Access and output reviewing method and device for preventing data divulgence, and reviewing system

Abstract

The invention discloses an access and output reviewing method and an access and output reviewing device for preventing data divulgence, and a reviewing system. The reviewing system comprises a data area, a data request party, an access reviewing device, and / or an output reviewing device. The access reviewing device comprises a receiving module which is used for receiving an access request for the data in a memory from the data request party, a reviewing module which is used for reviewing the access request based on a reviewing strategy, and a processing module which is used for allowing or refusing the access request according to a reviewing result of the reviewing processing. The output receiving device comprises a receiving module which is used for receiving an output request for the data in the data area from the data request party, a reviewing module which is used for reviewing the output request based on the reviewing strategy, and a processing module which is used for allowing or refusing the output request according to a reviewing result of the reviewing processing.

Description

technical field [0001] The invention relates to an access and output review method and device for preventing data leakage, and a review system. Background technique [0002] In the prior art, due to the storage capability and computing capability of the cloud platform, the big data cooperation system based on the cloud platform is widely used. The data provider can use the cloud platform to store big data and process the original big data to generate data that meets the requirements of the data requester. However, in the data cooperation and transaction process involving multiple parties, there are big problems in data security. [0003] Traditional data leakage prevention methods usually encrypt data. However, although encrypted data ensures data security, the calculation method for data is limited. Patent document CN101572699A proposes a method for controlling files to be sent out through the network. However, this method only prevents sensitive data from leaking out by ...

However, in the data cooperation and transaction process involving multiple parties, there are big problems in data security

[0003] Traditional data leakage prevention methods usually encrypt data. However, although encrypted data ensures data security, the calculation method for data is limited.

Patent document CN101572699A proposes a method for controlling files to be sent out through the network. However, this method only prevents sensitive data from leaking out by counting the data sensitivity and data control strictness of network packets. In the big data environment of the cloud platform, The data generated in the data transaction process is dynamically generated and changes at any time, so it is difficult to define its sensitivity and control strictness

Patent document CN101950296A proposes a method and system for cloud data auditing. Although it proposes to monitor, audit and mark data content, and restrict the use of data, the system and method do not perform any data access and output. censorship and restrictions, and cannot ensure data security
