Due to the advantages of open source and portability, Android has become a mobile OS with the largest market share. Various attacks toward Android also emerge in endlessly, the Android-oriented detection for malwares has become a quite important link recently in the field of mobile safety. The problems to be faced include difficult collection of malicious software, imbalanced proportion of the abnormal samples and normal samples. In order to effectively overcome the above difficulties, Droid-Saf framework was proposed, a data processing scheme revealing the implicit characteristics of data was proposed in the framework; the hidden information contained in the sample was treated as a new feature; in modeling, the sample features were integrated into the algorithm and dynamic slack variables were established. Static analytic method was applied to decompile apk, the improved svdd single classifier was used for classification, the deficiency of difficult collection of abnormal software in the system for detecting malicious software was overcome, the rate of missing report and the misjudgment rate of abnormal detection were lowered. The Experimental results verified the effectiveness and applicability of the algorithm.
