What You'll Learn
The TSA's facial recognition technology
The Transportation Security Administration (TSA) has been rapidly expanding a pilot program implementing facial recognition technology (FRT) into its security screening checkpoints at airports across the United States. The program, which began in 2020, has raised some concerns about privacy and civil liberties. Nevertheless, the TSA maintains that the technology is crucial for identity verification and enhancing security effectiveness while improving traveller convenience.
TSA introduced facial recognition technology into the screening process at select airports to automate the current manual ID credential-checking process. The technology is used to verify that the person standing at the checkpoint is the same person pictured on the identification document (ID) credential. Photos are not stored or saved after a positive ID match has been made, except in a limited testing environment for evaluating the technology's effectiveness. The TSA uses second-generation Credential Authentication Technology (CAT-2) scanners as travellers enter the screening process. This technology assists Transportation Security Officers (TSOs) in authenticating a traveller's ID, flight status, and vetting status.
The CAT-2 units are currently deployed at nearly 84 airports nationwide, including John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), Salt Lake City International Airport (SLC), and William P. Hobby Airport (HOU), with plans to expand to over 400 federalized airports in the coming years. The TSA's Chief Administrator has stated that the program will likely become a mandatory element of airport screening in the future, despite the fact that travellers can currently opt out of the process.
The TSA is committed to using the highest-performing matching algorithms and designing solutions to mitigate the impact of environmental and technical variability. While the technology has been found to be highly accurate, with an overall accuracy rate of 99%, there are concerns about bias in the system. Studies have shown that it misidentifies women of colour and Black individuals at higher rates than other groups. As a result, lawmakers and privacy rights advocates have expressed alarm about the increasing use of government surveillance tools and their potential impact on civil liberties.

Concerns about bias and privacy
Facial recognition technology is being piloted at airports to streamline identity verification and enhance security. However, this technology has sparked concerns about bias and privacy, with critics arguing that it poses a threat to civil liberties and could exacerbate discrimination against marginalised communities.
One key concern is the potential for bias in the algorithms underpinning facial recognition systems. Studies have shown that these technologies misidentify women, people of colour, and transgender or non-binary individuals at higher rates, with some algorithms failing to identify people with darker skin tones up to 100 times more often than white individuals. This bias can lead to unfair treatment and discrimination against specific demographic groups.
The use of facial recognition technology in airports also raises privacy concerns, particularly regarding the collection and storage of biometric data by government agencies. While the Transportation Security Administration (TSA) has stated that they do not store biometric data from the pilot, critics worry that this policy could change in the future. There are also fears that hackers could gain access to sensitive biometric information, compromising the privacy and security of individuals.
Additionally, critics argue that the opt-out option for passengers who do not wish to participate in facial recognition screening may not be practical due to time constraints and worries about missing flights. There are concerns that opting out could lead to further suspicion and negative repercussions for passengers.
To address these concerns, experts recommend conducting comprehensive research on bias in facial recognition systems and pushing for legislative action to regulate their deployment and development. Transparency in the training and use of these technologies is also essential to mitigating potential biases and privacy risks.

Airports using facial recognition
The use of facial recognition technology in airports is becoming more common, with the Transportation Security Administration (TSA) introducing it into the screening process at select airports. The TSA uses facial recognition to verify that the person standing at the checkpoint matches the identification document (ID) provided. This technology is designed to enhance security and improve the traveller experience, making it more convenient and efficient.
While the TSA claims its program is 97% effective across all demographic groups, there are concerns about the potential for bias and the impact on privacy and civil liberties. Critics argue that the technology could boost discrimination against marginalised communities, with studies showing that it misidentifies women of colour and transgender individuals at a higher rate.
Despite these concerns, the TSA plans to expand its program to over 400 airports in the coming years. Currently, TSA's Credential Authentication Technology (CAT-2) scanners are deployed at nearly 84 airports nationwide, including John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), and Salt Lake City International Airport (SLC).
In addition to the TSA, Customs and Border Protection (CBP) also uses facial recognition technology at airport checkpoints. CBP reports that it has 238 airports using Biometric Facial Comparison Technology, including 14 preclearance locations and 49 international departure locations.

How to opt out of facial recognition
Facial recognition technology is becoming increasingly common at airports around the world. This technology is often used to speed up processes such as checking in, dropping off luggage, getting through security, boarding, and customs. While this technology is convenient, it is not without its issues. Studies have shown that facial recognition software misidentifies women of colour and transgender people at a much higher rate than white men.
If you are concerned about this technology and wish to opt out, there are a few things you can do. Firstly, it is important to note that opting out is not always obvious and clear signage may not always be present. However, as a U.S. citizen or permanent resident, it is your right to opt out. To do so, simply notify an officer or airline employee at the time of the facial recognition scan that you would like to opt out. They should then process your identification manually by reviewing your travel documents. This may include your passport and ticket, which you can provide to the gate agents at the time of boarding. It is important to note that this manual process may take longer. Additionally, you may have to opt out multiple times throughout your journey, from arriving at the airport to reaching your airplane seat.
While U.S. citizens and permanent residents can opt out of facial recognition on departing international flights, it is mandatory for non-U.S. citizens. However, anyone, regardless of citizenship, can opt out of facial recognition for domestic U.S. flights. It is worth checking which airports and airlines use this technology, as it is becoming increasingly widespread. Some airports that have implemented facial recognition technology include John F. Kennedy International Airport (JFK), LaGuardia Airport (LGA), Salt Lake City International Airport (SLC), and William P. Hobby Airport (HOU).

The future of airport security
Facial recognition technology in airports works by matching a passenger's current face with their ID photo. In some cases, passengers may not need to present a physical ID, as the system can match their face to an existing gallery of government-issued photos. This process is designed to streamline identity verification, strengthen security, and improve operational efficiency.
While the use of facial recognition technology in airports has the potential to revolutionise the travel experience, there are also concerns and criticisms surrounding its implementation. One of the primary concerns is the potential for bias and misidentification, particularly for women, children, the elderly, and individuals who identify as transgender or non-binary. Studies have shown that facial recognition software misidentifies women of colour more than one-third of the time and has higher error rates for transgender and non-binary individuals. These inaccuracies can lead to discrimination and negative consequences for marginalised communities.
Another concern relates to privacy and the potential threat to civil liberties. Critics argue that the collection and storage of biometric data by government agencies and private companies could infringe on individuals' privacy rights and lead to potential misuse or abuse. However, TSA has stated its commitment to protecting traveller privacy and civil liberties, ensuring that photos are not stored or saved after a positive ID match, and providing travellers with the option to decline facial recognition and choose alternative identity verification methods.
Despite the concerns, the use of facial recognition technology in airports is expected to expand in the coming years. The TSA plans to deploy this technology to hundreds of airports, and major airlines and aviation security agencies worldwide are investing in its development. As the technology advances and gains wider acceptance, it has the potential to significantly impact airport security, making air travel more secure and efficient for passengers.
