Which identifies users by their vascular patterns?

• A. Iris Recognition
• B. Vein Matching
• C. Heart Rhythm Authentication
• D. Sniff Test

Answer: (B)

Vascular pattern recognition uses the unique network of veins beneath the skin to identify a person. This method, known as vein matching, typically uses near-infrared imaging of the hand or finger to reveal an internal vein map that is highly distinctive and stable over time. Because these veins are internal and difficult to replicate, this biometric is resistant to spoofing and provides a reliable way to verify identity. The other choices refer to different biometrics: iris recognition analyzes the iris pattern around the pupil; heart rhythm authentication uses individual heartbeat signals; and a sniff test is not a recognized biometric method. In short, identifying users by vascular patterns is achieved through vein matching.
