Physical environment perception based computer access control method and system

Abstract

The invention relates to a computer access control method and a system based on the condition of the physical operating environment. The computer access control method comprises following steps: perceiving state information of the physical environments of controlled computer systems in a real-time mode and pushing state information of physical environments to an information access control system, equipping a management control center system with different access control policies and sending policies down to different information access monitoring systems of the different controlled computers, determining information contents being accessed in accordance with the access policies by the information access monitoring systems when the physical environments change and preventing the computers from processing information if information contents are not suitably accessed by states of physical environments after the changes. The constructed system is capable of managing and controlling accesses of electronic files of the computers according to environmental states, breaks the protection limitations of file access control over domains, authorities and the like in a current document management and control system, steps up management and control efforts of information contents of the computers and further reduces possibility of sensitive information leakage.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a computer access control method and system based on physical environment perception. Background technique [0002] With the widespread use of mobile computing, people can conduct electronic office anytime and anywhere. While mobile office improves people's efficiency, it also makes it easier for information to be exposed in unsafe spaces. Although most information leaks occur in cyberspace, it is not uncommon for information to be stolen by "eyes across the table" in physical space. If this kind of information leakage occurs in the leakage of personal privacy information, it will not cause great losses. If it is related to commercial secrets or state secrets, the loss is difficult to estimate, and it is difficult to trace the source of such leakage. [0003] This patent proposes a computer information access control method based on physical environment perception, wh...
