20110057775 | BIOMETRIC AUTHENTICATION DEVICE - Disclosed herein is a biometric authentication device. The biometric authentication device includes a main body for forming a hand grip surface and constituting an entire framework of the biometric authentication device. At least one light source is disposed on one side of the main body and configured to radiate light. A reflection unit is included in the main body and attached to a side opposite that of the light source, the reflection unit allowing the radiated light to be incident on a hand and re-reflecting light that is incident on and reflected from the hand. An imaging device is disposed on the side of the main body, which is identical to the side on which the light source is disposed, and is configured to acquire biometric information of the hand by forming images of re-reflected light. An authentication/verification unit performs personal authentication using the biometric information. | 03-10-2011 |
20110063077 | VEIN AUTHENTICATION APPARATUS USING TOTAL INTERNAL REFLECTION - Disclosed herein is a vein authentication apparatus. The vein authentication apparatus includes a protective panel provided with a finger-resting surface, a light entry hole and a light exit hole and configured to totally reflect light, a light source located adjacent to the light entry hole of the protective panel and configured to emit the near infrared rays, an imaging element located adjacent to the light exit hole of the protective panel and configured to acquire a vein pattern, a light entry-side diffraction element located in the light entry hole of the protective panel and configured to guide the light toward the fingertip, a light exit-side diffraction element located in the light exit hole of the protective panel and configured to guide the light toward the imaging element, and an authentication unit configured to perform vein authentication using the vein pattern. | 03-17-2011 |
20110063430 | BIOMETRIC AUTHENTICATION DEVICE - Disclosed herein is a biometric authentication device. The biometric authentication device according to the present invention is configured such that it blocks visible light using an authentication button, the inside of which is opened or closed by a finger so as to realize the small size and slim shape of a biometric authentication device, and blocks infrared light or allows infrared light to pass while a driving unit moves vertically or horizontally by the operation of the authentication button. Accordingly, in the biometric authentication device, a camera module captures a normal image in normal mode, and captures an infrared pattern reflected from a finger in a vein authentication mode to perform biometric authentication. | 03-17-2011 |
