The Homeland Security-funded project is Future Attribute Screening Technology, or FAST. Instead of focusing on whether you have hidden explosives or whether you’re carrying a weapon, sensors and cameras located at security checkpoints would measure the natural signals coming from your body — your heart rate, breathing, eye movement, body temperature and fidgeting.

Those physiological signs, measured together, will indicate whether you might have the desire or intent to do harm, project manager Robert Burns said…

Civil liberties groups maintain this screening technology is an invasion of privacy.

“Nobody has the right to look at my intimate bodily functions, my breathing, my perspiration rate, my heart rate, from afar,” said Joe Stanley of the ACLU.
