Generate a key for MAC Algorithm using Biometric Fingerprint

One of Authentication technique involves the use of a secret key to generate a small fixed size block of dataknown as cryptographic checksum or MAC that is appended to the message. The unauthorized thefts in our society have made the requirement for reliable information securitymechanisms. Information security can be accomplished with the help of a prevailing tool like cryptography, protecting the cryptographic keys is one of the significant issues to be deal with. Here we proposed abiometric-crypto system which generates a cryptographic key from the Finger prints for calculating thMAC value of the information we considered fingerprint because it is unique and permanent through out aperson’s
