How the Great Firewall Works

Presented at The Fifth HOPE (2004), July 9, 2004, 1 p.m. (60 minutes).

China currently puts in the most effort to censor information on the Internet. Bill was first involved in freenet-china and started DynaWeb in 2002. He has developed a thorough understanding of China's Internet censorship technology ranging from IP blocking to DNS hijacking etc. Various techniques have been implemented to get around them. There will be an explanation of a censorship algorithm never before publicly released as well as a live demo on how it works. Time permitting, an analysis of how the Chinese government uses information control on its people will also be presented.

Presenters:

• Bill Xia
  Bill Xia is president of Dynamic Internet Technology Inc., which helps Chinese web users get around the firewalls the authorities have erected to control access to information on the web.
