New screening software said to be less evasive is now being tested at McCarran International Airport. The Transportation Security Administration says the software is being used on one full-body imaging machine at the Las Vegas facility. Unlike current software, it can detect potential explosives or weapons while displaying a generic image of a passenger without anatomical details. Both passengers and TSA agents can see the image in seconds. The current X-ray system produces a virtual nude image that has led to privacy concerns. TSA Administrator John Pistole says the new software will strike a balance between passenger protection and “further enhance” privacy protections now in place. The new software is also being tested at Washington’s Reagan National and Atlanta International airports.
