A look at C2PA, a standard that relies on cryptography to encode provenance information of media content, started by Adobe, Arm, Intel, Microsoft, and Truepic (Tate Ryan-Mosley/MIT Technology Review)

@Techmeme See

I've been yelling for a couple years now that C2PA is a big freaking deal and also the only plausible defense I've seen against the incoming tsunami of generative-AI-based disinformation.
In the not too distant future, any media object without C2PA provenance should be assumed a malicious deepfake.
@timbray @Techmeme am I right in assuming that the idea is that, in a C2PA world, cameras will be signing images? I can see a whole raft of sticky issues there.
(Privacy issues of making photos traceable to individual hardware, issues of attempting to keep key material on camera that owner of camera can't access, revocation of compromised signing keys, etc..)
Any links to serious discussions of them?
1. Obvs has to be opt-in. Not just cameras but also Photoshop and equivalents, and CMSes.
2. Like any security measure, imperfect, all you can ever do is drive up the cost of bad action. Worth doing.
3. Lots of public discussion out there although it's annoyingly gone a bit off the radar this year
