Abstract:

User authentication is an essential issue to smart terminal information security and privacy protection. Fingerprint authentication based on biometric features directly stores personal important features information on smart devices, which leads the risk of information leakage. Based on the characteristics of the gravity sensor in the smart terminal in the market, this paper uses the 3D accelerometer of the smart terminal to collect the user behavior data and identify the user. In order to improve the accuracy and efficiency of the recognition, the user can select any combination from the legal gesture library and use the combination as the authentication key (gesture key). Compared with the biometric-based authentication method, the authentication method based on user behaviors does not have the risk of revealing important personal characteristics, and avoids complicated knowledge passwords. Experimental results show that the proposed method has high recognition accuracy.

Key words: smart terminal, gravity sensor, identity authentication, gesture key
