Biometric systems are automatic process to identify a person through physical traits or to verify his/her identity. Various systems were implemented and used over years, and they include systems based on fingerprints, irises, facial images, hand geometry, and speaker recognition. For successful implementation of biometric systems, it is required to address many issues like accuracy, efficiency, robustness, applicability, and universality. Single modality based recognition verification s not very robust while combining information from various biometric modalities provides better performance.
