Which identification method relies on facial features?

• A. Fingerprint Authentication
• B. Hand Geometry
• C. Personal USB Key
• D. Face Recognition

Answer: (D)

Face recognition uses the unique features of a person’s face to identify or verify who they are. It analyzes facial geometry—distances and relationships between features like the eyes, nose, and mouth—and facial texture, then matches that data to stored templates to determine a match. This sets it apart from other methods: fingerprint authentication relies on fingerprint ridge patterns, hand geometry uses the overall shape and size of the hand, and a personal USB key is a possession factor, not a biometric trait. Because facial features can be distinct and are captured directly from the person, face recognition is the method that relies on facial characteristics.
