The use of the ocular region as a biometric trait has gained impetus, especially due to significant advancements made in iris recognition since 1993. The ocular region of the human face consists of the eyes and the surrounding structures such as facial skin, eyebrows, and nose bridge (Figure 4.1). While various components of the eye have been proposed as biometric indicators (viz., iris, retina, and conjunctival vasculature), it is the iris that has been extensively studied in the biometrics literature and used in large-scale biometric systems.
