Black boxes and airline security

The news yesterday made me smile, the fuss over the release by the US Transportation Security Admin of some PDF documents, where they thought they'd blacked out all the secret bits of text.

Turned out that black boxes placed over text in a PDF document don't remove the text at all, it's still there and can be cut-and-pasted into a Word or Notepad file for reading.

PDF editing is quite unlike editing a bitmap (.bmp) file, where drawing a black rectangle will destroy everything underneath. PDFs are more like web pages than like bitmaps... much the same as Flickr offering fake security by having spaceball.gif spread out on top of the jpeg. Porn surfers know how to get around that!

Many of us on NBN have things to keep private and so I can sympathise with the TSA officials who made that cock-up. You think you've covered bases and then you have an 'oh, shit' moment.

Just for the fun of it, I'm going to try to update all five blogs tonight: xanga, newbudnudes, blogger/blogspot, celection and newbienudes.
