According to ZDNet (which cites the Wall Street Journal) a report by Harvard University researcher Isaac Mao, who has seen the code, says there are two kinds of keyword documents in the software: one is related to pornographic content, and the other related to political content. Not only that but the documents related to political stuff are much, much bigger than those related to pornographic content.

Speculation that the software did more than the government were letting on has been mounting since China first announced the decision earlier this week and computer experts believe that with Green Dam installed on every computer, the Chinese government will gain access to personal information and have the ability to monitor Internet use through the software.
