Start target APP.In this way, a mobile APP of encryption can be installed and run under the system.
3. the control of authority (permission control) of context aware (context-aware)
Android is static for the control of authority of mobile APP.Under Android system, the developer of an APP needs statement
The authority of system resource is used needed for the APP of its exploitation.After this APP is installed, Android user may decide that authorize or
Person revokes certain authority of this APP.The control of authority of context aware can further improve the security of the running environment of APP.Reason
By as follows：1) control of authority of context aware is dynamic, its authority for adjusting APP come dynamic by context aware；2) scene
The control of authority of perception can automatic management, its authority that dynamic adjustment APP in ground is automated by default safety regulation；3)
Many malice APP are ceased by the authority that user authorizes to attack the mobile system of user or steal user's private ownership, scene sense
The control of authority known can effectively prevent the attack of such Malware.
Fig. 5 describes the schematic diagram of the control of authority that context aware is realized in the system and invention.The system and invention
Isolated with the machine mobile system by moving APP and operating in security procedure target.By a series of hooks, the system will
Target moves access captures of the APP to system resource.As shown in figure 5, the system is by realizing that it is right to carry out that system service is acted on behalf of
The scene of target movement APP is perceived, and dynamic control of authority is made to it.Target moves visits of the APP to system resource
Ask system service agency's capture that request will be realized by the system.The system service broker will inquire about dynamic user-privilege management rule,
And judged with reference to scene instantly.If agreeing to access of the target APP this time to system resource, the system service broker will visit
The system service under true mobile environment is asked, obtains system resource or information, and these resources or information are returned into target to enter
Journey.Target APP this visits are such as vetoed, the system service broker can directly refuse request, return to null value or according to rights management
The dummy values (dummy value) of rule setting.
4th, System Working Principle/technical background embodiment
