在前人研究的利用耳道声学特性(耳廓相关传递函数)进行的个人认证中，在使用耳机和耳机的情况下获得了较高的认证率。另一方面，在使用不覆盖外耳或耳道的手机的情况下，认证率低于其他设备。然而，手机不需要任何其他设备来测量声学特性，因为内置了微型扬声器和麦克风。这对于使用PINNA相关传递函数的高度方便的认证系统来说是一个重要的点。本文利用手机测得的耳廓相关传递函数来研究认证率。
In the personal authentication using acoustic properties of ear canal (pinna related transfer function) by previous study, the high authentication rate was obtained in the case of using the earphone and the headphone. On the other hand, in the case of using mobile phone, which does not cover the outer ear or canal, the authentication rate is lower than that of other devices. However, the mobile phone does not require any other equipment for measuring acoustic properties because micro speaker and microphone are built in. This is an important point for the highly convenient authentication system using the pinna related transfer function. In this paper, the authors investigate authentication rate using the pinna related transfer function measured by the mobile phone.
