myTunes: Semantically Linked and User-Centric Fine-Grained Privacy Control on Android
Smartphone operating systems provide designated databases and services for user's private information (e.g., contacts data and SMS or location) that can be conveniently accessed by 3rd party apps through clearly defined APIs. The popular android OS deploys a permission framework and a reference monitor to protect the interfaces of these security and privacy sensitive components. However, android's default permissions are too coarse-grained and inflexible to provide sufficient protection of users' privacy as recent privacy violation incidents show. Recently several privacy-protection solutions on android have been proposed.
