Problems solved by technology

However, there are still deficiencies in this method, and it cannot guarantee the security of users accessing sensitive data on mobile terminals.
User mobility leads to frequent and unpredictable changes in user location and available resources
In this way, even for users with higher authority, there is also a risk of confidential information leakage when using mobile terminal equipment in an unsafe situation

Abstract

The invention discloses an access control system and method based on context awareness for a mobile platform. A plurality of technologies such as position locating, context awareness and data mining are utilized comprehensively. Specific to the problem of information protection during data operation of a mobile terminal, the advantages and disadvantages of an existing access control technology are analyzed, a scheme for deciding a security access strategy based on a user context is proposed, and an access control technology based on the context awareness for the mobile platform is designed and implemented. An environment in which a user is located is judged accurately through a position locating technology and an audio-based context identification technology, and a current environment safety risk level is judged optimally with a pedestrian crowding degree judgment algorithm. User access is influenced and classified information is operated, so that the classified information is prevented from being intercepted and peeked on the mobile platform.

Description

technical field [0001] The invention belongs to the technical field of public security identification, and relates to an access control system and method, in particular to an access control system and method based on context awareness on a mobile platform. Background technique [0002] Context Awareness technology originated from the research of so-called ubiquitous computing, which was first proposed by Schilit in 1994. Situational awareness has many definitions. Simply put, it is to enable computer equipment to "perceive" the current situation through sensors and related technologies. There is also a lot of information that can be used for situational awareness, such as temperature, location, acceleration, audio, video, and so on. [0003] Access Control (AccessControl) refers to the means by which the system restricts the user's identity and the predefined policy group to which it belongs to use data resources. It is usually used by system administrators to control user...
