How can a private torrent tracker identify which user is downloading a torrent file?

if you want to be anon on downloads/uploads, you.need to run through proxy servers and surf anonymously. as far as getting credit for it i don't think anything but word of mouth is what you need. actions like this will not make you money only bring trouble, ask piratebay or wikileaks. p.s. even though your computer may not record history or cookies your isp does.

I want to know how a private torrent tracker is able to associate a torrent file being downloaded with the user that downloaded it. I need to know this since I want to keep my files being seeded in a different computer and I need to make sure this upload traffic gets credited to my account. Thanks!
Just in case you didn't understand me well, I don't intend to cheat, I merely want to be able to download my torrents remotely, while still getting my upload credits.

If they told you how, then people would cheat.

Hi,
It's normally done via some kind of passkey system, within the tracker URL there will be a unique key which is associated with your account. for example http://tracker.com/announce.php?passkey=123456 -- "123456" is your unique ID and should seed torrent using a tracking url such as that with your passkey in.
