The rich random pattern visible in the iris of the eye represents one of the strongest biometric characteristics and considerable research efforts are being invested to push forward iris recognition technologies. Numerous covariates of iris recognition are the focus of current research programmes, which aim at improving different key factors of iris biometric system, e.g., usability, acceptability or interoperability. This chapter provides a very brief overview of the processing chain of generic iris recognition systems as well as a the current state-of-the-art. Furthermore, current challenges in the field of iris recognition were touched upon.
