There’s actually a web standard to authenticate images.
Several cameras on the market implement it, and even openai authenticates their images.
The limit of signing an image is that any modification will break authentication, but zero knowledge proofs can be used to “preserve authentication”. The current signatures & zkp have some practical limitations for large images, but nothing that won’t be fixed soon, if I had to guess.
