Don’t bring an AI detector to a deepfake fight: proving reality through multimodal provenance

Epistemic status: confident on the framing, speculative on the implementationTL;DR: Fake media detectors are on the losing end of an arms race. Instead of trying to spot fakes, we need to distrust images and videos by default, unless we can prove they're real. Cryptographically-signed multimodal capture raises the cost of spoofing exponentially, making casual fakes prohibitively expensive for the general public. Combined with platform policy and legal liability for untagged generated content, th...
