New Scientist has an article looking at the US$312 million surveillance system installed for the 2004 Olympics in Athens. The eyes and ears consist of 1,000 high-res and infrared videocameras peppering the city. Cell and landline telephone calls are being recorded, converted into text, and "scanned for phrases that could be linked to terrorist activity." The software's developers say it speaks Greek, English, Arabic, Farsi, and other major languages.
(John Pike, an analyst with the defence think-tank Global Security) believes other undisclosed measures are undoubtedly in place, such as face recognition from video footage. He says such surveillance technology has already proven its worth in intelligence gathering. "They're basically the sort of stuff the National Security Agency has been using for some time," he told New Scientist. "And they seem to place great faith in it."
The human security is massive as well–there are seven security people for every athlete.
