PERSONAL AUTHENTICATION DEVICE AND MOBILE COMMUNICATION TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a biological authentication type personal authentication device which is small and thin and can accurately position a living body.

SOLUTION: The personal authentication device includes: first and second light sources which emit infrared rays; and a detection part which detects the infrared rays emitted from the first and second light sources onto the living body, and performs personal authentication by detecting an image including biological feature information by the infrared rays detected by the detection part. The personal authentication device positions the living body in a non-contact manner by detecting the positional information of the living body from the infrared rays emitted from the first and second light sources onto the living body and detected by the detection part.
