Information flow in mobile phones

Mobile phones are entrusted with a great deal of private information, including both explicitly-supplied documents (e.g., contacts, email and documents), and autonomously-acquired sensor data (e.g., location and audio/video recordings).

 

In current mobile platforms, externally-supplied applications can access much of this data, risking grave privacy violations; and research has indeed found numerous such cases, showing that current protection mechanisms are inadequate.

 

We are developing improvements to the Android platform, which more tightly control information flow and let users more effectively reason and decide what private information may be exposed and to what end.
