Chinese Panopticon on the Internet

12 09 2007

  The “Great Firewall of China,” used by the government of the People’s Republic of China to block users from reaching content it finds objectionable, is actually a “panopticon” that encourages self-censorship through the perception that users are being watched, rather than a true firewall, according to researchers at UC Davis and the University of New Mexico.

Researchers at UC Davis have announced that they will be presenting a tool that they have been developing at a conference at the Association for Computing Machinery Computer and Communications Security Conference in Alexandria, Va., Oct. 29-Nov. 2, 2007.. Code named ConceptDoppler: it acts as a sort of weather report on changes in Internet censorship in China, by using mathematical techniques to cluster words by meaning and identify keywords that are likely to be blacklisted.

This is extremely interesting and seems to have built on work done previously by researchers at Cambridge University. In addition, the researchers claim to have found new banned keywords. Most significantly, according to UC Davis researchers, the chinese firewall is changing. While the overall mechanisms are the same, the operators appear to have fixed the weakness which allows the firewall to be turned into a denial of service attack. Whilst this has yet to be confirmed, initial tests seem to be consistent with the UC Davis researchers’ claims.
