MagLive: Near-Field Magnetic Sensing-Based Voice Liveness Detection on Smartphones

arXiv:2404.01106v1 Announce Type: new
Abstract: Voice authentication has been widely used on smartphones. However, it remains vulnerable to spoofing attacks, where the attacker replays recorded voice samples from authentic humans using loudspeakers to bypass the voice authentication system. In this paper, we present MagLive, a robust voice liveness detection scheme designed for smartphones to mitigate such spoofing attacks. MagLive leverages differences in magnetic field patterns generated by different speakers (i.e., humans or loudspeakers) when speaking for liveness detection. It uses …
