Marking for Redaction

    So here’s something we just discovered.

    We received a set of drawings under NDA which had the name of the company blacked out.
    However, whoever did this ‘redacted’ them incorrectly. It appears that they used a highlighter tool to do the redactions, made it black, and then did an unrecoverable flatten.
    (I assumed this because the ‘redactions’ have that small radiused end on them that text highlights have)

    One of my team ran the drawings through ChatGPT and it was able to read under the black highlights. It also spat out exactly who we thought this place was.

    So then I had him run a proper Redaction and ChatGPT could not read what was underneath.

    Moral of the story, if you’re going to mark a drawing for redaction, do it properly. Revu has those tools built in. Don’t just use a black markup and flatten it, the AI can still read what’s underneath.

    Oh, and if you really don’t want them to see if its been redacted, change the colour of the redaction to white. 😁

    This is a great share. Thanks @Doug McLean

    the redaction tool is built to completely remove the data not just cover it up. This was a cool way to test it!

    Thank you for sharing this @Doug McLean

    While we don’t have a use for this in our day to day operations it’s always good to know what tools are out there!

    Who knows, might even be a Bluebeam Jeopardy response some day… 🙂
