Abstract:
|
Smartphones have been largely used in recent years, due to their capabilities of supporting many applications, from simple alarm clocks to complicated Internet services. Most of them store users' private information. However, the security model for smartphone end users is still a two-state model in which they can do anything or absolutely nothing, and it is no longer suitable. In this paper, we propose (DiffUser), a differentiated user access control model to enhance smartphone security and user privacy. We analyze the demands of different types of users and present a corresponding access control model. We implement our prototype on T-Mobile G1 smartphones and the evaluation results show that our system is lightweight and flexible.
