Abstract : The growing vastness of identity theft in our society has made the requirement of reliable information security mechanisms a priority. Even though information security can be accomplished with the help of a prevailing tool like cryptography, protecting the confidentiality of the cryptographic keys is one of the significant issues to be deal with. This predicament can be efficiently solved by the integration of biometrics with cryptography. Of late, the enhanced performance of cryptographic key generated from biometrics in terms of security has obtained massive reputation amongst the researchers and experimenters. However, there is a permanent association between the biometric and the user, in which modification is impossible. Hence, the biometric is gone eternally and possibly for all the applications which apply it, if there is a compromise of the biometric identifier. This may be solved by the construction of revocable biometric templates through cancelable biometrics. In this paper, we have proposed an approach to generate irrevocable cryptographic key from cancelable fingerprint templates, which performs in an efficient manner. Initially, the fingerprints are employed to extract the minutiae points which are transformed in an efficient manner to obtain deformed points. Subsequently, the deformed points are employed to generate the cancelable templates which are utilized for the extraction of irrevocable keys. It is highly impractical to acquire cancelable fingerprint templates and original fingerprints from the generated key owing to the fact that cryptographic key generated is irrevocable. We have utilized the fingerprints accessible from open sources to evaluate the efficacy of our approach. In addition, the protection analysis of the proposed method has been presented.
