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.

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 there still is a segment of consumers who think that > >when it is free, it's worthless) > > And a larger segment which will stick any CD they get in the mail into > their bootable drive.. LOL Didn't realize this.

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...
