Abstract: With the popularity of smart mobile phone, the harm of intrusion is more and more serious. This paper is, based on the Android smartphone platform, combined with intrusion detection research, to solve the problem of intrusion detection of smartphone. In order to give a reasonable judgment and update the phone as soon as possible, the paper collects the system and the network characteristic data on the Android platform, and uploads them to the remote cloud servers, then analyzes using Support Vector Machine（SVM）. The experimental results show that, taking the kind of mechanism not only can reduce resource consumption of smart phones, but also can handle and response the intrusion as quickly as possible.
