Less-revealing airport scanner software debuts at BWI

New software that displays less intimate physical images is being installed in security checkpoint scanners at Baltimore-Washington International Marshall Airport this week.

They show the human form in a gray, cookie-cutter image rather than the more revealing depictions that caused an uproar last fall when a new generation of scanners was installed nationwide.the outcry

The Transportation Security Administration responded by developing and testing the new software. Reagan National Airport was one of three locations where it underwent testing. It works on millimeter wave scanners, one of two types of body scanners widely introduced last year. All of the new machines at BWI are millimeter wave.

Software for units that use backscatter technology is still being developed, the TSA said. Both work by bouncing X-rays or radio waves off skin or concealed objects.
