[ti:Orlando International Airport to Scan Faces of US Citizens] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.24]Florida's busiest airport will be the first in the country [00:05.72]to require a face scan of passengers on all arriving and departing international flights. [00:15.13]Officials there say all passengers, including U.S. citizens, will be scanned. [00:23.48]Orlando International Airport's expected policy worries some privacy advocates. [00:32.12]They say there are no rules in place for dealing with the information taken from the scans. [00:40.40]Also, there is no system for assisting a passenger [00:45.04]who is wrongly prevented from getting on an airplane. [00:49.96]Airports in Atlanta, Boston, Chicago, Houston, Las Vegas, Miami, New York [00:58.50]and Washington already use face scans for some departing international flights. [01:06.72]However, they do not scan all international travelers like the airport in Orlando plans to do. [01:15.68]The image from the face scan is compared [01:18.76]to a Department of Homeland Security biometric database. [01:24.52]The department has images of people to confirm travelers' identities. [01:31.24]Harrison Rudolph is with the Center [01:33.81]on Privacy & Technology at the Georgetown University Law Center. [01:40.12]He said U.S. citizens at these airports can refuse to be scanned. [01:46.08]But the agency does not seem to be letting people know they can refuse, he noted. [01:53.02]Jennifer Gabris, a spokeswoman for the U.S. Customs and Border Protection Agency, [02:00.10]wrote the Associated Press about the policy. [02:04.08]U.S. citizens at the Orlando airport can refuse to be scanned [02:09.80]if they do not want to provide their photograph, she wrote. [02:14.76]However, a notice about a possible rule change for the program [02:20.24]says "U.S. citizens may be required to provide photographs [02:25.84]upon entering or departing the United States." [02:30.68]Rudolph said the Orlando announcement [02:33.62]marks an increase in the face scan program. [02:38.64]"We're not talking about one gate," he said. [02:42.51]"We're talking about every international departure gate, [02:46.48]which is a huge expansion of the number of people who will be scanned. [02:53.04]Errors tend to go up as uses go up." [02:58.20]Orlando International Airport had about 6 million international passengers in the past year. [03:07.40]Rudolph said he is worried about the face scans' exactness. [03:12.88]Some research shows they are less exact with racial minorities, women and children. [03:20.92]Some researchers say this is because pictures used in the face-scanning software [03:28.12]underrepresent minorities, women and young people. [03:33.80]Last month, two U.S. senators sent a letter to the Department of Homeland Security, [03:40.88]which is home to the border protection agency. [03:45.72]Senator Ed Markey of Massachusetts and Mike Lee of Utah [03:51.20]urged that official rules be put in place before the program is expanded. [03:58.56]Official rules, the senators explained, [04:01.84]would help Americans understand and accept the program. [04:07.28]They noted that this is important because it would affect [04:10.77]every American leaving the country by airport. [04:15.64]I'm Susan Shand. [04:17.56]更多听力请访问51VOA.COM
