Smartphones are rapidly becoming the computing and communication platform used by people to perform many activities besides placing and receiving phone calls. However, the protection and security models provided by such platforms do not address many security and privacy concerns of their users. It is aimed at extending the security models and mechanisms of existing smart-phone platforms to support context-aware application with the security and the privacy of their users. Particularly challenging in this domain is to find solutions that can increase the security and the privacy of users and at the same time, they are easy to understand and to use. MOSES can also be improved in several aspects. For instance, to make the policy specification process easier, a solution could be to embed into the system policy templates that can be simply selected and associated to an application. It should be mentioned that currently MOSES does not separate system data (e.g., system configuration files) and information on SD cards. In the future it is planned to add this functionality to the system. Moreover, performance overheads are also planned to be reduced considerably in the future versions.
