Presentation Attack Detection (PAD)
PAD refers to techniques used to detect artefacts (masks, photos, deepfakes) intended to spoof biometric systems.
Frequently Asked Questions
What is Presentation Attack Detection (PAD)?
PAD refers to techniques used to detect and prevent spoofing attacks by verifying that a biometric sample originates from a live human rather than artificial artefacts.
Why is PAD critical for biometric systems?
PAD ensures security by preventing attackers from using masks, photos, or deepfake videos to spoof biometric authentication.
What methods are used for PAD?
Common methods include texture analysis, motion/liveness detection, infrared imaging for vein patterns, and challenge-response protocols.
