The use of biometrics for user authentication has recentlyattracted attention. Biometrics makes it possible to authenticate aperson accurately, but biometric information can easily be leakedand/or copied. It is therefore desirable to devise biometricauthentication that does not require biometric information to besecret. This paper proposes a user authentication method thatutilises human reflex responses. The expectation is that, even if aperson's reflex characteristics are publicly known, it would bedifficult for someone else to impersonate that person, since humanbeings are basically unable to control their own reflexes. In thispaper, we demonstrate user authentication using blind spot positionand saccade responses as the prototype of a system ofauthentication based on reflex responses, and also study thefeasibility of such a system.
