If a redacted document included a mixture of blacked- out and whited- out words and characters, then there would be fewer clues to the original text based on word length.

If we're allowed image- processing software, we can also randomly alter the lengths of redacted sequences so that, for example, there's no clue as to the total length of someone's name (as well as no clue, because of the striping, as to the relative length of given name and surname).

It is equally in the nature of random justice that the Rosenbergs were executed but Ted Hall was never prosecuted for selling nuclear secrets.

So crazy, it just might work! However, I'm sure if you put Coverdale, Camp X, and Bletchley on it, they'd find a way 'round it before breakfast.

Yes, it's amazing what some people will do to avoid making breakfast.
