Re: TSA redaction fail: hidden text easily readable via copy & paste
#12This isn't the first time this has happened. Several years back, another government agency made the same mistake. On a slow computer, the text would render first, and could be seen for several seconds before the black boxes would appear. Googling around, it seems to be a fairly common mistake, going back to at least 2000. http://www.securityfocus.com/news/7272 http://cryptome.org/iran-cia/cia-iran-pdf.htm http://blog…
(I encouraged them to go further and switch to PDF format for the distribution, but they wouldn't.)

#13It's helpful to understand a little bit of how a PDF file works. A PDF file stores a sequence of instructions for what do draw on a page. The instructions are commands, such as "write this text here" or "draw a circle there." When you draw black redaction boxes, you are just appending an instruction to the end of the list ("draw a box here"), but most of the time the previous instructions are all still there. Really,…
It is however trivial for even a non-technically inclined person to remove the text content through Acrobat's content editing pane.
Just as you suggest, things like this seem to be an example of someone in a large organization not quite understanding how the "magic" behind the tools they use work and winding up with results they didn't expect.

That's such an obvious list I'm not sure if it's from the document itself, or if you just wrote down what it would probably be.

I was a little surprised about Cuba. They're not our favorite government, but I don't see them as a security risk.
