%X The privacy mode in Android has some defects and is lack of effective mechanisms to prevent loss of privacy between applications. This paper proposed a new privacy protection model by using the fine-grained permissions and privacy data tainting. Firstly the method could prevent loss of privacy from a single application by dynamically configuring the permissions in a fine-grained manner. By leveraging the track of the tainted privacy data it could prohibit the propagation of the privacy data between applications which had different permissions on the accordingly privacy tag. Repeatly experimental tests show the model is able to effectively protect the privacy of data within the Android application, and to detect the privilege escalation attacks between applications so as to isolate the private data. As a result, the full range of private data within Android is in protection, and leads a new direction for related research in the future.
