Abstract:
An individual authentication apparatus, comprising:a means for measuring acoustic characteristic information of an auditory organ wherein the means includes a sound sending part and a signal processing part for performing signal processing for sound information; and a means for authenticating individuals wherein the means comprises a storing part for storing acoustic characteristic information of an auditory organ collected in advance, and a signal processing part that compares the stored acoustic characteristic information and measured acoustic characteristic information, wherein the signal processing part for performing signal processing for sound information measures a difference of electrical characteristics of the sound sending part between one occasion when the sound sending part sends the sound to an open space and another occasion when the sound sending part sends the sound to a closed space in a manner that the sound sending part and the auditory organ of an authentication examinee are close to each other, as an acoustic characteristic information of the auditory organ.
