Airport body scanners are designed to detect metallic and non-metallic threat items, including weapons and explosives. They use Advanced Imaging Technology (AIT) to conduct full-body scans. Older machines, which used backscatter technology, produced detailed images of passengers' bodies, leading to concerns about privacy and safety. These machines were removed from U.S. airports by 2013. Newer scanners use millimeter-wave technology, which generates a generic, cartoon-like outline of the human body, addressing privacy concerns. While these scanners do not reveal pubic hair, they may identify anomalies in hair density, particularly with thick or braided hair, which can trigger further inspection.

What You'll Learn
Old airport scanners showed nudity
Airport body scanners are designed to detect metallic and non-metallic threat items, such as weapons and explosives. While these scanners are necessary for security, they have also raised concerns about privacy. Older airport scanners, in particular, have been criticised for producing detailed images of passengers' bodies, leading to concerns that they amount to a form of digital strip search.
The Transportation Security Administration (TSA) in the United States began using full-body imaging machines in 2010. These machines, known as backscatter scanners, used X-rays to create images of passengers' bodies. While the TSA claimed that employees would not be able to identify passengers based on the images, the public and privacy activists were unconvinced. The machines were deemed invasive, and there were concerns that they violated passengers' privacy.
The backscatter scanners were removed from U.S. airports by 2013 due to these privacy concerns and because they slowed down security checkpoints. They were replaced by millimeter-wave scanners, which produce less detailed, cartoon-like images of passengers. These newer scanners are also considered safer than the backscatter machines, as they do not use X-rays.
While the newer scanners address some privacy concerns, the question of whether airport body scanners violate passengers' privacy remains a subject of debate. Some people may still find the idea of their bodies being scanned in any form uncomfortable, even if the resulting images are generic outlines. Additionally, passengers may be concerned about the potential for discrimination or the targeting of certain groups based on the scanner's interpretation of their anatomy.
To protect their privacy, passengers can request alternative screening methods, such as a pat-down or body search. However, this may not always be a comfortable option, especially for individuals with dysphoria or other sensitive circumstances. Ultimately, while airport scanners are necessary for security, it is important to balance these security measures with respect for passengers' privacy and dignity.

New scanners use generic outlines
Airport body scanners are used to detect items that could pose a threat to the safety of an aircraft and its passengers. These include metallic and non-metallic items such as weapons and explosives.
In the past, airport scanners have raised privacy concerns. Older machines, which used backscatter technology, were able to show a person's naked body. This led to concerns about privacy and the scanners being deemed as "digital strip searches". As a result, these machines were removed from US airports by 2013.
To address privacy concerns, new scanners have been introduced that use generic outlines. These scanners use electromagnetic waves instead of X-rays to generate a rudimentary, gender-neutral figure with mitten hands, a halo of hair, and no nose. This "Gumby-type" image is identical for each person scanned and provides a less revealing representation of the individual. The new scanners still effectively detect weapons and other non-metallic materials while protecting the privacy of passengers.
The Transportation Security Administration (TSA) has installed these new scanners at Logan International Airport, replacing the older scanners that had been in use since 2010. A total of 27 new machines have been installed, and both TSA screeners and passengers can view the images at checkpoints. The TSA has also installed 555 machines with the new software that generates generic body outlines in airports across the country.
While the new scanners offer improved privacy, some privacy advocates have raised concerns about the potential for the machines to record and store images of passengers. The Electronic Privacy Information Center has filed a lawsuit against the Department of Homeland Security, which oversees the TSA, due to the ability of the scanners to record images. The TSA has stated that the function to record images is disabled before the machines are installed in airports.

Scanners can detect hair type
The Transportation Security Administration (TSA) has used various types of scanners over the years, including backscatter scanners and millimeter-wave scanners. Backscatter scanners used very low-energy X-rays to detect items such as weapons or explosives that might be concealed under clothing. These scanners produced detailed images of passengers' bodies, leading to concerns about privacy and safety. As a result, they were removed from U.S. airports by 2013.
Millimeter-wave scanners, which have been in use since 2013, generate a generic, cartoon-like outline of the human body. If threatening items are detected, they are pinpointed on this outline. These scanners are considered safer and less invasive than the backscatter machines.
It is important to note that while scanners can detect items under clothing, the TSA has privacy measures in place to protect passengers' dignity. For example, officers located in a remote area away from passengers viewed the images from the older machines, and the images were not saved or stored but immediately deleted.

Scanners can detect hair accessories
Airport body scanners are designed to detect "metallic and non-metallic threat items," including weapons, explosives, and other items that could be used to harm passengers or the aircraft. Scanners use Advanced Imaging Technology (AIT) to conduct full-body scans at airport checkpoints.
While the primary purpose of these scanners is to identify security threats, they can also detect certain hair accessories. For example, hair clips or thick hair styled in a braid or bun may trigger the scanner and cause it to alert the Transportation Security Officer (TSO). This is because the scanners are sensitive to objects that could conceal prohibited items or be used as weapons.
In addition to security concerns, hair accessories can also be detected by scanners used in the beauty industry. Skin and hair analysis systems employ high-definition cameras and magnification technology to assess hair and scalp health. These scanners can detect hair accessories as foreign objects and may be used to advise clients on the impact of certain accessories on hair and scalp condition.
It is important to note that airport body scanners do not show detailed images of passengers' bodies or private parts. Older machines that used backscatter technology have been replaced due to privacy concerns, and current scanners provide a cartoon-like, less revealing image. While these scanners may detect certain hair accessories and trigger further inspection, they do not expose intimate body parts or personal details.
In summary, airport scanners can detect hair accessories, particularly those that are metallic or could potentially conceal prohibited items. This triggers an alert to ensure the safety of passengers and aircraft, but it does not expose intimate details about an individual's body or personal habits.

Scanners can identify private parts
The older versions of these scanners, called backscatter scanners, used X-rays to produce detailed images of passengers' bodies, including their private parts. These scanners were deemed "digital strip searches" and were removed from US airports in 2013 after users expressed concerns over privacy.
The newer scanners use millimeter-wave technology, which generates a generic, cartoon-like outline of the human body. If threatening items are detected, they are pinpointed on this outline. This outline is less revealing than the images produced by the older backscatter scanners.
While the newer scanners do not show detailed images of private parts, they can still identify abnormalities in body shape, including in the private areas. For example, they can detect the presence of a penis, which may be flagged as suspicious for transgender individuals. In such cases, the individual may be offered a private room for a pat-down, and the process is typically discreet.
