Understanding Face Liveness Detection Technology
Principles of Liveness Detection
Liveness detection is a critical aspect of biometric systems that ensures the authenticity of a detected face. By verifying that the face belongs to a live person and not a spoofed image or video, liveness detection helps prevent unauthorized access. This technology relies on various physiological and behavioral characteristics exhibited by live individuals. For example, eye blinking, head movement, or even changes in skin texture can be used as indicators of liveness. By analyzing these characteristics, anti-spoofing techniques can accurately determine whether the presented face is from a real person or an imposter.
Anti-Spoofing Techniques in Biometrics
Biometric systems employ several anti-spoofing techniques to enhance their security against spoofing attacks. These techniques aim to detect and differentiate between genuine faces and fake ones.
