Title: Fingerprint authentication device, biological finger determination device and biological finger determination method
Inventor: NIIZAKI TAKU
IPC: A61B5/117
Filed: 2006-03-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a fingerprint authentication device, a biological finger determination device and a biological finger determination method that can detect forgery even if a thin forged fingerprint formed from a gumdrop or the like is attached to the surface of a finger.  <P>SOLUTION: When a finger with a gumdrop fingerprint attached is placed on an input surface, the gumdrop fingerprint is formed in a thin layer between the input surface and the finger. Since the gumdrop is transparent, light radiated from a side light source passes through the thin gumdrop fingerprint layer, and even the light receiving element farthest from the light source detects the diffused light. On the other hand, since a finger without a gumdrop fingerprint attachment is not as transparent as the gumdrop, the light receiving element farthest from the light source does not detect diffused light. The different light transmission characteristics are used in a biological finger determination.  <P>COPYRIGHT: (C)2007,JPO&INPIT
