Researchers helped provide a rare glimpse into how the great Chinese firewall really works

According to researchers from the University of New Mexico and University of California, Davis, the firewall used by the Chinese government to censor Internet material is not really as secure as the government wants users to believe.  Researchers discovered that much objectionable content could still be viewed, especially if online traffic was high.

Instead of simply blocking all web sites that feature content on a banned subjects, the Chinese government chooses to use a large dragnet that looks for the use of banned words.  If the Chinese system detects any banned words, reset commands are sent to the source and destination of the banned word.  Researchers found that the "'resets' effectively break the connection" so results will not be returned.

This different type of filter ultimately encourages a certain level of self-censorship - since Chinese users know that selected words are taboo, the users may choose to avoid the topics altogether.

"Imagine you want to remove the history of the Wounded Knee massacre from the Library of Congress," said Jed Crandall, University of California, Davis assistant professor of computer science.  "You could remove 'Bury My Heart at Wounded Knee' and a few other selected books, or you could remove every book in the entire library that contains the word 'massacre.'"

Both universities who took part in the study are now collaborating to work on ConceptDoppler, a tool that is able to give researchers a report if censorship in China changes.

Internet censorship in China runs rampant, with a number of popular web sites not available to traditional Internet users.  The Flickr photo sharing web site successfully loads, but users are greeted with a screen without images.  Several different popular online blogging services also cannot be used by Chinese users.    

The Great Firewall of China web site allows users to test if a specific URL is blocked by the Chinese firewall.

Freedom of speech

If socialism and communism are such great steps forward for all of mankind and the inevitable end result of the workers revolution, why do they not let the people speak? Why do they stifle communication?

Would not the average John Doe of China be the best example of the equality and liberty that one hundred years of socialism and communism have worked so hard to produce?

Or could it be that all that one hundred years of communism has produced is a body count that defies reason. That people really don’t want to live under the thumb of an oppressive government that views them as nothing more than chattel to be used and disposed of at the will and whim of the ruling class.

How many people did the Maoist revolution kill? How many were killed during the Cultural revolution? How many were killed in Tiananmen Square?

And the Communist Party runs China. There are no opposition parties. Not because they are so happy and filled with the fulfilled joy of socialism. No because the government will not allow it. I don't know what you would call it but I call a government like that a doctorial regime.

Swedes, Swiss, Canadians and all of the rest of the neo-socialist democracies are fully free to change their governments and to travel, assemble and speak as they wish. Not the Chinese.

The status of China in the world today. Easy. The most dangerous regime in Asia. With over a billion oppressed citizens. Devoid of even the most basic human rights. No free speech, no free assembly, no right to self determination. Need I go on?

Just to be clear socialism != communism. One is a form of government and the other is a economic system. In the US we often mistakenly use the two interchangably, but they are not the same thing.

China is not exactly Marxist communist country, but neither was the USSR. For that matter the US isn't exactly a Jeffersonian democracy.

In most western countries we talk about capitalism and socialism, but in every case its actually some blend in between the two.

One of my favorite quotes from JFK is that "Democracy may not be perfect, but we've never had to build a wall to keep our people in." He was talking about the Berlin wall in Germany, but I'd say it applies to China's firewall just as well.
