Why are all the “linked from” URLs the same?

Why do so many IP addresses begin with 155.135?

Who can get access to this information?

But, what did Eric Snowden reveal?

Or a job with the NSA or an NSA contractor

Anonymity

Proxy server

Through a proxy

Normal connection

Proxy server

Glasnost which undermined the USSR and other socialist countries consisted in handing over the mass media, one by one, to the enemies of socialism.Raúl CastroOctober, 1997

One telex can cost twelve dollars [whereas] the same message costs 75 cents in the form of a fax and 3 cents via the Internet ... in spite of our blockaded circumstances, we are in a relatively good position [to face the challenges of such scientific and technological changes], due to the educational and scientific work developed by the revolution.Carlos LageOctober, 1997

The dictator’s dilemma

Ten year prison sentences

Summary

Self-study questions

1. Criminals use proxy servers to hide their activity. Should we make it a crime to operate a proxy server or are there times when anonymity is desirable?

2. Do you mind servers like the one at SurveyGizmo.com gathering data on you?

3. Can you think of reasons you might want data to be gathered on you?4. How do questions of privacy differ between cultures and political systems?5. What is the IP address of your computer? (You will probably have to get

some help answering that question).6. Proxy servers allow user anonymity if surveillance is a problem, but they

also enable a form of privacy – explain the way the latter works.
