While the move towards the digital era is being accelerated every hour, biometrics technologies have begun to affect people’s daily life more and more. Biometrics technologies verify identity through characteristics such as fingerprints, faces, irises, retinal patterns, palm prints, voice, hand-written signatures, and so on. These techniques, which use physical data, are receiving attention as a personal authentication method that is more convenient than conventional methods such as a password or ID cards. Biometric personal authenticcation uses data taken from measurements. Such data is unique to the individual and remains so throughout one’slife. This technology has been applied for controlling access to high-security facilities, but it is now being
widespread developed in information systems such as network, e-commerce, and retail applications. In these
technologies, iris recognition becomes the most mature and popular biometrics technology used in automatic
personal identification. In the beginning, the idea of using iris patterns for personal identification was originally proposed in 1936 by ophthalmologist Frank Burch. By the 1980's the idea had appeared in James Bond films, but it still remained science fiction and conjecture. In 1987 two other ophthalmologists..
