Biometric methods and systems for enrollment and authentication

摘要

Biometric methods for enrollment and authentication of a person. During authentication, a previously stored enrollment image is presented on a display to the person. A candidate person is instructed to present a body part to a camera while the person is holding the body part unsupported in free space with respect to the camera. Using the camera, a candidate image of the body part is captured and presented with the previously stored enrollment image. The candidate person aligns the candidate image with the previously stored enrollment image. On alignment, the candidate image is verified as an authentic image of the person and the candidate person is authenticated as the person previously enrolled.
