The procedure by which a person's identity can be authenticated by applying the physical or behavioral trait is called Biometric. Physical traits, similar to fingerprints, face, iris and so on depend on physical characteristics which are by and large inborn and stable. Behavioral traits, similar to voice, signature or keystroke and so on then again, is a quantifiable characteristic. That is acquired after some time and is liable to think change. Unimodal biometric systems created for each of these biometric features may not generally meet the required performance. The techniques are broke down to incorporate the different features together to obtain a multimodal biometric system. The current research uncovers that multimodal biometric system is more viable in authentication. The goal of this paper is to highlight the significance of the utilization of multimodal biometrics in the area of secure individual confirmation. This paper gives an alternate discernment to utilize biometrics as a largest amount of system security with the combination of numerous biometric modalities.
