ABSTRACT
In the present age of digital impersonation, biometrictechniques are being used increasingly to prevaricateagainst identity thefts. Iris recognition is a proven,accurate means to identify people. Iris is regarded as themost reliable biometric feature in terms of its uniquenessand robustness. The objective of this work is to present abiometric authentication system for high securityphysical access control based on iris pattern. Theproposed iris recognition with improvement in segmentation and matching stages using Hamming distance provides match for iris pattern if hamming distance is below 0.15. The CASIA IRIS image database of Chinese Academy of Sciences Institute of Automation is used and the system is implemented in MATLAB. The proposed approach found to report higher verification accuracy of 99.2%.
