Problems solved by technology

[0003] However, although there is a data sharing platform similar to NCBI (National Center for Biotechnology Information), in the process of sharing and using data, data will inevitably be exposed, and data security cannot be guaranteed
Although federated learning, zero-knowledge proof and other technologies provide the possibility of data "available but not visible", in the process of data analysis and use, data users and data contributors need to communicate frequently, which affects the efficiency of data analysis

Abstract

The invention provides a data sharing method and device. The data sharing method comprises the following steps: acquiring encrypted data to be analyzed in a data sharing platform selected by a data user; decrypting the to-be-analyzed encrypted data through a trusted execution program, conducting data analysis on the decrypted data, and obtaining a data analysis result of the to-be-analyzed encrypted data, and building identity authentication information of a data user in the trusted execution program, wherein the execution process of the trusted execution program is invisible to the data user. The security of shared data in the data sharing process can be ensured, and the data analysis efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of data sharing, in particular to a data sharing method and device. Background technique [0002] Data sharing can reasonably achieve resource allocation, save social costs, and create more wealth. It is an important means to improve the utilization of data resources and avoid repeated waste in data collection, storage, and management. [0003] However, although there is a data sharing platform similar to NCBI (National Center for Biotechnology Information), in the process of sharing and using data, the data will inevitably be exposed, and the security of the data cannot be guaranteed. Although technologies such as federated learning and zero-knowledge proof provide the possibility of "available but invisible" data, in the process of data analysis and use, data users and data contributors need to communicate frequently, which affects the efficiency of data analysis.
