A Highly Secure Integrated Biometrics Authentication Using Finger-Palmprint Fusion

Biometric authentication is the verification and identification of a person uniquely based on physical characteristics such as finger print, palm print, retina, iris, face etcetera or behavioral characteristics such as signature, gait, typing patterns, voice etcetera. Existing single modal biometric system has more error rate and provides less security than the combined one. To reduce the error rate and overcome the security flaw, multimodal biometric systems are used. Finger print is the most widely used technique and easy to use[3]. Palm print is more secure than finger print as it has more features like principal lines, wrinkles, texture, indents and marks compared to finger print and not available in public like photographs from which fake face or iris can be created. This paper presents a highly secure low cost biometric authentication scheme which makes use of both finger print and palm print features by fusing them for high level authentication. From the result it is concluded that the proposed scheme is highly secure, more economic, and user friendly. More over it has less error rate and high accuracy and offers better authentication.
