The biometric based personal authentication method is a technique used for computing and analyzing the physical and/or behavioral characteristics of the person. In future the biometric system may provide an alternative of digital solution to the ID cards, passwords, driving licenses, passports, etc. Nowadays the researcher and scientist are given interest on multimodal biometric because multimodal biometric gives more security and reliability over the single biometric technique. In this book, we proposed a multimodal biometric technique based on palm and fingerprint.
