So, plausible deniability solution for disk wiping?:
Let, disk wiping tools LOAD the whole WIKIPEDIA in nxn matrices and
mix ALL the words & phrases in a random pool continuously and use THIS
as the "Wiping passes and patterns" while they wipe the disk-space
(instead of using random-pass or zero) and let the people who dont
need-to-know make sense of whatever they want to pull up from the
'patterns' generated from the ENCYCLOPEDIA OF KNOWLEDGE & unlimited
keywords and phrases and counter the same?
The problem is that although using Markov chains to generate pseudo-random
text, it's usually pretty obviously pseudo-random text. And in fact, they're
usually so random that it's pretty obvious it's just random words and
prove anything more or less than acres of zeros.
The problem is that every once in a while, those things actually generate
short chunks of intelligible text (especially when using a longer chain
length). So now, instead of being able to say to the district attorney
"The disk was full of zeros, and you can't prove what was on it before".
you're now saying to him:
"What do you mean, you found the phrase 'Drop the cocaine and kiddie porn
at my place around 9PM' on block 239349 of my hard drive?"
Generally a bad idea.
