IP address Stop and find your IP address
Geo-location Stop and find your location. From ip2location.com
Who are you? IP address + time and date + ISP log → Internet account holder Who can get access to this information?

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 Castro October, 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.

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.
