Bi-modal biometric authentication on mobile phones in challenging conditions ?
We examine bi-modal (face/speaker) authentication in challenging mobile environment. We release new protocols (and data) with significant mismatch conditions (MOBIO). We study bi-modal and multi-algorithm fusion using generative modelling techniques. Multi-algorithm and multi-modal fusion provides a consistent performance improvement. The proposed bi-modal system significantly outperforms the state-of-the-art.
