No pixelation, no blurring, no fuzzing, no swirling." "The bottom line is that when you need to redact text, use black bars covering the whole text. signNow offers a redact radio text function that helps improve document workflows, get agreements signed instantly, and operate seamlessly with PDFs. To perform the same task on a PDF is known as PDF Redaction. In simple words, whenever you see any part in any document which is blackened out to hide some information, it is known as Redaction. "Content creators and journalists should be aware of the additional risks when redacting information in videos and use a sufficiently high mosaic size/blur radius, or better yet, use an opaque, single-colored box," researcher Fabian Braunlein said.

This is far from the first time similar methods have been proposed to get back redacted information from pixelated content.
