论文摘要
耳声认证是一种新的生物识别方法，它利用用户之间耳道的声学特征的差异。但是，关于导致声学特征差异的因素的报道很少。我们根据用户对用户相似性研究了耳道形状与声学特征之间的关系。我们使用磁共振成像（MRI）测量耳道几何形状。结果，形状相似性和声学特征相似性之间的相关系数高于0.7，确定系数高于0.5。这表明耳道形状的差异是重要因素之一。
Ear acoustic authentication is a new biometrics method and it utilizes the differences in acoustic characteristics of the ear canal between users. However, there have been few reports on the factors that cause differences in the acoustic characteristics. We investigate the relationship between ear canal shapes and acoustic characteristics in terms of user-to-user similarity. We used magnetic resonance imaging (MRI) to measure ear canal geometry. As a result, the correlation coefficient between shape similarity and acoustic characteristic similarity is higher than 0.7 and the coefficient of determination is higher than 0.5. This suggests that the difference in the shape of the ear canal is one of the important factors.
