The EU AI act doesn’t force C2PA or any particular standard. Yes many people will use C2PA erroneously, but C2PA is not meant for indicating content was virtually generated, but that it was not modified from origination.

C2PA is fallible if your origin is fallible. SynthID is a better standard for designating something was created with GenAI, though is limited in what it covers. For example, 3D content is currently a poor fit for both SynthID and C2PA. Audio is also imho poorly served.

There are a few things in the works for 3D…audio is an area I’ve tracked less.

Wacom have a synthid like embedding for geometric data https://youtu.be/AEi083BtgvU?si=Lu9EO4b1SPcfXiQU

And Apple just recently merged a authorship setup into USD https://github.com/PixarAnimationStudios/OpenUSD/pull/4188 (I didn’t realize it was merged till looking it up for this response)

But crucially , none of the global regulations require C2PA specifically. And with all synthetic data , you’re really relying on honor system for transparency.

It’s not like the sensor to display pipeline that C2PA and Apple’s Reference Image can provide when enforced in hardware.
