China's version of the NSA's Prism: Golden Shield

"China’s surveillance system is extremely wild, there are no rules governing it that are worth speaking of,” says
a Beijing lawyer named Xie Yanyi, who filed a public information request with the police to reveal how China’s own surveillance operations work. The New York Times reports that "he filed the request as a private citizen, said there were three programs in particular he wanted to know more about: Golden Shield, Great Wall and Green Dam."
