As someone for whom
ordinary shopping is a high stress activity and regards a visit to the town
centre as no way to spend time, this article from China Daily, hat tip Schneier
on Security, is bad news.
Never mind being fair
skinned and getting red faced and hot when the sun is out.
Scientists
in China claim to have found a way to detect terrorists in crowds who may
be about to strike by the use of mini cameras and high tech analysis.
Quote:
Officers looking through the device at a crowd would see a mental
"stress bar" above each person's head, and the suspects highlighted
with a red face.
The researchers said they were able to use the technology to tell the
difference between high-blood oxygen levels produced by stress rather than just
physical exertion.
Unquote.
Schneier says "I'm not optimistic about this technology."
