he use of biometric technologies in large scale systems like voter registration, border control, national ID cards etc. is increasing around the world. Such systems are not powered by a single biometric technology; rather they employ multimodal biometric systems to ensure better performance and higher enrollment rates. Several US government systems use a combination of fingerprint, face and iris recognition in systems which manage millions of identities. While the benefits of such systems is evident, extracting optimal performance requires more than just a knowledge of each individual biometric technology. This webinar will discuss the benefits and drawbacks of multimodal biometric systems, best practices on designing and deploying multimodal biometric systems, and how multimodal biometric systems are being used in operational systems.
