how facial comparison algorithms detect AI

Deepfakes aren't just a social problem or a "creepy" use of generative AI; they represent a sophisticated adversarial attack on human visual perception. For developers working in computer vision, biometrics, and digital forensics, the news of $200 million lost to deepfake scams in early 2025 is a massive signal. It tells us that our "gestalt" visual processing—the way the human brain identifies a face—is now a deprecated security model.

The technical implication for those of us building investigation tools is clear: we have to move the goalposts from visual "realism" to mathematical "verification."
