Abstract
Method and apparatus are provided for authenticating a user. The method includes detecting a path of a finger movement of the user across a sensing surface, collecting a plurality of fingerprint images of the finger along the path of the finger movement, collecting a plurality of time stamps corresponding to the plurality of fingerprint images at different locations along the path, comparing the path of the finger movement to a previously enrolled path of finger movement using the plurality of fingerprint images and the plurality of time stamps corresponding to the plurality of fingerprint images collected, and authenticating the user based on the comparison.
Claims16
A method of authenticating a user, comprising:
- detecting a path of a finger movement of the user across a sensing surface;
- collecting a plurality of fingerprint images of the finger along the path of the finger movement;
- collecting a plurality of time stamps corresponding to the plurality of fingerprint images at different locations along the path;
- comparing the path of the finger movement to a previously enrolled path of finger movement using the plurality of fingerprint images and the plurality of time stamps corresponding to the plurality of fingerprint images collected;
- and
- authenticating the user based on the comparison.
An apparatus for authenticating a user, comprising:
- an image sensor configured to detect a path of a finger movement of the user across a sensing surface;
- a controller configured to collect a plurality of fingerprint images of the finger along the path of the finger movement, and collect a plurality of time stamps corresponding to the plurality of fingerprint images at different locations along the path;
- a memory configured to store the plurality of fingerprint images and plurality of time stamps corresponding to the plurality of fingerprint images;
- and
- the controller is further configured to compare the path of the finger movement to a previously enrolled path of finger movement using the plurality of fingerprint images and the plurality of time stamps corresponding to the plurality of fingerprint images collected, and authenticate the user based on the comparison.
