A permission detection system which is combined with PC
and mobile phone side is proposed. The system can detect
permission information of installed APPs and the uninstalled
APK file in advance. The system architecture shown in figure
3 consists of two modules: permissions on the basis of
decompilation module and permissions on the basis of the
PackageManager module, among which, the second one can
be deeply divided into two parts: extracting the corresponding
permissions for each APP according to the list of APPs, and
listing the permissions; monitoring all the APPs that using a
specific sensitive permission according to a number of
sensitive permissions, and listing APPs. By combining the
two monitoring functions, the system can help users
understand the permissions deeply and constantly monitor the
APP permission information so that it can help guarantee the
safety of the system, and protect users' privacy information
security.
