From Financial Times:
China’s government is stepping up internet scrutiny by equipping its web censors with more advanced software that allows them to spot risks of subversion much earlier and root it out more efficiently, according to the country’s internet security market leader.
The revelation from Beijing TRS Information Technology, China’s leading provider of search technology and text mining solutions, that it is thriving on the government’s desire to better “manage” public opinion, comes as the political leadership is facing growing challenges, mostly voiced through the internet.
Currently, the security forces are cracking down on intellectuals associated with Charter 08, an appeal for democracy and human rights that many see as the most significant such document since 1989 and which has, defying Beijing’s net censorship, been collecting signatories over the web.
Traditionally, so-called internet cops look for subversive content via keyword searches on Google or Baidu, He Zhaohui, marketing manager at TRS, told the FT.
