There is active research addressing this problem, for example https://www.usenix.org/system/files/usenixsecurity25-park.pd...

But yeah, difficult too :)

I agree with "I'm fairly certain this will defeat 99.9% of malicious users".

Also, note that C2PA should have something like Level 3 as well: "The image is mathematically proven to have come from the physical camera sensor."

It's somehow difficult to achieve this, but it's possible (although the attacks will always be possible of course).
