Biometrics gives a lot of methods in high-secure applications while using natural, user-friendly and fast authentication. Cryptography is intended to ensure the secrecy and authenticity of message. The cryptographic key will be long, so it is difficult to remember, protecting the confidentiality of the cryptographic keys is one of the significant issues to be deal with. This can be efficiently solved by the integration of biometrics with cryptography. Conventional techniques depend on biometric features like face, fingerprint, hand geometry, iris, signature, keystroke, voice and the like for the extraction of key.
