No more naked pictures

Your private parts will soon be private again. In July, the US Transport Security Administration (or TSA) announced that it’ll be installing new software on millimetre-wave Advanced Imaging Technology machines in airports that’ll replace passenger-specific images with a generic outline of a person.

The new software also means that travellers will be able to view the outline just as the TSA officer sees it, that is, it’ll no longer be necessary for a separate officer to view the image in a remotely located viewing room. Potential threat items detected will be indicated on the outline and additional screening will be required; if no threat items are detected, an "OK" will appear on the monitor.

There are nearly 500 millimetre-wave and backscatter imaging machines in 78 US airports. The new software will be installed on 241 millimetre-wave units in coming months; similar software will be tested on backscatter units this fall.
