Intensification of security in 2-factor biometric authentication system

Biometrics deals with computerized methods of certifying the identity of a person based on physiological or behavioral characteristics. The possibility of two users having the same identification features in the biometric system is virtually zero. Biometric identification delivers extremely accurate and secure access to information. In the conventional biometric system, privacy is not maintained as data is on single server. This issue is handled in the proposed system by combining biometric with visual cryptography. This system contains two biometric characters, fingerprint and iris to have more secured system. Fingerprints and iris scans produce unique data sets. The intent to implement these methods is to enhance the security infrastructure by reducing the space complexity of database. The experimental results show high accuracy and high security of implemented system.
