- Generation technology: diffusion models + face-reenactment networks + voice cloning can produce undetectable fakes in real-time at near-zero cost - Biological signal detection: rPPG (remote photoplethysmography) detects blood flow patterns in facial pixels — current deepfakes don't model this accurately - C2PA (Coalition for Content Provenance): cryptographic signing at capture moment — Canon, Nikon, Adobe, Leica support; creates chain of custody from sensor to publication - Detection accuracy gap: lab conditions ~95%, social-media-compressed content ~70% — compression destroys detection artifacts - The asymmetry problem: a deepfake reaches 10M viewers in hours; corrections typically reach <5% of the original audience
