So it seems like image generation/deepfake proliferation is pretty inevitable. I imagine we can't trust any image anymore (for e.g. identification verification purposes) unless it is done in person or otherwise notarized somehow. Is there a way (NFT-ish?) to "tag"/sign an image to say it was taken by an actual camera?

But how do you check that it was actually taken by a camera and not just tagged as such?

Secondly, even if you solve that, how do you know it's not a photograph of an AI-generated scene?

I think this is very obviously not the right approach.

		I theory you could install some kind of TPM-like device to every hardware that signs the data with key generated by manufacturer. Should be designed in such a way that it is very easy to break it when trying to tamper with it

		I guess both the camera and the image need keys. (But really I have no idea this stuff is out of my realm!)

I tried pushing this 5 years ago when at Apple but got nowhere. IMHO only the OEM’s can achieve this.
