Supporting Mobile Privacy and Security through Sensor-Based Context Detection

This position paper addresses challenges of data privacy and security support for mobile phones. We describe the system TreasurePhone [5] which implements a context-sensitive security model. Data privacy and security is realized by spheres, which represent the user’s context specic need for privacy. That is, users can create spheres and dene which services and data are accessible in each sphere. TreasurePhone integrates context information for supporting authentication and activation of spheres by locations and actions. Finally, we propose dierent approaches for advancing the concepts of TreasurePhone and context based privacy protection on mobile devices.
