China has released a set of guidelines on labeling internet content that is generated or composed by artificial intelligence (AI) technology, which are set to take effect on Sept. 1.

Would it be more effective to have something where cameras digitally sign the photos? Then, it also makes photos more attributable, which sounds like China’s thing.
This is the one area where blockchain could have been useful instead of greater-fool money schemes. A system where people can verify provenance of images or videos pertaining to matters of importance such as news stories. All reputable journalism already attributes their photos anyways. Cryptographic signing is just taking it to a logical conclusion. But of course the scary word ‘china’ is involved here therefore we must only contrarian post.
No, I don’t want my photos digitally signed and tracked, and I’m sure no whistleblower wants that either.
Of course not. Why would they? I don’t want that either. But we are considering the actions of an authoritarian system.
Individual privacy isn’t relevant in such a country. However, it’s an interesting choice that they implement it this way.
Apart from the privacy issues, I guess the challenge would be how you preserve the signature through ordinary editing. You could embed the unedited, signed photo into the edited one, but you’d need new formats and it would make the files huge. Or maybe you could deposit the original to some public and unalterable storage using something like a blockchain, but it would bring large storage and processing requirements. Or you could have the editing software apply a digital signature to track the provenance of an edit, but then anyone could make a signed edit and it wouldn’t prove anything about the veracity of the photo’s content.
Hm, that’s true there’s no way to distinguish between editing software and photos that have been completely generated. It only helps if you want to preserve and modified photos. And of course, I’m making assumptions here that China doesn’t care very much about privacy.
That’s actually already a thing: https://www.theregister.com/2022/08/15/sony_launches_forgeryproof_incamera_digital/
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.
