Airport security advances clash with privacy issues
The New York Times - 05/08/2015
At a mock airport in an underground laboratory here at Northeastern University, students pretending to be passengers head through a security exit in the right direction, while a young man enters going the wrong way. On a nearby computer screen, a newly developed video surveillance software program flags the wayward person and sounds an alarm.
In a lab across the street, researchers are developing a new way to detect explosives using radar.
Just down the hall, a professor and a team of students are working on a scanning system that they hope will speed up security lines. The system uses machines installed in walls or other places to scan passengers as they walk past instead of having them walk individually into a conventional scanning machine.
