Taming information-stealing smartphone applications (on Android)

摘要: Smartphones have been becoming ubiquitous and mobile users are increasingly relying on them to store handle personal information. However, recent studies also reveal the disturbing fact that users' information is put at risk by (rogue) smartphone applications. Existing solutions exhibit limitations in their capabilities taming these privacy-violating In this paper, we argue for need of a new privacy mode smartphones. The can empower flexibly control fine-grained manner what kinds will be accessible an application. Also, granted access dynamically adjusted runtime better suit user's needs various scenarios (e.g., different time or location). We developed system called TISSA implements such Android. evaluation with more than dozen information-leaking Android applications demonstrates its effectiveness practicality. Furthermore, our shows introduces negligible performance overhead.
