Under test: New airport “full body” scanner is not so intrusive.

Airport Body scanners

The Transportation Security Administration TSA, for its acronym in English) on Tuesday tested a new “Scanner” body, at the  McCarran International Airport in Las Vegas. The scanner has a lower cost than others.

Critics have complained that the normal scanner systems that capture images of the whole body of people violate their privacy, but Dwayne Baird, spokesman for the TSA, said that the new scanner and its software, introduced in the day, is not so intrusive.

The new scanner allow managers to find out the same things about the passangers but uses a more general view, without revealing details of the body.

He added that the issue is whether TSA can improve measures of protection of privacy without sacrificing security levels.

There are nearly 500 “full body” scanners in use in 78 U.S. airports. The system displays the silhouette of a traveler in a computer screen, and can reveal hidden weapons or explosives.

In the screens the inspectors can not distinguish a person’s face, and the images are seen in a private room, but many people believe that these systems are revealing too much about what some people wear under clothing.
