“THIS YEAR COULD BE THE “TIPPING POINT” FOR WIDESPREAD BIOMETRICS USE IN AIR TRAVEL”.
“helping to reduce waiting times and stress for travelers,” Harteveldt said.
5. In the United States, major airlines have increasingly invested in facial recognition technology as have government agencies in charge of aviation security. Overseas, a growing number of international airports are installing biometrics-enabled electronic gates and self-service kiosks at immigration and customs. The technology’s adoption could mean enhanced security and faster processing for passengers, experts say. But it also raises concerns over privacy and ethics.
6. Dr. Morgan Klaus Scheuerman, a postdoctoral researcher at the University of Colorado who studies the ethics of artificial intelligence and digital identity, said many questions have emerged about the use of biometrics at airports: How are the systems being trained and evaluated? Would opting out be considered a red flag? What if your documents don’t match your current appearance?
A highly regulated process
7. The TSA, with more than 50,000 officers at nearly 430 airports in the United States, is the main federal agency ensuring the safety of the hundreds of millions of passengers who fly each year. Travelers who are determined to be “low-risk” can apply for TSA’s PreCheck program, which offers expedited security screening at more than 200 domestic airports. PreCheck, which requires an in-person appointment to show documents and give fingerprints, and biometric verification by Clear, a private screening company, have helped to reduce the wait time for screening, but air travelers still must occasionally stand in long queues to get to their gates.
8. The TSA has experimented with facial recognition technology since 2019. Screening verification currently offered at Denver and Los Angeles International Airports and some 30 other airports starts when a photo is taken of the traveler. Then facial recognition software is used to match the image to a physical scan of a license or passport. The photo is deleted shortly afterward, according to the agency. This process, which passengers can opt out of, will be available at some 400 more airports in the coming years, the agency said.
9. Melissa Conley, a TSA executive director overseeing checkpoint technologies, said biometric technology is better than human agents at matching faces rapidly and accurately. “People are not good at matching faces. It’s just known,” Conley said. “Machines don’t get tired.” The process still requires passengers to show their IDs. But the program being tried by Delta, called Delta Digital ID, changes that. With Delta Digital ID, PreCheck travelers can use their faces in lieu of boarding passes and ID at both bag drop and security at La Guardia and four other airports. And Alaska Airlines plans to spend $2.5
billion over the next three years in upgrades, including new bag drop machines.
10. The fastest growing use of facial recognition software at U.S. airports so far has been in security measures for entering and exiting the United States. The growth stems from a 2001 congressional mandate, in the wake of 9/11, requiring the implementation of a system that would allow all travelers arriving and departing the United States to be identified using biometric technology.
11. Overseen by the Customs and Border Protection agency, the biometric system for those entering the United States is in place, and scanned 113 million entries at airports last year. For those leaving the country, the system is available at 49 airports, with the CBP aiming to cover all airports with international departures by 2026. Biometric entry is mandatory for foreign nationals. But biometric exit is currently optional for these travelers. At any border, the biometric process is optional for U.S. citizens, who can instead request a manual ID check.
12. Diane Sabatino, acting executive assistant commissioner for field operations at CBP, said that the system aims to improve security, but she acknowledged rising privacy concerns. Images of U.S. citizens taken during the process are deleted within 12 hours, she said, but photos of foreign nationals are stored for up to 75 years. “We are not scanning the crowd looking for people,” she said. “It’s certainly a privacy issue. We are never going to ask them to sacrifice privacy for convenience.”
13. Biometrics use has already seeped into daily life. People unlock their phones with their faces. Shoppers can pay for groceries with their palms at Whole Foods. But critics believe that the technology’s convenience fails to outweigh a high potential for abuse — from unfettered surveillance to unintended effects like perpetuating racial and gender discrimination.
14. Cody Venzke, senior policy counsel on privacy and technology at the American Civil Liberties Union, said the government had not yet shown a demonstrated need for facial recognition technology at airports and worried about a “nuclear scenario.”
15. The ACLU supports a congressional bill, introduced last November, called the Traveler Privacy Protection Act. Listing concerns over security and racial discrimination, the bill would halt the TSA’s ongoing facial recognition program, and require congressional authorization for the agency to resume it. O
