Naaa, this won't work.
Appending a single bit onto the end of the file makes a different hash.
So if you're scared of the thought police, just echo "crap" >>
whatever.mpg
and you no longer match the hashes. Even better "touch" the timestamp,
and
zip it up. The p2p software could even touch zip timestamps
automatically,
if they are older than (say) a 24 hours, or always... :-)
The only way to prove you're breaking copyright is to download at
least one frame and (fuzzy) pixel-compare that with every frame, in
every movie
you've got on record, a reasonable match is an copyright infringement.
Real tricky :-)

|Aloha, Ian.
|
|See: http://www.wipo.org
|
|The DMCA doesn't apply in the UK, but your government agreed
|to outlaw precisely the same activity using laws of local
|design. I don't know what the law is named in your country,
|but I bet if you look you'll find that it does exist. There
|was a deadline for passage of such legislation in order to
|comply with treaty.
|
|Your point is valid concerning the specific language of the
|threat letter your friend received, but that's little more
|than a typo.
|
|Sincerely,
|

|2 points about this thread.
|
|First, a lot of people have posted responses to the effect of
|"Unless xxx downloads the file that is supposedly breaching
|copyright, they can't tell if you *are* breaching copyright
|or not, thus breaching it themselves". Unfortunately this
|isn't true (at least for EDonkey). EDonkey creates a hash of
|the file on your hd, and compares it with the hashes on
|everyone elses hd. If you're in the middle of downloading the
|file, Edonkey can be sure it's resuming the same file from
|someone else (regardless of filename) by these hashes.
|Therefore to prove copyright infringment, all these companies
|need to do is to confirm your hashes are the same hashes as a
|"real" warezed version of whatever movie. Of course the movie
|house give the company legal permission to download etc the
|file, therefore they are not in contravention of copyright
|law. So all the company does is run a donkeybot or similar,
|scan the network and log all the people who are sharing a
|file with hashes that match a warezed ver of the movie. Until
|it becomes illegal to own a checksum of a file...
|
|As a side note, this hashing works against them too. They may
|have been flooding the p2p networks with "bad" versions of
|movies, but all any sensible person needs to do is to use a
|website (sharereactor.com, for
|example) and use the hash link off there. Providing the
|website is "true" (and there are enough of them), you'll
|always be garanteed to download the file you actually want.
|
|Secondly, companies & "entities" in the USA really need to
|get a damn grip of themselves. A friend of mine received an
|email from a company saying he was breaching the DCMA etc for
|exactly the same reason as Keith Tyler. The problem? He lives
|in the UK, just like me. Sorry to tell you, no matter how
|much you don't want to believe it (and how many times you put
|a Skylarov in
|jail) American law does NOT apply worldwide.
|
|All that said, piracy is of course a crime. Views are my own.
|Standard disclaimer applies etc etc.
