    • A computing device implemented method is provided for authenticating a user. In the method, a computing device may capture a gesture of the user with a sensor of the computing device as a sequence of captured sensor readings sampled in time. Each captured sensor reading may be compared with a corresponding reference sensor reading of a reference gesture to determine whether the captured sensor reading falls within a reference uncertainty range from the corresponding reference sensor reading. When the captured sensor reading falls within the reference uncertainty range, the device may include an information content value associated with that reference sensor reading in a threshold calculation. The device may authenticate the user when a sum of the included information content values exceeds a threshold value. A computing device may also be provided, the computing device operative to carry out the method.
    • 提供了一种用于认证用户的计算设备实现方法。 在该方法中,计算设备可以使用计算设备的传感器捕获用户的手势作为在时间上采样的所捕获的传感器读数的序列。 可以将每个捕获的传感器读数与参考手势的对应参考传感器读数进行比较,以确定所捕获的传感器读数是否落入相应参考传感器读数的参考不确定范围内。 当捕获的传感器读数落在参考不确定性范围内时,该装置可以包括在阈值计算中与该参考传感器读数相关联的信息内容值。 当所包含的信息内容值的总和超过阈值时,设备可以认证用户。 还可以提供计算设备,该计算设备可操作地执行该方法。
