Method and system for secure sharing of data between first region and second region

Abstract

The embodiment of the invention provides a method and system for secure sharing of data between a first region and a second region. The second region is provided with a security use platform; and the first region encrypts plaintext data to be shared to a plurality of users of the security use platform to generate an encrypted data file. The method comprises the steps of generating a key file according to a target access permission of a target user in the plurality of users to the encrypted data file, wherein the encrypted data file needs to be accessed by using a key file through the security use platform; generating an evidence storage file according to a security management and control strategy configured for the encrypted data file, wherein the security management and control strategy comprises respective access permissions of a plurality of users; transmitting the encrypted data file and the key file to a target user through a gatekeeper; and transmitting the evidence storage file to the security use platform through the gatekeeper, and controlling the target user to use the data in the encrypted data file by the security use platform according to the security management and control strategy in the evidence storage file. Data sharing and data security can be both considered.

Description

technical field [0001] One or more embodiments of this specification relate to the computer field, and in particular, to a method and system for securely sharing data between a first area and a second area. Background technique [0002] While the country is vigorously promoting data openness and sharing, there has always been a core difficulty in data sharing: data security. [0003] In the current data sharing scenario, once the data is transferred from the data owner to the data user, the actual control of the data belongs to the data user, and the data user can retain the data and use it in unauthorized scenarios, Even if it is resold, the data owner has no control over all usage of the data. [0004] Therefore, it is hoped that there will be an improved solution that can improve the data owner's ability to control the shared data, so as to take into account both data sharing and data security. Contents of the invention [0005] One or more embodiments of this specifi...
