In music theory, the triton is defined as a musical interval composed of three adjacent whole tones(or six semitones), which generates a harmonic and melodic dissonance. The triton paradox is an auditory illusion which is heard as ascending by some people and as descending by others. In this paper we examine an emerging non-static biometric technique that aims to identify users based on analyzing uniqueness and consistency through the user experiences. We also propose some authentication schemes which provides protection against key logging, shoulder surfing, and brute force attacks.
