Abstract
In this paper we propose liveness checking technique for
multimodal biometric authentication systems based on audiovisual mutual dependency models. Liveness checking ensures
that biometric cues are acquired from a live person who is
actually present at the time of capture for authenticating the
identity. The liveness check based on mutual dependency
models is performed by fusion of acoustic and visual speech
features which measure the degree of synchrony between the
lips and the voice extracted from speaking face video
sequences. Performance evaluation in terms of DET (Detector
Error Tradeoff) curves and EERs(Equal Error Rates) on
publicly available audiovisual speech databases show a
significant improvement in performance of proposed fusion of
face-voice features based on mutual dependency models.
