Airport body scanners have evolved since their early days, with the Transportation Security Administration (TSA) in the US striving to balance passenger protection with privacy. While older machines allowed officers to see passengers' naked bodies, newer scanners use Advanced Imaging Technology (AIT) paired with Automated Target Recognition (ATR) software to detect metallic and non-metallic threats without displaying detailed anatomical images. Although the machines can still see under clothes, what officers observe is no more revealing than a stick figure, focusing on threats rather than exposing passengers' privacy.

Airport scanners can detect foreign objects on the body
Airport body scanners have evolved over the years, with older machines raising privacy concerns as they revealed a person's silhouette and the outlines of their underwear. These older machines used backscatter technology, which produced graphic, almost naked images of passengers, leading to public outcry and questions about their legality.
In response to these concerns, the Transportation Security Administration (TSA) retired the backscatter machines in 2013 and introduced a new system: Advanced Imaging Technology (AIT) paired with Automated Target Recognition (ATR) software. This new technology uses electromagnetic millimeter waves to detect a wide range of metallic and non-metallic threats, including weapons and plastic explosives.
While the current machines can still "see" under clothes in the sense that they can detect foreign objects on the body, what TSA officers see is no more revealing than a stick figure on a screen. The machines send millimeter waves through clothing, which reflect off the passenger's skin and any concealed items, creating an image that is interpreted by the machine. This image is not stored and the officer viewing it is located remotely, unable to see the identity of the passenger being screened.
Some passengers may still be required to undergo AIT screening if they have been selected for enhanced screening prior to their arrival at the security checkpoint. This could be due to certain characteristics that do not match the "standard", such as wearing prosthetics or binders, which will be flagged for further screening. Passengers who are uncomfortable with the scanner can opt out, but this usually results in a physical pat-down instead.

Scanners can see through clothing to reveal metallic and non-metallic objects
Airport body scanners have evolved over the years, with the Transportation Security Administration (TSA) in the US striving to balance passenger protection with privacy concerns. In 2009, the TSA introduced whole-body imaging technology at six airports, with plans to expand further. These scanners could see through clothing to detect metallic and non-metallic objects, including weapons or plastic explosives. They also revealed a person's silhouette and the outlines of underwear, causing an uproar among privacy advocates.
In response, the TSA implemented safeguards, such as having officers located away from the checkpoint view the scans. Additionally, the TSA introduced Advanced Imaging Technology (AIT) paired with Automated Target Recognition (ATR) software. This new system could detect both metallic and non-metallic threats without displaying detailed anatomical images. Instead, officers would see a stick figure-like image with potential threats flagged.
Today, airport body scanners use electromagnetic millimeter waves, which penetrate clothing and reflect off a passenger's skin and any concealed items. The waves bounce back an image interpreted by the machine, focusing on threats rather than exposing passengers' privacy. While the technology has improved, some passengers still opt for a physical pat-down instead of the scanner, finding it less invasive.
While airport scanners can technically ""see"" under clothes by detecting foreign objects, the images interpreted by officers are no more revealing than a stick figure, ensuring passengers' privacy.

Scanners can flag unexpected items as potential threats
Airport body scanners have evolved over the years, and today's machines rely on electromagnetic millimeter waves. While the machines can technically "see" under your clothes in the sense that they detect foreign objects on the body, what TSA officers see is no more revealing than a stick figure on a screen. The scanners are focused on threats, not on exposing your privacy.
The scanners use a technology called Advanced Imaging Technology (AIT) for full-body scans at airport checkpoints. It's a millimeter-wave scanner that detects a wide range of metallic and non-metallic threats in a matter of seconds. The machines send millimeter waves toward a passenger's insides, and these waves go through clothing and reflect off the passenger's skin and whatever else is concealed. The waves then bounce back an image, which is interpreted by the machine.
However, the imaging technology is quite sensitive and can flag some unexpected items and substances as potential threats. For example, a 2016 case study revealed that scanning devices can misinterpret cysts and other skin lesions as foreign objects. Even sweat can set off the machines. Similarly, trans people may face issues as the scanning process flags penises and binders as suspicious.
Amid mounting criticism of older scanner models, the TSA pivoted in 2013, officially retiring backscatter machines and introducing a new system: Advanced Imaging Technology (AIT) paired with Automated Target Recognition (ATR) software. This new setup allowed scanners to detect both metallic and non-metallic threats without displaying a detailed anatomical image.

Scanners can detect a lack of bumps where there should be bumps
Airport body scanners use Advanced Imaging Technology (AIT) and Automated Target Recognition (ATR) software to detect metallic and non-metallic objects on a person's body. The scanners use electromagnetic millimeter waves that pass through clothing and reflect off the skin and other concealed items, creating an image that is interpreted by the machine.
While the scanners cannot detect objects inside the body or under the skin, they can identify a lack of bumps where there should be bumps. This aspect of the scanning process can be problematic for transgender people, as scanners may flag penises and binders as suspicious, leading to further invasive searches.
To address privacy concerns, the Transportation Security Administration (TSA) has implemented safeguards. For example, the officer viewing the scan is located remotely and cannot see the passenger being screened. Additionally, the TSA offers alternatives to the body scanner, such as physical pat-downs or metal detectors, and passengers can opt out of the body scanner if they prefer.
The use of body scanners at airports has evolved over time, with older machines using backscatter technology that created detailed images of passengers' bodies, raising privacy concerns. However, the TSA retired these machines in 2013 and introduced the new AIT and ATR system, which focuses on detecting threats without displaying detailed anatomical images.
While the current scanners can still detect foreign objects under clothing, the images seen by TSA officers are no more revealing than a stick figure, aiming to balance security with passenger privacy.

Scanners can be opted out of, but this results in a physical pat-down
Airport body scanners have evolved over the years, with older machines raising concerns about privacy. The Transportation Security Administration (TSA) has since implemented safeguards for passenger privacy, and the current machines do not show a naked body on the screen. While the machines can "`see`" under clothes in the sense that they detect foreign objects, what TSA officers see is no more revealing than a stick figure on a screen. The MMW and backscatter scans intentionally blur facial features, and the security officer viewing the images sits in a remote location where they cannot identify the passengers. These images are deleted after viewing and have "zero storage capability".
Despite these privacy measures, passengers may still feel uncomfortable with the scanner. Opting out is allowed, but this usually results in a physical pat-down instead, a process many find even more uncomfortable. The TSA has made efforts to be more transparent and responsive to passengers' concerns, with programs like TSA Cares designed to support passengers with medical conditions and disabilities, as well as provide customized assistance for parents or anyone needing additional help during screening.
In addition to privacy concerns, there are also concerns about the accuracy of the machines. While they can detect both metallic and non-metallic threats, they can also flag some unexpected items and substances as potential threats. For example, a 2016 case study revealed that scanning devices can misinterpret cysts and other skin lesions as foreign objects. Even sweat can set off the machines.
For those who are particularly concerned about privacy or the accuracy of the machines, there are a few alternatives to the body scanners. Some airports offer metal detectors instead of body scanners, and passengers can also decline AIT screening in favour of a physical screening. However, some passengers may be required to undergo AIT screening if their boarding pass indicates that they have been selected for enhanced screening prior to their arrival at the security checkpoint.
