CONTEXT-BASED ACCESS CONTROL SYSTEMS FOR MOBILE
DEVICES
ABSTRACT:
Mobile Android applications often have access to
sensitive data and resources on the user device. Misuse of this data by
malicious applications may result in privacy breaches and sensitive data
leakage. An example would be a malicious application surreptitiously recording
a confidential business conversation. The problem arises from the fact that
Android users do not have control over the application capabilities once the
applications have been granted the requested privileges upon installation. In
many cases, however, whether an application may get a privilege depends on the
specific user context and thus we need a context-based access control mechanism
by which privileges can be dynamically granted or revoked to applications based
on the specific context of the user. In this paper we propose such an access
control mechanism. Our implementation of context differentiates between closely
located sub-areas within the same location. We have modified the Android
operating system so that context-based access control restrictions can be
specified and enforced. We have performed several experiments to assess the
efficiency of our access control mechanism and the accuracy of context
detection.
