Which biometric method analyzes facial features for identity verification?

• A. Facial recognition
• B. Retina scanning
• C. Hand geometry
• D. Finger printing

Answer: (A)

Identity verification through facial features relies on facial recognition. This method analyzes the geometry and texture of a person’s face—such as the positions and proportions of the eyes, nose, and mouth and the overall facial contour—and compares what the camera captures with stored templates to confirm identity. The other biometric options measure different traits: retina scanning looks at the unique patterns of blood vessels in the eye, hand geometry compares the size and shape of the hand, and fingerprinting analyzes the ridge patterns on fingertips. Because it specifically targets facial features for verification, facial recognition is the correct choice.
