Mobile Payment Authentication

The user’s behavior features are unique and hardly to be imitated, identity authentication based on user behaviors has become a research hotspot. However, none of the existing research has considered the influence of user posture on users’ gesture behavior authentication. In order to make the identity authentication method adapt to the use of the application in different postures, this chapter presents a touch screen behavior authentication system based on user gestures. We collect the user’s gesture behavior data through the touch screen of the mobile phone, collect the user’s posture behavior data through the mobile phone’s orientation sensor and acceleration sensor, and finally extract the user’s posture behavior features and gesture behavior features. In addition, based on this authentication system architecture, we respectively provide two forms of authentication model construction methods: login authentication and continuous authentication. It is possible to monitor from user login to the entire usage process for improving the payment security of mobile devices by using login authentication and continuous authentication comprehensively.
