I think that's not the problem that this technology is intended to solve.
It's not a "Is this picture copied from someone else?" technology. It's a "Did a human take this picture, and did anyone modify it?" technology.
Eg: Photographer Bob takes a picture of Famous Fiona driving her camaro and posts it online with this metadata. Attacker Andy uses photo editing tools to make it look like Fiona just ran over a child. Maybe his skills are so good that the edits are undetectable.
Andy has two choices: Strip the metadata, or keep it.
If Andy keeps the metadata, anyone looking at his image can see that it was originally taken by Bob, and that Fiona never ran over a child.
If Andy strips the metadata (and if this technology is widely accessible and accepted by social media, news sites, and everyday people) then anyone looking at the image can say "You can't prove this image was actually taken. Without further evidence I must assume that it's faked".
I think spinning this as a tool to fight AI is just clickbait because AI is hot in the news. It's about provenance and limiting misinformation.
Which does not solve that at all
Because the vast majority of "paparazzi" and controversy pictures aren't taken by Jake Gyllenhal. They are taken by randos on the street with phones who when sell their picture to TMZ or whatever.
And they aren't going to be paying for an expensive leica camera. And samsung and apple aren't going to be licensing that tech.
