There's new technology that could help police spot terrorists in crowded places, but it might also pick up on you if you're having a bad day. It detects stress by looking at levels of blood oxygenation.

It was developed by Chen Tong, an associate professor of electronic information engineering in China. He hopes the technology will help police spot potential terrorists because they're likely to be very stressed before an attack.

The technology is still new, but Tong says it could eventually show officers stress meters over the head of every person in the crowd. Really stressed people would be marked by red faces.

Laboratory tests of the technology had yielded encouraging results, he said. But getting the device to work in the field presented new engineering challenges. The biggest obstacle was acquiring the remote data.

China has had problems with extremists attacking people with knives at train stations, so it's easy to see why it sounds like a good solution. It could also be used at big events like the Boston Marathon to pick up on terrorists before they have the chance to attack.

But, the tool also brings up some serious privacy concerns. It could flag innocent people as terrorists if they're having a stressful day. Chinese activists are also worried that it could be used by the government to silence protesters.
