Which option is a biometric authentication method using facial features?

• A. Virtual Token
• B. Face Recognition
• C. Hand Geometry
• D. Personal USB Key

Answer: (B)

Biometric authentication relies on using unique physical characteristics to verify a person’s identity. When a method relies on facial features, it’s facial recognition, which captures a face image, analyzes distinguishing measurements and patterns, and matches them against stored templates. This is different from virtual tokens or USB keys, which are possession-based credentials, and from hand geometry, which uses the shape of the hand rather than the face. Facial recognition uses facial landmarks—like the spacing and shape of eyes, nose, mouth, and jawline—and applies algorithms to determine if there’s a match. It’s also worth noting factors such as lighting, pose, and potential spoofing protections that can affect accuracy.
