Anti-obfuscation Android application similarity detection method based on API call

Abstract

The traditional Android application similarity detection methods have the problem of complex feature extraction and low detecting efficiency. Regarding the issue above, an anti-obfuscation Android application similarity detection method based on API call was proposed. Firstly, it extracts referenced API sequence from the dex file. Counting the number of referenced API after decompiling the application to build feature vector. Finally, calculate the application similarity through feature vector. The experimental results show that the method has high accuracy.
