With a central authority to issue unique "authentic camera keys"? What dystopian nonsense you're suggesting!
Because without such an authority, what's to stop the deepfake source from generating its own unique key? And we're back to square one.

- dmurray 5y agoYou don't need a centralized authority. Every manufacturer can issue their own keys. I take a digitally signed photo and tell you "I took the photo with this tamper proof Canon camera, and I can prove it by taking more photos of any subject you ask for and signing them with the same key". If you worry that I made an authentic-looking counterfeit Canon camera (but you're satisfied I couldn't have extracted the private key from a real one), Canon can confirm that they sold a camera with that key.

Surely there will be enough cheap devices out there that not everyone can be expected to remember the names of venerable manufacturers? I personally have no idea who makes the camera in my phone. Anyway, the point is moot. The analog hole is still there, you'll just feed the pixels straight from the deep fake generator into the Really Real Tamper Proof Canon's CCD.
