Improving Mobile Application Security via Bridging User Expectations and Application Behaviors

To keep malware out of mobile application markets, existing techniques analyze the security aspects of application behaviors and summarize patterns of these security aspects to determine what applications do.

This poster presents our recent work on bridging the semantic gap between user perceptions of the application behaviors and the actual application behaviors.
