Constroid takes arst step to over come the capability
and process-centric security model of Android. It addresses
the elemental requirements of users who must guard the privacy of data but also need to process it with applications
running in various contexts. whether
an application should be able to perform actions on
resources we invert this approach and which actions
should be allowed for data items. In so doing, we will
able to counteract applications or groups of applications
which process data in ways not granted by the user.
