Document Type and Number:
WIPO Patent Application WO/2008/015956
Kind Code:
A1
Abstract:
Reliable biometric personal authentication is realized by using the sound spectrogram, especially the external auditory canal sound produced in the closed external auditory canal. The external auditory canal sound confirmed by acoustical analysis of the phonetic quality of the external auditory canal produced in the closed external auditory canal and the phonetic quality of the oral sound produced from the mouth is used as a sound spectrogram for biometric authentication. Sound spectrogram confirmation for checking the similarity between the electronic data collected from the external auditory canal confirmed by the acoustic analysis and the electronic data stored in storage means of a computer system is conducted. If the similarity agrees or the difference is small, the person to be authenticated is authenticated.
