Abstract

The invention discloses a data sharing method, system and device and a computer readable storage medium, and is applied to a data query party. The method includes: obtaining a target query request for each piece of target data; generating a first random number corresponding to each target query request; based on the first random number and a predetermined target elliptic curve generator, encrypting the corresponding target query request to obtain each encrypted query request; transmitting all encrypted query requests to a data contributor; acquiring an encrypted data set sent by a data contributor; acquiring private key encryption information sent by the data contributor; decrypting the private key encryption information based on the first random number to obtain a target private key of the target data; and decrypting the encrypted data set based on the target private key to obtain target data. According to the method, system and device, the query privacy of the data query party is protected by encrypting the query request; the data privacy of the data contributor is ensured through the encrypted data set and the private key encryption information, and the utilization rate of the data can be improved.

Description

technical field [0001] The present application relates to the technical field of information transmission, and more specifically, to a data sharing method, system, device, and computer-readable storage medium. Background technique [0002] With the advent of the digital economy era, the value of data is getting higher and higher. However, in the process of data application, the data is scattered, and the data owner may not be willing to interact with the data, which makes the problem of "data fragmentation and data island" serious, and the data is difficult to be used effectively. [0003] To sum up, how to improve the utilization rate of data is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of this application is to provide a data sharing method, which can solve the technical problem of how to improve the utilization rate of data to a certain extent. The present application also provides a data sharing system,...
