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.

The private keys in credit cards (the ones with chips) are pretty secure. I'm no aware of them being extractable.
I also expect it not to be the low-hanging fruit of these cameras, but it is still one possible attack vector.

#24Slightly off topic, but has anyone felt they've improved at identifying "AI" images? My instagram feed is increasingly filled with "AI models", for some reason I can really easily identify these images whereas earlier on I really struggled a lot. Now I can more easily recogize these images, it actually turns me off using Instagram as I find it annoying / jarring. A few months back, I'd be looking at the hands etc to…

The idea is that full edit history is preserved - not verbatim in the metadata, but as a tag that can be looked up in a database. More info here: https://c2pa.org/
As much as I can glean from the video, it's heavily dependent on a central database to hold the edits. If someone alters a video, the original would need to be viewable. Who's storing that, and streaming it? And then who's paying for that? I'm guessing that in the end this will be a paid service for journalistic organizations who buy in.
What exactly do you mean by "need"? This system doesn't stop anyone from distributing edited or staged or otherwise bogus media, because that was never the intention. It does allow someone to demonstrate - with a fairly high level of trustworthiness - that the media they're delivering is raw, unedited footage taken with a particular camera at a particular time in a particular place.

I _think_ I'm good at identifying AI images, but part of it is you can never be sure.
But in some sense , when could any photo be trusted ? We’ve had airbrushing, CGI forever now.

With homomorphic encryption you can make them provably unextractable.
PUFs attempt to prevent this, but I'm not sure it's been done in a provably secure way yet https://en.wikipedia.org/wiki/Physical_unclonable_function

A GPU shortage under popularity growth should result in more obvious AI art over time sans an algorithm breakthrough that reduces compute cost by orders.
