Mandatory access control for Android application

For security of Android operating systems, permission-based solutions are one of popular approaches but still exposed to two problems. First, there is coarse-grained relationship between a permission and its associated methods. Second, mobile users do not have rights to control the permissions of their applications. To solve these problems, we propose MacDroid that enables users to control the system resources of the installed applications through its policy. MacDroid classifies the permission into method units. The results of our performance test show that MacDroid is able to enforce its policy without too much overhead compared to the pure Android systems.
