The use of full-body scanners at airports has raised concerns about privacy, particularly regarding the visibility of passengers' private parts. While older scanners produced detailed images, including naked images of travellers, newer machines use Advanced Imaging Technology (AIT) that displays a generic avatar with indicators for areas requiring further inspection. This technology respects privacy while maintaining safety, but issues may arise for transgender individuals whose bodies do not match the scanner's default settings. Piercings in intimate areas can also be detected, leading to potentially humiliating and unethical situations.

What You'll Learn
Old airport scanners showed naked images
Old airport scanners used to show naked images of passengers, which was a massive invasion of privacy and a contentious issue. These scanners were phased out within a decade due to privacy infringements. Today, scanners use a generic avatar with yellow or red blocks over areas that need further investigation. This article will explore the evolution of airport scanners and address concerns about privacy and safety.
The Evolution of Airport Scanners
Airport scanners have undergone significant changes over the years. The old scanners, known as backscatter scanners, produced detailed images of a person's body, including private parts. This led to concerns about privacy and health, with critics calling the imaging a virtual strip search without probable cause. As a result, these scanners were removed from airports by 2013 in the US and by 2015 in the UK.
New Scanners Prioritise Privacy
Today's airport scanners use Advanced Imaging Technology (AIT) and millimeter wave imaging to ensure passenger privacy. Instead of displaying a person's unique image, the scanners generate a generic avatar or "gingerbread man" outline with boxes indicating areas of concern. This technology does not pick up size, weight, or height, addressing previous concerns about body image detection.
Addressing Privacy and Safety Concerns
The new scanners balance privacy and safety by detecting both metallic and non-metallic objects without revealing intimate details. Passengers who are concerned about privacy can opt for a traditional pat-down instead of the scan. Additionally, the Transportation Security Administration (TSA) has stated that the scanners cannot store images of passengers and that any images captured during testing are not used on production systems.
While old airport scanners showed naked images, the current technology prioritises passenger privacy while maintaining effective security measures. The use of generic avatars and advanced imaging technology ensures that intimate details are not revealed during the scanning process. As technology continues to evolve, we can expect even more effective and privacy-preserving solutions in the future.

New scanners use generic avatars
Going through an airport body scanner can be intimidating and embarrassing, and it may seem like an invasion of your privacy. Airport scanners today use Advanced Imaging Technology (AIT), which shows a neutral avatar of your body without all the bumps and curves in various places. These scanners will not show your private parts. Instead, they use generic avatars with yellow or red blocks over areas that need further investigation through a pat-down or inspection. These blocks indicate a foreign object or irregularity detected by the scanner's program and gender defaults.
The Transportation Security Administration (TSA) previously used backscatter scanners by Rapiscan Systems, which produced naked images of travellers, effectively like a virtual strip search. These scanners were phased out within a decade due to privacy infringements. The new scanners use AIT, which provides a more neutral and less invasive way to screen passengers.
The AIT scanners have two gender defaults, which can pose issues for transgender or transitioning individuals. If a traveller's body does not match the scanner's default settings, it may flag something suspicious in the groin or chest area. This can be frustrating and embarrassing for both the traveller and the TSA official. However, the TSA officer will need to follow standard operating procedures, which do not include asking about pronouns.
While the new scanners use generic avatars to protect privacy, they are still effective at detecting foreign objects or anomalies. They can detect piercings, especially if they are large or made of metal, and TSA officials will usually do a pat-down in these cases. The scanners can also detect indications of drugs or explosives and provide visual clues of drugs hidden under clothes or in baggage. Overall, the new scanners balance privacy and safety, ensuring a smoother travel experience for passengers while maintaining aviation security.

Scanners can detect piercings
Airport scanners use Advanced Imaging Technology (AIT) to show a neutral avatar of your body with yellow or red blocks over areas that need further investigation. This means that scanners will not see your private parts, but they can detect piercings, especially if they are large or made of metal. If a foreign object is detected, a TSA official will usually do a pat-down. In some cases, a TSA officer may request that the piercing is removed.
To avoid this potentially humiliating and unhygienic process, some people opt for a plastic retainer or hider piercing when travelling. However, if you have a new piercing that is still healing, it is recommended to delay your travel plans, as the piercing should not be jostled.
It is important to note that the experience may vary depending on the technology used and the gender defaults chosen by the TSA officer. For example, transgender or transitioning individuals may be flagged as having something suspicious in their groin or chest area due to the scanner's default settings.
While airport scanners can detect piercings, they are primarily designed to identify concealed items and potential threats to aviation safety. They can detect metallic and non-metallic objects, as well as organic materials such as food, paper, liquids, drugs, and explosives.

Trans bodies may not match scanner defaults
Airport body scanners use Advanced Imaging Technology (AIT) that shows a neutral avatar of the scanned person's body. The technology is based on two gender defaults, and a TSA official indicates the gender of the person being scanned as they enter the scanner. The scanner will detect anomalies if the person's body does not fit into the prescribed range for their indicated gender.
Trans bodies may not match the scanner's defaults. For example, a transgender person who looks female but has male genitalia will be flagged as having something suspicious in their groin. The same could happen to a transgender person classified as male but developing breasts from hormone treatment. This can be a frustrating and embarrassing experience for both the traveller and the TSA official.
To address this issue, the TSA is replacing its current "Advanced Imaging Technology" scanners with technology that will not be based on gender. The new scanning technology will “advance civil rights and improve the customer experience of travelers who previously have been required to undergo additional screening due to alarms in sensitive areas,” according to the TSA.
In the meantime, transgender travellers can opt for TSA PreCheck, which allows participants to go through a simple metal detector rather than a full-body scanner.

Scanners can detect drugs
While airport body scanners will not see your private parts, they can detect piercings in your intimate areas, especially if they are large or metallic. In such cases, a TSA officer may request that you remove the piercing or perform a pat-down.
Airport baggage scanners, on the other hand, can detect drugs. They can see detailed images of your luggage contents, including metallic and non-metallic objects, and organic materials. They do this by releasing X-rays that pass through the bag, calculating the mass and density of the contents. While they may not always be able to establish what the objects are, they can provide visual clues of drugs hidden in baggage or under clothing. For example, organic materials like food, paper, or drugs appear as shades of green or lighter colors.
Passengers suspected of swallowing drugs may be scanned with a full-body X-ray machine, which can detect packages in the stomach, even if they are contained in plastic or glass bottles.
The most common type of scanner found in airports today is the Attenuation Imaging (ATI) scanner, which guarantees privacy by showing only a generic outline without identifying gender or body type. These scanners can detect non-metallic objects, making them useful for detecting explosives and drugs.
Overall, while airport scanners may not directly identify drugs, they provide visual clues that, combined with the skills of trained security officers, can effectively detect drugs and other potential threats.

Frequently asked questions
Yes and no. Backscatter scanners, which were installed in U.S. airports in 2010, produced an image of a person's naked body, including their private parts. However, these scanners were removed from U.S. airports by 2013 due to concerns over privacy.
Airports now use millimeter-wave scanners, which produce a cartoon-like image of the person being scanned. While the computer interpreting the scan can "see everything", the image shown to the TSA agent is a generic "Ken doll" figure with any detected items overlaid on it.
Airport body scanners are designed to detect both metallic and non-metallic threat items, such as weapons or explosives.
If you have a medical device or anything else on your body that you think will set off the scanner's sensors, you should let the TSO know before entering the machine.
