<p>We provide quite a novel personal authentication system using heart sound waveform and/or breathing waveform pattern which promptly judges personal authentication of a person to be authenticated with a very high degree of accuracy. The personal authentication system is comprised of a waveform detection means which detects a heart sound waveform pattern and a means which compares a heart sound waveform pattern detected by the waveform detection means with a previously registered heart sound waveform pattern. If the detected heart sound waveform pattern coincides with the registered heart sound waveform pattern, the system authenticates the person to be identical. In such constitution, the system can check the autonomic heart sound which cannot be controlled by a personal will based on the previously registered heart sound waveform pattern in real time, and performs personal authentication of the person to be authenticated with very high accuracy promptly.</p> |
