...stress that creates the clues picked up by polygraphs also boosts blood flow in capillaries around the eye. A new application of thermal-imaging technology, called periorbital thermography, uses a high-resolution camera to detect temperature changes as small as .045°F (.025°C). Endocrinologist James Levine of the Mayo Clinic in Rochester, Minn., co-authored a paper in the journal Nature in 2002 in which he claimed a lie-detection accuracy of 73%. Investigators at the Department of Defense Polygraph Institute (DODPI) in Fort Jackson, S.C., tell TIME they have reached...
...agree that the face tells tales we may wish it didn't. San Francisco psychologist Paul Ekman has codified 46 facial movements into more than 10,000 microexpressions in what he calls the Facial Action Coding System (FACS). He and Frank, who helped devise the catalog, say they can detect deception with 76% accuracy. According to Ekman, thousands of people have been trained in FACS, including Transportation Security Administration personnel. While similar behavioral screening has been used in British airports for several years, FACS is only now being rolled out as a terrorist-screening tool in a dozen U.S. airports...
...biggest problems, however, may be ethical and constitutional. For now, improved lie detection is likely to have broad public support. But what about when it reaches more surreptitiously into our lives? Biophysicist Britton Chance of the University of Pennsylvania has explored ways to use infrared light projected from a distance to penetrate the skull, looking for signs of stress similar to the ones fMRIs detect. Both that and remote periorbital thermography could be used undetectably in airport lines to spot high-stress passengers. Whether that stress is caused by the bomb you're concealing or the fact you're running...
...intelligence forces to infiltrate," says Gustavo de Aristegui, a Spanish terrorism expert and the author of Jihad in Spain. "But they're realizing that ... someone with a Western last name and blue eyes is going to raise fewer suspicions. Converts can be virtually impossible to detect, especially if they have not revealed their conversion to their family...
...understand what the iControl system does, you have to hear a list of its many devices. There are wired and wireless cameras and battery-powered sensors that detect motion, the opening and closing of doors, even the presence of water or freezing temperatures. There are carbon-monoxide and smoke alarms, a wearable "panic pendant" as well as a panic wristwatch. You can get automated light dimmers that plug into power sockets, and even a thermostat...
