Besides the possibility of extracting the private key from the camera, doesn't this still leave the analog hole wide open? One could set up a high-DPI screen or similar in front of the lens, displaying anything they want, and have it captured with a genuine signature. This effort seems much more noble than DRM schemes, but ultimately it's the same fight against reality.

- duskwuff 1y agoIt's worse than you think: there are official C2PA mobile apps which will apply C2PA tags to anything captured by a "camera". This includes external USB cameras, such as HDMI capture cards. You can probably see where this is going.
- burnto 1y agoGood comparison with DRM. Perhaps it’s fairer to frame C2PA as an authenticity factor alongside other factors like a creator identity or publication credibility?
