A software upgrade that the TSA has been testing in airports in Las Vegas, Atlanta and Washington since February would instead create a generic human form (as shown above) and indicate if the scanner detects a hidden object under the clothing. The technology would also show the TSA agents on what part of the body the object has been found.
As with the current system, if the scanner detects a hidden object, TSA agents will peform additional screening. If nothing is found, the scanner clears the passenger to move on.
“This software upgrade enables us to continue providing a high level of security through advanced imaging technology screening, while improving the passenger experience at checkpoints,” TSA Administrator John Pistole said.
It will take months to complete the tests. Link -via The Daily What Geek
