Abstract

An identification information creation apparatus and method capable of improving reliability in an identification process. A prescribed number or fewer isolated pixels are eliminated as condition noises from a binarized image created from images obtained by imaging blood vessels unique to a body, and identification information is created based on the blood vessels of the resultant noise-free binarized image. This can reduce a possibility of creating the identification information with the condition noises as a part of the blood vessels, thus making it possible to prevent the identification information from deteriorating due to different imaging conditions and physiologic change of imaging target and thus improving reliability in the identification process.
