Abstract: As the mobile phone plays a more important role in our life, the problem about security and privacy of smart phone become more prominent. To solve this problem, this paper presents an approach to implement more virtual phone (VP), which is based on Linux container technology, running two or more Android systems in a single smart phone device. In order to allow each VP uses devices concurrently, we present a virtualization technology based on device proxy, and realize it on radio device. A prototype system is implemented on Nubia Z7max smartphone and the functionality of virtualization, data isolation etc. are tested. The experiment results show that our approach is useful and feasible. Each VP can simultaneously shares devices, user's data about devices and applications are isolated between isolated Android systems, and the system cost is kept in allowable range. Due to the VPs are isolated each other, there are three benefits:this approach can protect the user's privacy effectively, even one VP is corrupted the whole system can still work, and it also can satisfy user's personalized demand because the VP's functions can be customized by application scenarios and user's requirements.
