You'd think the go-to workflow for releasing redacted PDFs would be to draw black rectangles and then rasterize to image-only PDFs :shrug:

Not to mention some PDF editors preserve previous edits in the PDF file itself, which people also seems unaware of. A bit more user friendly description of the feature without having to read the specification itself: https://developers.foxit.com/developer-hub/document/incremen...
This made me think of something I came across recently that’s almost the opposite problem of requiring PDFs to be searchable. A local government would publish PDFs where the text is clearly readable on screen, but the selectable text layer is intentionally scrambled, so copy/paste or search returns garbage. It's a very hostile thing to do, especially with public data!
With the aggressive push of LLMs and Generative AI ..i am expecting a lot of OCR features to become "smarter" by default, namely go beyond mechanical OCR and start inserting hallucinations and sematically/contextually "more correct" information in OCR output
It's not hard to imagine some powerful LLMs being able to undo some light redactions that are deducible based on context
As someone who's built an entire business on "anti-screenshots" this is brilliant.
PDF redaction fails are everywhere and it's usually because people don't understand that covering text with a black box doesn't actually remove the underlying data.
I see this constantly in compliance. People think they're protecting sensitive info but the original text is still there in the PDF structure.
