Context-aware Authorization Model for Smartphones

Smartphones are considered as the most pervasive electronic devices all over the world. These handheld devices are carried with people wherever they go. Thanks to the availability of communication infrastructures anywhere, people depend on these devices to accomplish some tasks related to their work (resp. study), indispensable social media tool and a storage tool for a lot of user's private content such as photos, videos, messages, emails, etc. For that, smartphones should be protected against unauthorized access. Current access control models to services and applications of the smartphones are static (fixed) even though the user context is dynamic, and some access control model could not be appropriate in some contexts for the security and safety of both user's privacy and smartphone. Moreover, existing access control models are not dedicated to personal devices like smartphones but oriented to multi-users and network devices. In this paper I propose a context-aware access control model for smartphones which adapts dynamically to the user's context and provide appropriate access control mechanism to improve the security and safety of both user's privacy and smart phones.
