Repackaged apps detection based on similarity evaluation
2016
With the rapid development of the apps on mobile phones, it brings some hidden troubles to us. The app lack of security protection mechanism might be tampered and repackaged into a new app, and this new app can be released into application markets. Based on the call hierarchy of the classes in an android package, we develop a similarity evaluation method of apps. This method sets a similarity threshold, and if the similarity value of two apps is higher than the threshold, one app of these two is thought to be repackaged and derives from the other. By applying this method to an experiment, it is proved that this evaluation system is of high accuracy and expansibility.
