Abstract:

In the era of intelligent mobile terminal, because of the characteristics of openness and free of charge, Android has become one of the major operation systems on the market. However, a large number of Android viruses, Trojans and malicious software have been serious threats to the privacy and property securities of smart phone users. In the Android operation system, although it is necessary to apply the authorities to the system for sensitive operations, and there are some system modules related to authority control, malicious software can use the system vulnerabilities or third party program vulnerabilities to carry out the attack. To meet the need of Android applications sensitive behaviors detection, this paper analyzes the popular applications behaviors detection tools in the Android system, designs and implements an Android applications dynamic detection system. The system can monitor the Android applications sensitive behaviors in real time, and provides help for the detection of malicious programs.

Key words: Android application, sensitive behavior, dynamic monitor
