Nowadays, with the prosperous development of smartphone, abundant applications in smartphone have sprung up. To secure privacy information of users from being leaked, user authentication become necessary and important. Traditional authentication scheme such as password are vulnerable to shoulder surfing attacks and smudge attacks. Physiological biometric authentication schemes usually have some limitations when people using. More importantly, once the physiological information leaked will cause serious consequences. In contrast, behavioral biometric authentication schemes are secure and convenient. In this paper, we propose a handy user authentication scheme by simply turning over the phone. The scheme uses embedded motion sensors to effectively capture the unique user behavior. We recruited 19 volunteers with about 760,000 turning samples collected over multiple weeks under sitting and standing postures. Eventually, the scheme we proposed is available to use and deploy in smartphone.
