Making Biometric System More Robust With Multibiometrics
A biometric system is a pattern recognition system that makes a personal verification and identification by establishing the authenticity on the basis of a particular physiological or behavioral characteristic possessed by the user. Biometrics provides a better solution for increased security requirements and privacy protection than traditional recognition methods such as passwords and PINs. Biometric systems that use a single biometric trait to establish identity are unimodal biometric systems. Various limitations imposed by these biometric systems are noisy data, non-universality, intra-class variations, inter-class similarities and spoof attacks.
