A detailed comparative study could particularly provide an overview for the readers. There is a need to highlight and analyze the work done by different authors related to iris studies, methodologies, and practices. This presented iris recognition as a very clear and effective concept. In recent years, a good amount of research is made regarding the evolution of biometric-based on the iris.
Iris has become a very effective recording of its superior properties, such as reliability and accuracy. The general method of the iris recognition system includes image acquisition, segmentation, feature extraction, matching, and classification. Iris recognition is one of the authentication methods that uses high-resolution assisted pattern recognition technology.
The iris has a unique structure that remains stable throughout a person’s life. Specifically, in the past decade, iris recognition technology has become the most popular biometric technology for human authentication and recognition due to its stability and uniqueness in its structure. There are various kinds of biometrics being used, these include Fingerprint, Face, Speaker/Voice, Infrared thermogram (facial, hand, or hand vein), Gait, Keystroke, Odor, Ear, Hand geometry, Retina, Iris, Palmprint, Signature, DNA, Knuckle crease, Brain/EEG, Heart sound/ECG. Numerous methods, techniques, and systems on biometrics serve sciences, security, military, medical area, and human identification. Specifically, automation culture has desired to design and launch automated systems for highly reliable and accurate human authentication and identification.īiometrics has been deployed successfully in various fields of real life. In the smart world today, the importance of technological solutions in biometrics is growing. Such systems effectively help to overcome the security issues affecting the conventional methods of personal authentication. The biometric systems use unique human physiological and anatomical properties to define details. Biometrics refers to specific physiological and/or behavioral (extrinsic and/or intrinsic respectively) characteristics that are uniquely related to a person. Biometrics is the systematic study of measuring and analyzing biological data for the purpose of validation or identification.
