If you follow the links to read about the Shi Tao case from my previous posts, you will learn that Yahoo! provided the Chinese officials IP address information that linked to Shi Tao’s work place where he sent the email which was deemed “state secrets.” IP address is one of the powerful tools of internet censorship. A friend of mine said there are ways to get around this by using tools such as Torpark.

On the other hand, Google searches came up with different results depending on the country where you access their site or that country’s version of Google. One good experiment is a student worksheet from the lesson plan accompanying the PBS Frontline special, The Tank Man.

One of the most extensive research on China’s internet censorship was completed by Jonathan Zittrain and Benjamin Edelman, Berkman Center for Internet & Society of Harvard Law School. Their report is titled, “Empirical Analysis of Internet Filtering in China.”
