  Behavioral Screening -- The Future Of Airport Security?December 02, 2008 08:54 Keep your shoes and belts on -- waiting in long airport security lines to pass through metal detectors may soon be a thing of the past.

Security experts say focus is shifting from analyzing the content of carry-ons to analyzing the content of passengers' intentions and emotions.

"We are seeing a needed paradigm shift when it comes to security," says Omer Laviv, CEO of ATHENA GS3, an Israeli-based security company.

"This 'brain-fingerprinting,' or technology which checks for behavioral intent, is much more developed than we think."

Nowhere is the need for cutting-edge security more acute than Israel, which faces constant security threats. For this reason, Israel has become a leader in developing security technology.

Several Israeli-based technology companies are developing detection systems that pick up signs of emotional strain -- a psychological red flag that a passenger may intend to commit an act of terror. Speedier and less intrusive than metal detectors, these systems may eventually restore some efficiency to the airplane boarding process.

One firm, WeCU (pronounced "We See You") Technologies, employs a combination of infra-red technology, remote sensors and imagers, and flashing of subliminal images, such as a photo of Osama bin Laden. Developers say the combination of these technologies can detect a person's reaction to certain stimuli by reading body temperature, heart rate and respiration -- signals a terrorist unwittingly emits before he plans to commit an attack.
