In turn, the BBC turns a lens on the Chinese web-browsing experience, exploring one of the government's strongest methods of controlling the communication and information accessible to the public. 'China does not block content or web pages in this way. Instead the technology deployed by the Chinese government, called Golden Shield, scans data flowing across its section of the net for banned words or web addresses. There are five gateways which connect China to the internet and the filtering happens as data is passed through those ports. When the filtering system spots a banned term it sends instructions to the source server and destination PC to stop the flow of data.'"
