How do biometric security systems work beyond fingerprints?
Your heartbeat, vein pattern, and walking style can all identify you.
The answer
Modern biometric security goes far beyond fingerprints and facial recognition. Iris scanning maps over 200 unique features in the eye's colored ring with false-match rates below 1 in 1.2 million. Vein pattern recognition uses near-infrared light to map the unique pattern of blood vessels beneath your skin. Voice recognition analyzes over 100 vocal characteristics. Behavioral biometrics track how you type, walk (gait analysis), and even hold your phone. Some systems use cardiac signatures - your heartbeat's unique electrical pattern - which is nearly impossible to spoof.
