Human biometric features are considered unique, permanent, measureable and objective traits used as authentic tools for identification of an individual. Biometric authentications are increasingly utilized for identifying a genuine user or an imposter. The automated iris pattern recognition is based on the unique, non-intrusive and un-imitable microfeatures of human iris. Several mathematical and statistical algorithms have been suggested for extracting and encoding iris minutiae used for

Iris scanning is an easy and non-invasive technique, having comparatively lower false acceptance and rejection rates and negligible chances of manipulations and spoofing. Despite of some limitations, iris recognition is considered a promising advancement in forensic sciences. Present review has presented the iris recognition knowledge in nutshell to the readers. Absolute personal recognition is effectively required in many applications like secure access to buildings, sensitive premises (i.e., nuclear reactors, defense establishments) laptops, cellular phones, computer systems, ATMs etc. Biometric recognition or, simply, biometrics is the automatic recognition of individuals based on their physiological and/or behavioral characteristics like fingerprints, face, hand geometry, retina, ear, iris, speech, voice, signatures, handwriting, gait etc 1 . A biometric system first captures the data, removes the redundant features, constructs a template and compares it with other templates from a database in order to verify or identify an individual. Diversification of crime, criminal and criminality has invited the focussed
