Mastering the redaction
BY Nancy Scola | Tuesday, December 15 2009
Kevin Drum worries that the recent flap over that TSA manual is going to spark an unfortunate Washington backlash against searchable PDFs. TSA employees attempted to redact the sensitive manual, it seems, by drawing black boxes over the private bits in Adobe Acrobat. Unfortunately, it can be pretty trivial to "unredact" anything that is blacked out with a box made only of pixels.
Not for nothing did an office I once toiled in actually print out documents and scratch things out with a Sharpie marker when we absolutely positively had to be sure that something couldn't leak out into the public. We'd then scan in those marked-up hard copies on our scanner/copier, and send around that digital file. No chance of anything slipping through that way, but that also means that those documents weren't natively searchable. That's no good, but there's a decent bit that some government offices are looking at that today as something preferable to the public humiliation TSA is going through right now.
Someone in Drum's comments suggests that Adobe -- which has, of course, been making a big push to be thought of as a player in the open government movement -- come up with a fool-proof "redaction" option built right into Acrobat, which seems like a pretty good idea.
