Airports Screen for Body Signals
Over the past several years, airport security has intensified due to the nation’s circumstances. The days of being able to walk through security checkpoints without being stripped of shoes and jackets are no longer present. However, they could potentially return if an experimental program funded by Homeland Security proves to be effective. The project is known as the Future Attribute Screening Technology.
The idea of the project is that sensors and cameras located at security points would measure natural signals coming from passenger’s body as they pass through. These signals include breathing, heart rate, eye movement, body temperature, and fidgeting. According to project manager, Robert Burns, the measurement of these signals combined is able to indicate one’s intent to do harm. He stated that there has been prior extensive research that suggests that one’s natural physical reactions are tied into mental and emotional state.
The machines being tested include an eye tracker, a thermal imaging device, a fidgeting monitor, and two machines that test heart rate and respiratory rates. Screeners will be keeping an eye out for elevated levels as well as lack of signals, which are both significant signs that there may be an issue that needs handling. Once there is cause for concern, security personnel will send those individuals for secondary screening.
There has been some criticism of the project, bringing up the issues of privacy and workability. Some critics have said that it is an invasion of privacy, and others believe it is impossible to carry this out effectively. The project manager has disputed this criticism and hopes to have the project ready for field testing in 2011.
This is a really fascinating technology, however, I just don't know how much it can be relied on for accuracy. Personally, I do quite a lot of fast breathing, fidgeting, and have an elevated body temperature when in an airport because I'm terrified of flying. It brings up some of the same arguments for and against polygraph machines - they can easily be tricked by a person who trains controlling their reactions and they can easily show false positives. I'm not sure that this tool will be effective enough to justify its market price.
