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 current path of a movement of a finger of the user across a sensing surface;
- comparing the current path of the finger movement to a previously enrolled path of finger movement, wherein each of the current path and the previously enrolled path includes a plurality of fingerprint images comprising at least one flat fingerprint image produced by motions of sliding and at least one rolled fingerprint image produced by motions of rolling of the finger and a plurality of time data including time stamps corresponding to the plurality of fingerprint images at different locations along the respective path, and wherein said comparison is performed using the fingerprint images and the corresponding time data;
- and
- authenticating the user based on the comparison, wherein the authenticating of the user occurs continuously at the plurality of time data corresponding to the current path as the finger moves on the sensing surface.
An apparatus for authenticating a user, comprising:
- an image sensor configured to detect a current path of a movement of a finger of the user across a sensing surface;
- a memory configured to store a plurality of fingerprint images and a plurality of time data corresponding to the current path;
- and
- a controller configured to compare the current path of the finger movement to a previously enrolled path of finger movement, wherein each of the current path and the previously enrolled path includes the plurality of fingerprint images comprising at least one flat fingerprint image produced by motions of sliding and at least one rolled fingerprint image produced by motions of rolling of the finger and the plurality of time data including time stamps corresponding to the plurality of fingerprint images at different locations along the respective path, and wherein said comparison is performed using the fingerprint images and the corresponding time data;
- and, and authenticate the user based on the comparison, wherein the authenticating of the user occurs continuously at the plurality of time data corresponding to the current path as the finger moves on the sensing surface.
