First US Face Recognition Terminal Opens at Atlanta Airport
A United States airport has become the first in the nation to permit passengers to use facial recognition technology to get on flights.
The system launched last week at Hartsfield-Jackson Atlanta International Airport in the state of Georgia.
The technology can be used by international passengers traveling through a special terminal. Atlanta's Hartsfield–Jackson Airport usually ranks as the world's busiest airport based on the number of passengers.
The terminal is operated by Delta Airlines. But it also serves passengers flying on international carriers Aeromexico, Air France, KLM and Virgin Atlantic Airways.
Delta said in a statement it is the first fully biometric airport terminal to operate in the U.S. The goal of the system is to simplify and speed up the process of presenting documents to get on a flight. The company says passengers can begin using the facial recognition system when they first arrive at the airport.
After the first check-in, passengers can also use face recognition to pass through security and to get on the plane. Delta says the system prevents the need for travelers to present their passport up to four times during the usual check-in process.
Travelers look into a camera that scans their face. This image is then compared against a collection of pictures kept by the U.S. Customs and Border Protection. The agency collects face scans from passports and visas.
The system, however, has raised concerns about privacy. Earlier this year, two U.S. lawmakers sent a letter to the Department of Homeland Security, which is home to the border protection agency.
Senators Ed Markey of Massachusetts and Mike Lee of Utah urged that official rules be put in place before the program is expanded. Official rules, the senators said, would help Americans understand and accept the program.
Jeramie Scott is a lawyer with the Electronic Privacy Information Center. He has called the use of facial recognition at U.S. airports a "massive threat."
Scott placed a statement on Twitter. He said his fear is that the government's facial recognition database of citizens could be used for other purposes without an individual's permission.
"The government now has the power to identify you whenever it wants, without your consent, and even without your knowledge," he said.
Scott added that through facial recognition, the government has created "a digital ID of millions of Americans." He added: "And they did this without a public discussion or consent – taking photos collected for one purpose and using it for another."
John Wagner is deputy executive assistant commissioner of U.S. Customs and Border Protection, or CBP. He told CBS News any U.S. citizen who has privacy concerns can choose not to take part in the facial recognition system. He said this would prevent the airline from collecting a face scan to compare with CBP records.
The CBP says its policy is to remove photos of U.S. citizens from its system once their identities have been confirmed.
Delta says about two percent of passengers using the Atlanta airport terminal have chosen not to use the facial recognition system. Next year, the airline plans to expand its biometric system for international travelers at Detroit Metropolitan Airport in Michigan.

国际旅客经由一个特殊终端系统通行时可以使用这项技术 。由于客流量庞大，亚特兰大哈兹菲尔德-杰克逊机场经常排在世界最繁忙机场首位 。
这个终端系统由达美航空公司运行 。不过该系统也为乘坐墨西哥航空公司、法国航空公司、荷兰皇家航空公司和英国维珍大西洋航空公司的国际旅客提供服务 。
达美航空在声明中表示，这是美国首个全面启用生物识别技术的航站楼 。该系统的目标是简化并加快出示文件的过程，快速完成登机 。达美航空表示，旅客进入机场以后就可以开始使用人脸识别系统 。
在用人脸识别系统办理登机手续之后，旅客还可以用该系统通过安检并登机 。达美航空表示，在常规登机流程中，旅客要出示四次护照才能完成登机，而这个系统避免了这种繁琐的流程 。
旅客只需看向镜头，进行脸部扫描 。系统会将扫描图像与美国海关与边境保护局存档的照片进行对比 。该机构从旅客护照和签证上采集扫描图像 。
但是，这一系统引发了隐私担忧 。今年早些时候，两名美国议员曾致信美国国土安全部，而美国海关与边境保护局隶属于国土安全部 。
马萨诸塞州参议员埃德·马基和犹他州参议员迈克·李要求在这个项目扩大之前出台官方规定 。两位参议员表示，官方规定有助于美国人理解并接受这个项目 。
杰拉米·斯科特是美国电子隐私信息中心的律师 。他认为美国机场使用人脸识别技术会带来“严重威胁” 。
斯科特在推特上发表了一份声明 。他说，他担心政府用公民信息建立的人脸识别数据库会在未得到公民允许的情况下用于其他目的 。
斯科特还说，政府可以通过人脸识别技术创建“数百万美国公民的数字身份 。”他说，“在未经公开讨论或未征得同意的情况下，政府就开始拍摄照片，为某个目的收集信息，而且可能还会将这些信息用于另一个目的 。”
约翰·瓦格纳是美国海关与边境保护局（简称CBP）的副行政助理专员 。他在接受哥伦比亚广播公司的采访时表示，任何对隐私感到担忧的美国公民都可以选择不使用人脸识别系统 。他说，这可以阻止航空公司收集将与CBP的记录进行对比的脸部扫描图像 。
达美航空公司表示，在通过亚特兰大机场航站楼出行的旅客中，有约2%的人选择不使用人脸识别系统 。达美航空计划明年继续推广其生物终端系统，为密歇根州底特律大都会机场的国际旅客提供服务 。
