RecDroid: a resource access permission control portal and recommendation service for smartphone users

The rapid growth of smartphone application market raises security concerns regarding untrusted applications. Studies have shown that most apps in markets request to collect data irrelevant to the main functions of the apps. Traditional permission control design based on one-time decisions on installation has been proven to be not effective to protect user privacy and poorly utilize scarce mobile resources (e.g. battery). In this work, we propose RecDroid, a framework for smartphone users to make permission control in real time and receive recommendations from expert users who use the same apps. This way users can benefit from the expert opinions and make correct permission granting decisions. We describe our vision on realizing our solution on Android and show that our solution is feasible, easy to use, and effective.
