Which identification method uses unique fingerprint patterns for verification?

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

Answer: (C)

Fingerprint authentication uses the unique patterns of ridges and minutiae in a fingerprint to verify identity by comparing the presented print with a stored template. During enrollment, a fingerprint is captured and features are extracted to create a reference template. For verification, the user presents a finger; the system extracts features from the live print and computes a similarity score against the stored template. If the score meets the threshold, access is granted. This one-to-one comparison leverages the distinct and relatively permanent nature of fingerprint patterns, making it the method best described as using unique fingerprint patterns for verification. Face recognition relies on facial features, not fingerprints. Hand geometry uses the overall shape and measurements of the hand, which are less unique. A personal USB key is a hardware token, not biometric data.
