A biometric is a unique feature, a measurable trait or characteristic which is utilized in automatically identifying or verifying the identity of a human being. An assortment of inevitable shortcomings has been faced by unimodal biometric recognition like Limited discriminability, noisy biometric data, upper bound in performance and lack of permanence, consequence dilapidation of exactness and performance of the system. Multimodal biometrics consolidates the two or more biometric features into a single detection. Problems transpired in unimodal recognition can be alleviated by using multimodal biometric systems that fuse evidence from scores of multiple biometric systems and characteristically provide better recognition as compared to unimodal biometric systems.
