In
class today, April 5, 2012, I will talk about internet censorship, specifically
the Great Firewall of China, the largest and most effective internet censorship
project to date. Officially known as the Golden Shield Project, development of
the Great Firewall of China started soon after internet came to China. Started
in the 1990s, the original idea was to have a comprehensive surveillance system
that included speech and facial recognition, video monitoring, etc. It seemed
like a mix of 1984 and V for Vendetta. However, this ultimate goal was never
reached. The internet expanded so fast, that it was hard enough for the Chinese
to keep up with the firewall, that they did not have the time or resources to
implement everything else. The project was officially done being installed and
integrated in 2008, but it is still updated almost every day.
The
Great Firewall uses four main techniques to keep people in China from accessing
censored material:
1.
IP Blocking
2.
TCP Connection Cut-Off
3.
URL Blocking
4.
Content Scanning
Together these methods work to make
sure that you cannot access anything that they have on their “blacklist”. The
thing is, things on the “blacklist” change everyday, depending on what’s going
on in the world. For instance, some news sites may be available most of the
time, but if one day they have an article about riots in Tibet, the site will
be blocked that day, and become available again when the article goes away.
This project has signifiganctly impacted
the effect of the internet in China. Everyone and everything from your common
citizen to mega companies like Google have to deal with it. The system is so
effective and high tech, that China has made a business out of exporting its
technologies. The Great Firewall of China has taken internet censorship to the
ultimate extreme.

Who controls the network? In China, the answer is quite clearly the government. Using the sophisticated network of technical and legal measures known as the Great Firewall of China, the Chinese government can censor the entire population’s internet access. While China is the most extreme case, they are not the only nation that censors the internet. It is clear to see, that almost any government could at any point in time, enact a similar system. So, if you think about it, no matter what system is currently in place, the government controls the network, because they can take over control of it, whenever they so choose.
If you want to know more about what it is like behind the Great Firewall of China, you can check out http://greatfirewallofchina.org/ to see which sites are blocked, or install the China Channel Firefox add on from http://download.cnet.com/China-Channel-Firefox-add-on/3000-11745_4-10900445.html, which will let you browse the internet, like you’re on a computer in China.
