Biometric-information processing device, method of processing biometric information, and computer-readable recording medium storing biometric-information processing program

摘要

A biometric-information processing device includes an image acquisition unit configured to acquire an image of a biometric object using light reflected from the biometric object. The biometric-information processing device further includes an extracting unit configured to extract a frequency component having a frequency higher than a predetermined spatial frequency at the image acquired by the image acquisition unit.

主权项

1. A biometric-information processing device comprising:
a sensor configured to acquire an image of a biometric object using light reflected from the biometric object; and a processor configured to extract a frequency component having a frequency higher than a predetermined spatial frequency at the image, wherein the processor is further configured to carry out authentication processing using the image acquired by the sensor to determine a first index value of a surface reflection component of the biometric object from the frequency component extracted by the processor and to determine whether the authentication processing is to be carried out on the basis of the first index value, and wherein the frequency component is extracted from a light reflected at a surface of the biometric object, and is separated from another light reflected at a vein in the biometric object.
