In today's networked world the need for security systems are growing due to increase in crimes like computer hacking, illegal access of ATM &cell phone and security breaches in govt. and private buildings. Criminals take advantage of fundamental flaws in the conventional security systems. For these security issues biometric recognition system are used for personal identification. Biometrics of individual can't be hacked easily rather than password, personal identification no., smart card etc. Multimodal system can combine any number of independent biometrics and overcome some of the limitations presented by using just one biometric as the users' verification tool. The fusion of multiple biometrics helps to minimize the system error rates. Fusion methods include processing biometric modalities sequentially until an acceptable match is obtained.
