FAKE FINGER DETERMINATION APPARATUS AND FAKE FINGER DETERMINATION METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18349426 titled 'FAKE FINGER DETERMINATION APPARATUS AND FAKE FINGER DETERMINATION METHOD
Simplified Explanation
The present invention aims to improve the accuracy of detecting fake fingers used for fingerprint authentication.
- The invention involves attaching a transparent thin film to the surface of a finger to create a fake finger.
- It includes a mounting surface with an area to mount an authentication target, which is the object of fingerprint authentication.
- A transparent plate is provided on the mounting surface, defining the range of an image used to determine the authenticity of the authentication target.
- A light source is used to directly illuminate the authentication target mounted on the mounting area, bypassing the transparent plate.
- An imaging device captures an image of the authentication target through the transparent plate.
- The light emitting surface of the light source is positioned on the same plane as the mounting surface.
Original Abstract Submitted
The present invention improves an accuracy to discern a fake finger created by attaching a transparent thin film to the surface of a finger. The present invention has: a mounting surface that has a mounting area to mount an authentication target that is an object of fingerprint authentication; a transparent plate that is provided on mounting surface and defines a range of an image used for determining the authenticity of the authentication target; a light source that allows light to directly enter the authentication target mounted on the mounting area, not by way of the transparent plate; and an imaging device that images the authentication target mounted on the mounting area, by way of a the transparent plate, wherein a light emitting surface for emitting light of the light source to outside is disposed on the same plane as the mounting surface.
