Abstract
Biometric identification system is used for the automatic identification of an individual based on the unique characteristics or features possessed by an individual. Many Biometric Technologies are available today. Iris Recognition System is the most reliable and accurate Biometric identification system available. Iris Recognition is the identification of an individual based on iris features. In the past few years many methods are used to improve the performance of iris recognition systems. These methods mainly focused on the robustness, accuracy and rapidity of iris recognition systems. The purpose of this technical report is for comparing different iris recognition systems based on their performance.
