BioCryptosystems for Authentication and Network Security-A Survey
K Saraswathi, R. Balasubramaniam · 2010
Authentication and Network security prove to be challenging issues in data transmission between users. A number of proposed bio-crypto algorithms have limited practical applicability because of trade-off that exists between recognition performance and security of the biometric template. Most of the traditional cryptosystems that have been proposed earlier in literature have adopted secret key to authenticate the user information. The use of secret key may direct to unenviable circumstances when the secret key is lost, stolen or forgotten. This obviously makes the user to obscure their authentication and security. These controversies can be eliminated by introducing new algorithms for providing authentication based on biometrics (characterizes on physiological and behavioral traits of persons). Most of the current authentication systems are based on biometrics like fingerprint, retina, face recognition, etc. This paper generally revolves around various methods that are adopted to ensure user authentication and network security by binding a cryptographic key with a biometric template of the user. The security level is trusted since the cryptographic key cannot be exposed unless successful biometric authentication. This paper also overviews on issues in cryptographic key generation due to flawed nature of biometric feature extraction and matching algorithms.
