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
An internet protocol called C2PA adds a “nutrition label” to images, video, and audio. — The White House wants big AI companies … Mastodon: @timbray@cosocial.ca , @esnyder@mastodon.social , and @timbray@cosocial.ca . Twitter: @techreview . Forums: Beehaw Mastodon: Tim Bray / @timbray@cosocial.ca : @esnyder @Techmeme — 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 Emile Snyder / @esnyder@mastodon.social : @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..) … Tim Bray / @timbray@cosocial.ca : @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. Twitter: @techreview : The White House wants big AI companies to disclose when content has been created using artificial intelligence, but identifying AI-generated material is a massive technical challenge.
