Abstract: The Unimodal biometrics has many problems such as noisy data, intra-class variations, confined degrees of freedom, non uniformity, spoof attacks, uniqueness and diverseness, non invariant and spoofy attack. The use of single property works as exclusive source of information for authentication (e.g. fingerprint, face, voice, gait etc.) generally leads to high false acceptance rate (FAR) and false rejection rate (FRR), Failure to Enroll rate (FER). . In order to conquered the limitations provided by unimodal system there is need of system which can combine of two or more attributes types of biometrics systems known as multimodal biometric systems. These systems are more authentic and trustworthy due to the presence of multiple, self contained, individualistic biometrics attributes. The spoofing problem is solved easily because it is very difficult for deceiver to take-off multiple biometric traits. The advantages of multimodal biometric systems are that there are multiple sources of information. As multimodal biometric systems use more than one biometric trait so it provide more security and more reliable and provide maximum accuracy.
