China announces plan to label all AI-generated content with watermarks and metadata.
(english.news.cn)
This is a most excellent place for technology news and articles.
That's a different thing. C2PA is proving a photo is came from a real camera, with all the editing trails. All in a cryptographic manner. This in the topic is trying to prove what not real is not real, by self claiming. You can add the watermark, remove it, add another watermark of another AI, or whatever you want. You can just forge it outright because I didn't see cryptographic proof like a digital sign is required.
Btw, the C2PA data can be stripped if you know how, just like any watermarks and digital signatures.
Stripping C2PA simply removes the reliability part, which is fine if you don't need it. It is something that is effective when present and not when it isn't.
It's never effective. At best, you could make the argument that a certain person lacks the wherewithal to have manipulated a signature, or gotten someone else to do it. One has to hope that the marketing BS does not convince courts to assign undue weight to forged evidence.
