Outline of Final Research Achievements

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, I propose to apply a structure of the differential amplifier to the biometric authentication. More specifically, I aim to absorb the fluctuation of biometric information by taking a difference or a ratio of two biometric information measured at different places/states. As a first attempt, I develop an authentication method using a ratio of blood flows in two places of blood vessels.
