312-50V10 Question #282: Real Exam Question with Answer & Explanation

Question

Options

• AIris scan
• BRetinal scan
• CFacial recognition scan
• DSignature kinetics scan

Explanation

Facial recognition is the biometric method that captures and analyzes a person's external facial features using a digital video camera.

Common mistakes.

• A. An iris scan captures the unique patterns of the colored ring of the eye using near-infrared light at close range, not external facial features through a standard video camera.
• B. A retinal scan illuminates and maps the blood vessel patterns at the back of the eye using infrared light, requiring the subject to look into a specialized device.
• D. Signature kinetics (also called dynamic signature verification) measures behavioral biometrics such as pen pressure, speed, and stroke order during signing, not physical features captured by a camera.
