Answer: The infamous Echelon spy network is a global satellite
system set up to monitor your every electronic move. Every telephone
call, fax or email you send is allegedly saved by Echelon is a spy
network which dramatically, illegally infringes on all of your rights
to privacy.
There is a wealth of information on Echelon all over the
web. Why not check out what the British BBC has to say about it,
otherwise see the other 12000 links courtesy of Google.
Fortunately Project SCIM software completely encrypts all of
your messages. Even if this spy network is monitoring you, it will
probably never be able to decypher your messages and peer into your
private life.
