Unimodal biometric has many problems like noisy data, intra class variation; inter class similarity, non-universality and spoofing which cause the system to be less accurate and secure. To overcome these problems and increase the level of security, biometric research enrolled multimodal biometrics into the field. Iris and palm print recognitions are considered to be the best recognition system since their false match and non-match rates are very small which implies high accuracy. Password hardening provides additional level of security provided to the template which in turn provides revocability.
