Abstract—The openness of Android OS and the easy development of applications have attracted a large number of enthusiasts to join in. Due to the deficiencies of permission mechanism of Android OS, an Android privacy protection system called Protectedroid is presented in this paper which is a model based on grey list and enables the design of security strategies more easily. Protectedroid adds an enforcing privacy protection module between App and private data. When an application is added to the grey list and intends to access sensitive data and resources, Protectedroid will intercept data access request and return false objects for the grey applications. Experimental results show that: Protectedroid can effectively throttle the privacy leakage and ensure the effectiveness and stability of the entire system.
