| 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.
