Abstract (in Japanese) (See Japanese page) 
(in English) To improve the accuracy of the dynamic biometric authentication, it is desirable to be able to absorb the fluctuation of biometric information itself. To achieve this, the authors have proposed to apply a structure of the differential amplifier to the biometric authentication. More specifically, we aim to absorb the fluctuation of biometric information by taking a difference or a ratio of two biometric information measured at different places/states. This paper investigates to explain the mechanism how to absorb a common mode fluctuation by taking the ratio of two biometric information of complex numbers. Besides, we try to analyze the operating principle of a related biometric authentication method using the relational operation (a simplified inner product operation) of two local higher-order moment spectra features, by comparing it with our proposed method.
