Abstract
A biometric system is basically a pattern recognition system. Biometrics based user authentication system serve as a reliable means for meeting the challenges in today‟s world of information and network security. It has gained enormous interest by scientists and researchers. Unimodal biometric systems that employ only a single biometric trait fails to achieve the desired security levels. Even the best unimodal biometric system suffers from various problems. To overcome these issues, we propose a multi-modal biometric system which employs iris and hand-geometry biometric traits. The iris patterns of human eye are very complex and random. It is almost impossible for an imposter to imitate them. Handgeometry measurements are not so distinctive and hence are used only for verification purpose. By combining them with other biometric trait like iris, a more secure multi-biometric security system can be obtained for verification as well as identification purpose. In this paper we will present a brief
