Here’s my new carry-on bag-you like??
Sounds a whole lot sexier than it really is but hey, you want to get there fast so listen up.
Think you know what its like to get “checked out”? They have Behavior Officers that are psy-cho-logically trained to tell if you are a weirdo, machines that sniff you, machines that strip you and puff air at you, CCTV that knows you on sight and much more. So get all dolled up before you head out and remember what your momma said about clean underwear!
U.S. Army perspiration detectors to sniff out the bad guys
Published 6 June 2009
Intelligent CCTVs already note weird or unusual behavior and alert security personnel to that fact; the U.S. Army, building on an earlier project which tried to identify unique body odors, wants perspiration detectors to help detect “harmful intent”
The software that controls intelligent CCTVs already contains algorithms which notice unusual or weird behavior — an individual standing on a train platform for more than a few minutes; people who wear heavy overcoats on a hot day, etc. — and alert security personnel to that fact. The U.S. military, too, wants to use behavioral irregularities as “indicators” of “possibly suspicious and harmful intent.”
Noah Shachtman and Katie Drummond write that the Army recently asked for proposals for a new suite of biometric sensors which will sniff out bad-minded people by examining their “expressions, gait, and pose” from afar. The “Image Analysis for Personnel Intent” project is also supposed to spot would-be evil-doers through their “abnormal perspiration and changes in body temperature.”
This is not a new idea. The researchers at DARPA spent millions of dollars on the Unique Signature Detection Project (formerly known as the Odortype Detection program), a project aiming to look for unique “odortypes” (see Shachtman’s discussion of the project).
In 2002 a team of Minnesota scientists used thermal changes around the eyes to spot deceit on a test of twenty new military recruits. The researchers claimed that their system nabbed the liars about 80 percent of the time — the same as a standard polygraph test. The following year, Boeing patented a device that used hyperspectral scans to identify surges in body temperature prior to “a stress-induced blush.” Hyperspectral systems monitor wave lengths of electromagnetic radiation, which are emitted by living, breathing bodies, and can detect faint changes in heat that precede blushing or perspiration.
Shachtman notes that one cannot confirm malice using sweat detection alone. The military wants a “light, portable” sensor that combines this hyperspectral system with spatial surveillance, to spot threatening changes in expressions and body movement. While traditional biometrics measures — iris scans, fingerprint reads — have to be done up close, and on willing subjects, the Army wants to be able to zoom in on “individuals including those who are uncooperative in unconstrained indoor and outdoor situations at a distance of at least 45 meters from the target.”
The Army believes such a sensor could have widespread applications — “border patrol, stand-off interrogation, access control, surveillance, and target acquisition and airport security.”
The Army is also mindful of the commercial uses of such systems: “The system would initiate by attaining information about users intent rather than making it necessary for the user to initiate it manually (e.g. user focuses gaze on a switch, therefore initiating the switch to turn on a light).”
