How will they keep the private keys secret?

They can't, ultimately, it's basically just DRM but in reverse. I'm sure they can make it hard , with secure silicon etc., but they'll never make it impossible and that somewhat defeats the purpose.

It still serves a legal purpose, as long as it's difficult enough. If you need to physically modify the device to access the keys, then bringing the unmodified device to court should be enough to verify legitimacy of the signature.

Sorry for the dumb question, but what is stopping anyone from taking a picture of an AI generated image and passing it up as the "real deal"?

Depth of field etc will be hard to fake converting from analog back to digital like this esp if the focal length etc are encoded in the committed data

Since when are we taking photojournalists and social media users to court to verify each image?

It's not new, they just waited for the Patents[1,2] to run out. It's been a long time since I worked on it. [1] https://patentimages.storage.googleapis.com/f7/e9/46/00ddfea... [2] https://patentimages.storage.googleapis.com/4f/e3/ed/a46504f...

Many comments suggest this won't be useful technology in that it will be easily circumvented for nefarious purposes. Would you mind commenting on your perception of the potential of this particular implementation of the technology you helped create?

This is a way to sign an image while it's still in a camera. The signature is simply a way to strongly assert that an image is as the camera saw it in the raw.

I saw it as a way for Law Enforcement to prove an evidence photo was not doctored.

Generally, signing digital files is a great way to have some strong form of authenticity. There's a lot of unsigned content on the internet which makes impersonating people quite easy. We have fake news, fake comments, fake reviews, propaganda departments from intelligence agencies from hostile countries meddling with elections and public affairs, companies and lobby organizations spreading FUD, marketing companies s…

What if what was recorded or photographed, you don't want your identity associated with it due to its contents - e.g. whistleblowing classified government/state documents exposing horrific crimes against humanity? If no digital signature then it's automatically fake? It doesn't seem to matter at the moment though anyhow, the corrupt establishment so far seems to be a good enough job suppressing what they don't want o…

It’s identifying the camera, not the photographer. Of course there’s going to be metadata that could tie a camera to an owner, and some organizations may have checkin/checkout procedures that tie the camera to a specific person that is supposed to be in possession of it.

So… This camera owned by the New York Times, who only keeps track of the fact that an employee has a camera from the pool, not which camera in the pool. And if you’re not from some news organization, then I guess you’re in the burner camera category?

Meh would prefer untrusted digital world. Would act as a forcing function for us to live in the real world, where being there is the only reliable source.

Attesting documents is an old and important social technology. Here in the UK, the police have a long tradition of using pocket notebooks to record their observations and activities. It is a professional duty to make a contemporaneous note of anything significant that happens during a shift - attending a crime scene, observing a suspect, taking a statement from a witness. Each notebook has a unique serial number, whi…
