Android forensics has evolved over time offering significant opportunities and exciting challenges. On one hand, being an open source platform Android is giving developers the freedom to contribute to the rapid growth of the Android market whereas on the other hand Android users may not be aware of the security and privacy implications of installing these applications on their phones. Users may assume that a password-locked device protects their personal information, but applications may retain private information on devices, in ways that users might not anticipate.

Opacity Of Discrete Event Systems: Analysis And Control, Majed Mohamed Ben Kalefa
Wayne State University Dissertations
The exchange of sensitive information in many systems over a network can be manipulated
by unauthorized access. Opacity is a property to investigate security and
privacy problems in such systems. Opacity characterizes whether a secret information
of a system can be inferred by an unauthorized user. One approach to verify security
and privacy properties using opacity problem is to model the system that may leak confidential
information as a discrete event system. The problem that has not investigated
intensively is the enforcement of opacity properties by supervisory control. In other
words, constructing a minimally restrictive supervisor to limit the system's …
