Iris Patterns As A Biometric Tool For Forensic Identifications: A Review

Resumo

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 micro-features of human iris. Several mathematical and statistical algorithms have been suggested for extracting and encoding iris minutiae used for pattern recognitions in automated systems. 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.
