Which type of scan measures a person's external features through a digital video camera?
Options
- AIris scan
- BRetinal scan
- CFacial recognition scan
- DSignature kinetics scan
Explanation
Facial recognition is the biometric method that uses a digital video camera to capture and analyze a person's external facial features for identification.
Common mistakes.
- A. Iris scans analyze the unique colored ring surrounding the pupil of the eye using near-infrared light, not a standard digital video camera capturing external features.
- B. Retinal scans use a low-energy infrared beam to map the unique blood vessel patterns on the back of the eye, which is an internal feature not visible to a video camera.
- D. Signature kinetics (dynamic signature recognition) analyzes behavioral characteristics such as pen pressure, speed, and stroke order during signing, not physical features captured by a video camera.
