Senators seek to stop expansion of airport facial scans

WASHINGTON (Reuters) - Two U.S. senators on Thursday urged federal authorities to halt the planned expansion of a $1 billion airport facial scanning program, saying the technology used to identify travelers on some flights departing from nine U.S. airports for international destinations may not be not accurate enough and raises privacy concerns.

Congress has approved the use of the program for non-U.S. citizens, but never expressly authorized its use for Americans. The Department of Homeland Security has said the system is needed to prevent travelers from leaving the country using someone else’s identity and to prevent visitors to the United States from overstaying their visas.

Senators Mike Lee, a Republican, and Edward Markey, a Democrat, in a letter to Department of Homeland Security Secretary Kirstjen Nielsen, raised concerns that too many travelers would be inconvenienced by faulty scan results and questioned why Americans are being subjected to the screens, known as biometric exit detection technology.

In the letter, they raised objections to expanding the program beyond the nine airports where it is already in use.

“We request that DHS stop the expansion of this program and provide Congress with its explicit statutory authority to use and expand a biometric exit program on U.S. citizens,” the senators wrote. “If there is no specific authorization, then we request an explanation for why DHS believes it has the authority to proceed”
