BIOMETRIC ENCRYPTED KEY SECURITY AND DIGITAL SIGNATURE WITH RSA

Abstract

The conventional methods of identification such as passwords, smart cards and personal
identification numbers (PINs) can be compromised, stolen or forgotten. Biometric is the only
way to uniquely identify an individual and hence used in many applications. The vulnerability
of biometric authentication systems to attacks is now a widely accepted fact. Biometric
encryption systems are more secure and are widely used in many information security
applications to conceal private keys by using biometric data. Major challenge that these
systems face is how to protect private keys from attackers. Integration of biometrics with public
key structure using biometric built signature key generation based on iris acknowledgement is
secure, convenient, and fast and correctly identifies the person. This paper will explore
integration of iris templates with two existing and widely used digital signature algorithm RSA.
Problems associated with this is discussed
