Which biometric authentication method verifies an individual's identity by capturing and analyzing the unique pattern of blood vessels in the retina located at the back of the eye?
Palm-vein scanning
Fingerprint scanning
Retina scanning
Iris scanning
Retina scanning works by illuminating the retina with low-intensity infrared light and recording the distinctive pattern of blood vessels. Because each person's retinal vasculature is highly complex and essentially unique, it provides one of the most accurate biometric identifiers. Iris scanning examines the colored ring surrounding the pupil, fingerprint scanning analyzes ridge patterns on fingertips, and palm-vein scanning maps veins in the palm-not the retina.
