Which biometric authentication method verifies a person's identity by capturing and analyzing the unique pattern of blood vessels located in the retina at the back of the eye?
Retina scanning
Facial recognition
Iris recognition
Fingerprint scanning
Retina scanning works by shining low-power infrared light into the eye and recording the pattern of retinal blood vessels, which are unique to each individual. Because these vascular patterns are internal and stable over time, retina scans provide a highly accurate form of biometric identification. In contrast, iris recognition analyzes the colored iris, fingerprint scanning examines ridge patterns on fingertips, and facial recognition maps overall facial features.
