Executive Summary

This paper puts forth a fresh methodology for the se-cure storage of fingerprint template by generating Secured Feature Matrix and keys for cryptographic techniques applied for data Encryption or Decryption with the aid of cancellable biometric features. Conventional techniques depend on biometric features like face, fingerprint, hand geometry, iris, signature, keystroke, voice and the like for the extraction of key information. If a Biometric Key is missing or stolen, it is lost perpetually and possibly for every application where the biometric is utilized, since a biometric is permanently linked with a user and cannot be altered.
