So that all the RIAA has to do is provide a sample mp3 and then DropBox can see who has AES(F, H(F)) stored. Only the files with user generated unknown content can remain mysterious to DropBox, widely used files cannot. No, Dropbox does n

That's not true. As is, in a lot of crypto problems, there are powerful workarounds that require a lot of work. See here for one idea: http://news.ycombinator.com/item?id=2461713 Unfortunately, this starts to become a cat-and-mouse game.

The fact Mac OS X is a security pushover is pretty well known[2]. That raises the question then, why aren't we seeing more Mac viruses and malware? Is it purely a question of economics that market share answers? Is it because there's more

What if you price it in such a way that lending someone a copy allows them to still pay the creator? You do realize that you as a creator are taking advantage of the medium to distribute your creation in much more efficient ways, yet, you d

Wasn't it shut down by the F.B.I.? It be instructive to see if something similar can happen to a crypto-currency. Maybe it is not directly relevant, but still useful to keep around in the wiki.

Yes, that is an excellent point. Although, in a lot of cases, photocopying a book requires significant labor, with much lower guarantee of quality and I've rarely seen people making a business out of photocopying novels. For technical books

Is it just me, or has there been a flurry of internet-related legislation of late. With the PSN hack still fresh on their minds I wonder how much more legislation is yet to come. Between this, COICA and PROTECT IP, things are starting to lo

You're looking for two files f1 and f2 that hash to the same thing? And hoping that f1 is randomly generated by you, but f2 is someone else's original file which can be downloaded because of dedup? In general, solving for f1 and f2 (i.e., y

You can do (1) and (2) but it is not trivial to prove that it works. See: http://news.ycombinator.com/item?id=2461713

In theory, if multiple snapshots of truecrypt are maintained, I believe it must be secure, but did the designers of truecrypt keep that in mind? Does dropbox maintain periodic snapshots of uploaded files?

That's an excellent solution. A couple of points: 1. It is usually not a good idea to use your key as a function of the message. Here, you would require your hash function to have a good min-entropy given inputs from whatever distribution M
