Re: Method of detecting intermediary communication device. US Patent 7,466,654

If I'm reading that abstract right, yes; however, it's a moot point. Tor
- - historically* - doesn't try to hide from either a local observer
(let's call her "Eve") or a destination server (let's call its admin
"Bob") that a user (let's call her Alice) is using Tor (i.e., an
"intermediary communication device").

It simply prevents:
- --Eve from knowing that Alice is talking to Bob;
- --Bob from knowing that Alice is the one talking to him.

Eve can easily figure out that Alice is using Tor (but not who she's
talking to). Bob could look up the IP of the exit node Alice is using to
connecto to his server, and realize that a Tor user is contacting him,
but not that it's Alice.


*: Although I'm not well-versed on it, the new "bridges" model -
intended primarily for citizens of oppressive regimes - is supposed to
help prevent Eve from knowing Alice is using Tor; it does not, however,
prevent Bob from knowing a Tor user is connecting to his server.
