Comment on Why You Should Never Use Pixelation To Hide Sensitive Text
2910000@lemmy.world 1 day agoI wonder if hypothetically, AI could do the same with a box over text, even if it was 100% opaque. For example, if the data from the layer containing text was part of the image data passed to an image compression algorithm, and that data was somehow reflected in the output

If the image/video just has black pixels on the content, then there would be no information to extract and any attempt would just be filling things in.
When you talk about layers, you’re assuming that the creator left information behind in the Metadata, which wouldn’t require AI to extract.

By layers I mean image layers when manipulating an image in an image editor. So I guess what you’re saying is an image would be flattened before being passed to a compression algorithm?

Yeah, if I’m making something “masked/obscured” I should export it so that it’s in a raw format. That way there is no Metadata or information that could be leaked by accident.
Think of the Trump Epstein files, in those they kept them as pdfs so you could just unhighlight the redacted sections. If they had export it as a jpeg/png you wouldn’t be able to extract any information.
There are ways to remove the content from a pdf, but as we’ve seen, that leaves rooms for errors.
