In the world of modern communication, securing information is a very important task. Hence Cryptographic systems are integral parts of communication systems in majority applications. Security requirements demand that these systems need to be operated with large secret keys. Since it is very difficult to remember large private keys, these keys are replaced by biometric features and this is called biometric security.
