To: Frederick Langford who wrote (15140 ) 4/7/2002 10:38:43 AM From: Susan G Respond to of 26752 High-Tech Identity Checks By DAVID J. WALLACE April 7, 2002 (NY Times) ATTEMPTS to improve airport security with new technology have led to tools for identifying people using iris scans, handprints and even cellphones to track movements of passengers and airport personnel. Some innovations also promise customer-service improvements, such as notifying passengers of changes in departure times or gates by cellphone or pager instead of an unintelligible public address speaker. At Billund Airport, Denmark's second busiest gateway, a wireless network was tested for several weeks in February using a voluntary database containing passengers' names, addresses, passport numbers and mobile telephone numbers. Large blue tags that passengers either carried or attached to their carry-on luggage and then surrendered at boarding allowed them to be tracked by airport security. The system, developed by Red-M, a British company, and BlueTags of Denmark, uses Bluetooth computing technology to track sensors. It allows security personnel to see if a tagged bag is somewhere suspicious or if someone entered the wrong terminal or gate, said Laura Cleveland, a Red-M spokeswoman. A handprint identification system used in some airports in the United States, and in Canada and Israel has sped volunteers through passport control since the mid-1990's. At Heathrow Airport, Virgin Atlantic Airways and British Airways are testing an iris-scan device that stores a similar database of enrolled passengers' unique eye characteristics. The five-month trial, which ends in June, may attract up to 2,000 frequent fliers, said Wendy Buck, a Virgin Atlantic spokeswoman. "There may be security implications later on, but the goal for Virgin Atlantic was really to improve the customer experience, and this should speed people's travels through Heathrow," she said. Other airports are testing facial recognition software or equipping law enforcement personnel with encrypted e-mail systems to supplement walkie-talkies or cellphones. IPix, a computer-assisted system of 360-degree image viewing developed for the Department of Energy and NASA and first commercialized in part for real-estate virtual tours on the Web, is being tested as a means of providing improved security video of concourses and passenger areas. Internet Pictures Corporation, the company that sells iPix, is testing a series of cameras at the Knoxville, Tenn., airport that provide 360-degree by 180-degree views with no blind spots for live and archival viewing of the airport, said Stu Roberson, the company's senior vice president for worldwide marketing. IPix cameras can also be teamed with pattern-recognition software to alert guards to unusual occurrences. There are limitations to the way technology is currently being used, said Rick Charles, head of the aviation studies program at Georgia State University. Voluntary scans recognize only "good" travelers, while databases with photos and fingerprints of known criminals are underused. "One reason I like fingerprints is the inability to lose, sell or counterfeit them," he said. "At the present time, you can fool a facial recognition system with a pair of sunglasses." nytimes.com
