Iris recognition is an advanced biometric identification technique that uses the unique patterns of the human iris to verify identity with remarkable accuracy, speed, and security. The iris, located between the pupil and the sclera, contains intricate and stable patterns formed during early childhood and remaining unchanged throughout a person’s life. These characteristics make iris recognition one of the most reliable biometric modalities, surpassing fingerprints and facial recognition in several aspects. Its non-intrusive nature, contactless capture, resistance to environmental effects, and incredibly low false-match rates have made it a preferred solution in sectors where precision and security are essential. While the technology has long been used in high-security environments, recent advancements in imaging, artificial intelligence, and mobile hardware have broadened its applications across consumer devices, public services, and digital authentication ecosystems.
Iris recognition begins with the image acquisition process, which involves capturing a high-resolution photo of the subject’s eyes using…
