With the increase of mobile payment malicious applications, an accurate assessment of their safety is particularly important.In recent years, machine learning methods have achieved good results in text recognition, medical diagnosis, anomaly detection and other fields.Therefore, we consider the introduction of the application of many features including application signature information, application permissions, suspicious API, special string to construct a sample feature space and evaluate the safety of mobile payment applications based on support vector machine algorithm.By comparing the accuracy of a variety of algorithms, the algorithm is turned to be feasible.The importance of the evaluation index is different during the sample classification and there is a difference in the performance of the kernel function under different conditions.So this paper studies the performance of the classifier in different evaluation index set, kernel function and feature weights.It proves that the polynomial kernel support vector machine method is best based on feature weights after the introduction of four types of evaluation index.This method properly avoids the problem of low accuracy due to a single feature while eliminating the adverse effects of weak correlation evaluation index.
