Amusing anecdote: There was a story about this issue on Slashdot one time, where someone possessing kiddy porn had obscured the faces by doing a swirl distortion, but investigators were able to sufficiently reverse this by doing an opposite swirl and so were able to identify the victims.
Then someone posted a comment to say that if you ever want to avoid this problem, you need to do something like a Gaussian blur, which deletes the information contained in that portion of the image.
Somebody replied to that comment and said, “Yeah. Or, you know, you could just not molest children.”
Pure black rectangles are not necessarily secure, either.

Brilliant.
Nice link. (It’s always good to read articles where ‘NLP’ doesn’t refer, approximately, to Jedi mind tricks.)
