An Introduction to the IrisCode Theory

IrisCode is the most successful iris recognition method. Developed for over 18 years, IrisCode still dominates the market even though numerous iris recognition algorithms have been proposed in the academics. Currently, more than 60 million people have been mathematically enrolled by this algorithm. Its computational advantages, including high matching speed, predictable false acceptance rates, and robustness against local brightness and contrast variations, play a significant role in its commercial success. To further these computational advantages, researchers have modified this algorithm to enhance iris recognition performance and recognize other biometric traits (e.g., palm print). Many scientific papers on iris recognition have been published, but its theory is almost completely ignored. In this chapter, we will report our most recent theoretical work on the IrisCode.
