Abstract
A device is not able to detect the forgery of a finger with high accuracy by the comparison of a reflected light image and a transmitted light image that are obtained from the same finger. A determination device is provided with an input element for receiving the reflected light image obtained by photographing a fingerprint of a finger with light reflected from the surface of the finger and the transmitted light image obtained by photographing the fingerprint of the finger with light transmitted through the finger, and a determination element for comparing the reflected light image and the transmitted light image, and outputting a real-forgery determination result of the fingerprint of the finger.

1-16. (canceled)
A determination device comprising:
- an input unit which receives a reflected light image obtained by photographing a fingerprint of a finger by light reflected by a surface of the finger and a transmitted light image obtained by photographing the fingerprint of the finger by light transmitted through the finger;
- and
- a determination unit which compares the reflected light image and the transmitted light image and outputting a real-forgery determination result of the fingerprint of the finger.
A determination device comprising:
- a means for receiving a reflected light image obtained by photographing a fingerprint of a finger by light reflected by a surface of the finger and a transmitted light image obtained by photographing the fingerprint of the finger by light transmitted through the finger;
- and
- a means for comparing the reflected light image and the transmitted light image and outputting a real-forgery determination result of the fingerprint of the finger.
A non-transient machine-readable medium which records a determination program causing a computer to carry out processing of receiving a reflected light image obtained by photographing a fingerprint of a finger by light reflected by a surface of the finger and a transmitted light image obtained by photographing the fingerprint of the finger by light transmitted through the finger, and outputting a real-forgery determination result of the fingerprint of the finger by comparing the reflected light image and the transmitted light image.
A determination method comprising:
- receiving a reflected light image obtained by photographing a fingerprint of a finger by light reflected by a surface of the finger and a transmitted light image obtained by photographing the fingerprint of the finger by light transmitted through the finger;
- comparing the reflected light image and the transmitted light image;
- and outputting a real-forgery determination result of the fingerprint of the finger.
