Definition
Iris is the colored organ inside the eye. In the human eye, as illustrated in Fig. 1, the iris is a thin diaphragm that lies behind the cornea and anterior chamber. The muscles of the iris expand and contract the aperture of the iris (also known as pupil) to adjust the amount of light which passes through the lens [14]. In the information technology field, automated pattern recognition of the human iris can be used to identify each person for security purposes and access control (Fig. 1).
