    • A method and apparatus are disclosed that authenticate a user of a mobile device with motion sensors. During a learning session, the user initializes the mobile device by providing a motion sample. The mobile device extracts motion features that are unique to the user and converts them to parity bits and to a password shadow. During a recognition session, a motion pattern is gathered from the user moving the mobile device as if it were a virtual pen. The mobile device then uses the stored parity bits to correct small differences between motion patterns exhibited by the same user at different times. The mobile device converts the corrected motion pattern into a motion password that is compared with the stored password shadow. A user is authenticated only if the two values coincide. The system erases the generated motion password.
    • 公开了一种使用运动传感器认证移动设备的用户的方法和装置。 在学习会话期间,用户通过提供运动样本来初始化移动设备。 移动设备提取用户所特有的运动特征并将其转换为奇偶校验位和密码阴影。 在识别会话期间,从移动移动设备的用户收集运动模式,如同它是虚拟笔。 然后,移动设备使用所存储的奇偶校验位来校正在不同时间由相同用户显示的运动模式之间的小差异。 移动设备将校正的运动模式转换成与存储的密码阴影进行比较的运动密码。 仅当两个值相符时,用户才被认证。 系统会擦除生成的运动密码。
