User authentication scheme using individual auditory pop-out

Abstract

This paper presents a user authentication scheme which takes advantage of the uniqueness of prover's auditory characteristics. In this scheme, several audio stimuli are presented at the same time by headphone. The stimuli include a special audio stimulus that only the genuine prover can easily distinguishes from other stimuli because of the uniqueness of auditory characteristics. The prover is made to answer the contents of the special stimulus. The verifier confirms the correct answer as the genuine prover. As the special audio stimulus that distinguishes the genuiness, auto-phonic production is examined in this paper. The advantage of this scheme is that the prover does not need to keep complex sequence in minds like a password authentication. Moreover, the Personal Authentication Information (PAI) is never stolen, because the PAI in this scheme is personal auditory memory or receptor. © 2008 Springer-Verlag Berlin Heidelberg.
