Even if you map a particular hash into one of a million known-benign values, which takes work, there are multiple orthagonal hash algorithms included on the NIST CD. (Eg good luck finding values that collide in MD5 & SHA-1 & SHA-256 simultaneously!)
Argh. You misunderstood me. I don't want to find hash collisions, to create a false known hash - that is just too difficult. I want to make every file in the machine recognized as "unidentifiable".
These hash-CDROMs are also useful for finding unlicensed software and music....
Another reason for making your data unique.
In that case, yes, although ultimately the RIAA could hire offshore Indians to listen to your stego'd/uniquified Madonna song and identify it. (Of course, they don't know if you own the vinyl for it... and software can be sold by the original purchaser, too, right?)
The adversary has acoustic fingerprinting software. Even cheaper than the Indians. The signature busting of MP3s has a disadvantage, though: makes their sharing back to the P2P pool more difficult, and a lot of programs relying on their hash (emule, Kazaa(?),...) instead of their file name will consider them a different file, which causes problems with multisource download (though the problem won't be on your side).
Yes something like a Tomlinson (_Big Breach_) sleight of hand with a Psion card is a good idea, as is the microwave oven trash can next to your machine :-)
Or a small propane torch or a lighter (the kind that makes the hissing blue high-temperature flame), or even a sticker with magnesium shavings to burn through the chip when lit.

And a larger segment which will stick any CD they get in the mail into their bootable drive.. LOL
Didn't realize this. Seems I still overestimate Them the People.
Sorta like the National Forests... resource of many uses... may as well include a mixmaster payload in that worm :-) which also provides some other overt free benefit like antivirus or anti-helmetic or defrag or game or bayesian spamfilter or chat or screensaver or anon remailing client or free ringtone :-)
Free ringtones. Good attractant these days. I tend to forget about them as I tend to shun fancy tones - telephones should have a distinctive ring but "distinctive" does not have to mean "orchestral". But apparently there are large sets of people who like it. Weird...
