Overview

• A new study shows that high-quality deepfakes can now include realistic heartbeat signals, undermining pulse-based detection methods.
• Deepfakes can inherit pulse patterns from original videos or have them intentionally embedded by creators, complicating detection efforts.
• Traditional remote photoplethysmography (rPPP) detectors, which estimate pulse rates, are no longer reliable against these advanced deepfakes.
• Researchers propose focusing on spatial blood-flow patterns across the face to identify physiological inconsistencies in synthetic videos.
• Cryptographic digital fingerprints are being explored as a sustainable approach to verify the authenticity of digital media.
