Recent releases of heavily redacted documents (including the Epstein files) raised a technical question for me:under what conditions, if any, could forensic techniques recover information from such shaded areas?. Thinking about it, I remember Interpol fighting to find a pedophile nicknamed Mr. Swirl, who published photos and videos proving his crimes. His face was under the influence of Swirl, which alters the pixel order in images. There are two types of effects: the first changes the pixels themselves, which is difficult to reverse, and the second changes the pixel order in images, which is relatively easy to do using appropriate algorithms. So, my question is: can we modify or discover an algorithm that would allow us to remove the shading in Epstein's files? Thank you.
