A New Secure Android Model Based on Privilege

Android is the most popular smartphone operating system in the world. There are many people who focus on Android security and dedicated to improve android security. There are many android vulnerabilities exposed online and attackers can use these vulnerabilities to steal our private and sensitive information and attack our device. In the paper, we propose a novel secure android model based on privilege. We create three kinds of users and grant different users different permissions. Thus, users can have more freedom and control over their android device in the model we proposed. In our secure model, users can upgrade their android operating system in time, which may enhance the security of their smartphones and protect users' sensitive information better.
