An Effective Symmetric Key Based Network Security Framework –Aided by Crypto Biometrics


     

   Subscribe/Renew Journal


This work addresses all the concerns in traditional crypto biometric systems such as privacy of biometrics, sharing of biometrics between communicating parties, generating revocable key from irrevocable biometric, unwanted processing of low quality inputs etc. It uses fingerprint as basic biometric and acquires it from sender and receiver simultaneously. This is processed and its quality is determined. Feature extraction is done for good quality input data and transformations are made on it on both sides, exchanged through a novel key base steganography. The templates are fused and shuffled thus providing a provision for revocability. Since neither the final cryptographic key nor the original fingerprint is being stored there is no need of any kind of database security. Processing time is substantially reduced by the filtering, thus advocating an important issue in all classical crypto biometric systems. It also throws light on to extending the work for multiple sender/receiver systems with the same kind of biometric bindings, safety and security.

Abstract


This work addresses all the concerns in traditional crypto biometric systems such as privacy of biometrics, sharing of biometrics between communicating parties, generating revocable key from irrevocable biometric, unwanted processing of low quality inputs etc. It uses fingerprint as basic biometric and acquires it from sender and receiver simultaneously. This is processed and its quality is determined. Feature extraction is done for good quality input data and transformations are made on it on both sides, exchanged through a novel key base steganography. The templates are fused and shuffled thus providing a provision for revocability. Since neither the final cryptographic key nor the original fingerprint is being stored there is no need of any kind of database security. Processing time is substantially reduced by the filtering, thus advocating an important issue in all classical crypto biometric systems. It also throws light on to extending the work for multiple sender/receiver systems with the same kind of biometric bindings, safety and security.
