

[0047] To this end, in this specification, each organization can build a consensus network, and each organization can store and query data through the corresponding blockchain nodes in the consensus network. Specifically, each organization can correspond to each blockchain node, and each organization can store the data of each user in its own custody in the blockchain through its own corresponding blockchain nod...

Abstract

The invention discloses methods, devices, and apparatuses for data inquiry and data sharing. In the method, a block chain node can determine a user identification corresponding to to-be-queried data,and according to the user identification, a data inquiry request is generated, and the data inquiry request is broadcasted to each of other block chain nodes. Aimed at each of other block chain nodes,when authorization information returned by the other block chain node aimed at the data inquiry request is received, data of a user corresponding to the other block chain node in the block chain stored by the block chain node can be decrypted according to the authorization information, to query data of the users corresponding to the other block chain nodes in the block chain.

Description

technical field [0001] This specification relates to the field of computer technology, in particular to a method, device and equipment for data query and data sharing. Background technique [0002] At present, each organization will count and save the data of each user, so as to provide services for each user through the saved data of each user. [0003] However, since there is usually no effective trust mechanism established among various institutions, each institution will not share the data of users in its own custody with other institutions. At the same time, it is impossible to carry out risk prevention and control based on more comprehensive data. [0004] For example, institutions usually do not share their own risk records, fraud lists and other risk data with other institutions. In this way, institutions will not be able to query more comprehensive risk data to carry out risk prevention and control based on comprehensive risk data, which may lead to some malicious...
