Abstract

The embodiments of this specification provide a personal information protection data sharing method, device and electronic equipment. Among them, the method includes: the first service provider sends a data query request to at least one second service provider based on the inadvertent transfer protocol, wherein the data query request is used to obtain the service data of the target user, and does not carry a data query request for characterizing The parameters of the target user. The first service provider receives the data query result returned by the at least one second service provider, wherein the data query result returned by each second service provider carries information of multiple users including the target user. Service data, each service data is encrypted based on the encryption parameters of the user to which the service data belongs. The first service provider decrypts the returned data query result based on the encryption parameter of the target user to obtain the service data of the target user.

Description

technical field [0001] This document relates to the field of data processing technology, in particular to a data sharing method, device and electronic equipment for personal information protection. Background technique [0002] In the application of big data analysis, more complete information mining can be realized through data sharing between institutions, thereby improving service quality. However, in many fields, regardless of the data itself, querying data is also highly sensitive because it will reveal the intent. In addition, there is a common competitive relationship among institutions, which makes data sharing difficult to achieve. This damages the institutions themselves. Benefit. [0003] In view of this, how to protect the privacy of the personal information of the data acquirer in a trusted data sharing environment is a technical problem that needs to be solved urgently. Contents of the invention [0004] The purpose of the embodiment of this specification i...
