The object of the present invention is to provide an individual authentication method and apparatus that use no bulky apparatuses, are insusceptible to forgery, and use an auditory organ which is almost independent of health condition and aging, is little subject to physiological rejection, and exists in everyone. To achieve this object, the present invention comprises a sound receiving/sending part, a signal processing part for performing signal processing for information of sound to be received and sent, a storing part for storing acoustic characteristic information of an auditory organ, and a signal processing part that controls sound receiving and sending, and saves, compares and identifies acoustic characteristic information, whereby whether an authentication examinee is one of authentication subjects can be determined by comparing acoustic characteristic information of an auditory organ collected in advance and acoustic characteristic information of an auditory organ measured in the authentication examinee.
