Biometric authentication device and biometric authentication method
First Claim
1. A biometric authentication device, comprising:
- an operation panel configured to input identifying information of a user;
a camera configured capture an image of a user'"'"'s hand a plural number of times; and
one or more processors configured to;
extract vein information, on a per image basis, of the hand image captured by the camera and execute a matching process of matching the vein information with previously-provided vein data associated with the identifying information;
acquire determination data specifying, based on a thickness of a vein in a predetermined position in the hand image, whether the hand image is acquired by capturing a living organism or not; and
authenticate the user when a matching result of the matching on the per hand-image basis demonstrates its normality and the determination data demonstrates that the hand image is acquired by capturing the living organism, or does not authenticate the user.

Abstract
A biometric authentication device is provided with an input section for inputting identification information relative to a user, an imaging section which captures images of a hand of the user a plurality of times; a matching section which extracts vein information from each image of the hand captured by the imaging section and collates the vein information with prepared vein data corresponding to the identification information; a judgment data generation section which obtains data for judgment indicating whether the image of the hand is obtained by capturing the images of a living body, on the basis of the image of the hand; and a judgment section which authenticates the user when the result of the matching by the matching section relative to each image of the hand indicates normality and the data for judgment indicates that the image of the hand is obtained by imaging the living body, but which otherwise does not authentication the user.

5. A biometric authentication method, comprising:
-
accepting an input of identifying information of a user; capturing an image of a user'"'"'s hand a plural number of times; extracting vein information, on a per image basis, of the hand image captured in the capturing and executing matching the vein information with previously-provided vein data associated with the identifying information; acquiring determination data specifying, based on a thickness of a vein in a predetermined position in the hand image, whether the hand image is acquired by capturing the living organism or not; and authenticating the user when a matching result in the matching step on the per hand-image basis demonstrates its normality and the determination data demonstrates that the hand image is acquired by capturing the living organism, or not authenticating the user. - View Dependent Claims (6, 7, 8)

9. A biometric authentication device, comprising:
-
an operation panel configured to input identifying information of a user; a camera configured to capture an image of a user'"'"'s hand; and one or more processors configured to; extract vein information of the hand image captured by the camera and execute matching the vein information with previously-provided vein data associated with the identifying information; measure a thickness of a vein in a predetermined position on hand images each of which is captured on different time; and authenticate the user when a matching result of the matching on the per hand-image basis demonstrates its normality and the thickness of the vein in the predetermined position shows a time-based variation between the hand images.
