SmarPer: Context-Aware and Automatic Runtime-Permissions for Mobile Devices

Smart Permissions (SmarPer) is an advanced-permission mechanism for Android, with support for finer-grained permissions, context-awareness and multiple decision-levels. In addition, to help users manage permissions more efficiently and reduce permission fatigue, SmarPer provides (semi-) automatic decisions. In doing so, we will provide users with smarter controls for protecting their private information, with a lower overhead for users. We provide the source code for the SmarPer prototype in Android and the Machine Learning framework used in the SmarPer project.

This project is organized as follows:

• SmarPerApp/: SmarPer prototype in Android, based on XPrivacy.
• ML/: Machine Learning framework for carefully training and comparing different context-aware models that predict permission decisions.

For more details about the SmarPer project, refer to the research paper and the SmarPer website.
