Abstract: A processor fingerprint enrollment method and apparatus is disclosed. A processor implemented fingerprint enrollment method includes performing a matching between a received input fingerprint image of a user and one or more enrolled fingerprint images, and selectively, based on a result of the matching identifying a matched enrolled fingerprint image from the one or more enrolled fingerprint image and based on a calculated degree of diversity in the fingerprint corresponding to an overlapping region between the input fingerprint image and the matched enrolled fingerprint image, storing the input fingerprint as another enrolled fingerprint image.

Abstract: A method and apparatus for authenticating a user using a vein pattern are provided that project a near infrared (NIR) ray toward a skin of the user using a light emitting diode (LED), where the user is adjacent to a terminal including the LED. An image sensor receives a light reflected by the skin, generates a vein pattern of the skin based on an image generated using the received light, and authenticates the user as a registered user of a pre-stored vein pattern when the generated vein pattern matches the pre-stored vein pattern.
