It might be resistant to screenshots - unless I missed it, the article didn't clarify whether the obfuscation process is applied to the image on a per-pixel basis, or within the file format itself...
If it was that easy to bypass it would be a pretty futile mechanism IMO, one would just need to convert the image to strip out the obfuscation 🫠 or just take a screenshot as you said
Sounds like it's tiny changes to the image data to trick it. But it also sounds dependent on each algorithm. So while you might trick Stable Diffusion, another like Midjourney would be unaffected.
And either way, I'd bet mere jpeg compression would be enough to destroy your tiny changes.
These things never work in the real world. We’ve seen this over and over. It’s snakeoil. Latent space mapping may survive compression but don’t work across encoders.
