Three years of "is this real or AI?" Nobody can answer that.
Who signed it? That has an answer. Until now you could scrub it off.
In 2023 Xuandong Zhao proved you can wash any invisible watermark out with a diffusion model. Guillaume Meyer built the best public version of that attack watermarks-remover. So I stopped trying to survive the scrubber and instead built a trap.
Backfire is a fixed point of the attack. Run the scrubber. Congratulations, you've either notarized my mark or destroyed your own file.
Run it at me. Break it and your name goes in CREDITS.md.
provcheck 1.3.0 released today, Apache-2.0.
