This is just C2PA for Claude-processed files, apparently. It's not related to their text watermarking.

C2PA is file metadata and can be trivially stripped away, unlike hidden watermarks, e.g. SynthID.

That is where their responsibility ends in terms of the EU AI Act. And that is fine and how it should be, no secret watermarks.

The way I read it, I thought they would just check if the file hash exists on their end. Is that not the case?

That’s incompatible with the file not leaving your browser, which you can trivially verify with the Network tab in chrome (or wireshack, etc).

This is just a C2PA metadata checker.

		Why? The browser can see the file and contents so it can calculate and send the hash over without the actual file ever leaving the browser.

That would invalidate the hash on minor changes. Too much effort and not enough return.
