Airport body scanners are designed to detect masses either on your body or hidden inside your clothes. The scanners use waves to create an image, and the waves that bounce off the body could reveal if someone is carrying things under their clothing. While these scanners do not see under the skin, they can reveal your entire body, including breasts, genitals, and buttocks. However, privacy concerns have been raised about these scanners, and as a result, the Transportation Security Administration (TSA) has ended contracts with manufacturers of scanners that produce naked images of travelers.

Full-body scanners show a clear outline of passengers' genitals
Full-body scanners at airports have been the subject of much debate and controversy since their introduction. One of the primary concerns surrounding these scanners is their ability to reveal intimate details about passengers' bodies, including a clear outline of passengers' genitals.
The early versions of full-body scanners, also known as "backscatter" machines, used X-ray technology to create detailed images of passengers' bodies. These images were often in black and white and revealed not just concealed items but also passengers' naked bodies, including their genitals. This led to significant privacy concerns and fears that TSA workers might preserve or distribute these images. While manufacturers and security entities assured the public that the images could not be stored, transmitted, or printed, the concerns remained.
In response to the privacy outcry, the Transportation Security Administration (TSA) took steps to address the issue. They ended their contract with Rapiscan Systems, the manufacturer of the nude-image scanners, and transitioned to a less invasive model. The new scanners use non-imaging Automated Target Recognition (ATR) software, which creates a generic image of the passenger, similar to a cartoon or stick figure, while still highlighting potential foreign objects.
Despite these changes, some people still have mixed feelings about full-body scanners. While the scanners no longer display detailed images of passengers' genitals, some argue that even the generic stick-figure images constitute a virtual strip search and violate privacy rights. Additionally, there are concerns about the effectiveness of these scanners in enhancing security, with some questioning whether they are worth the time and resources invested in them.
It is important to note that passengers do have the right to opt out of the full-body scan and request an alternative form of screening, such as a pat-down, as mandated by law in certain countries. However, opting out may lead to additional time spent during the security process.

TSA agents view the images in a separate room
The use of full-body scanners at airports has raised concerns about privacy and security. While these scanners are designed to enhance security by detecting masses or objects on a person's body or hidden underneath their clothing, they have also been criticised for producing revealing images of individuals, including their genitals.
In response to these concerns, the Transportation Security Administration (TSA) has taken steps to address privacy issues. One measure involves TSA agents viewing the images in a separate room, away from the individuals being scanned. This setup is intended to provide a level of anonymity and reduce the potential for ogling or invasion of privacy.
The TSA has also worked with manufacturers to implement blurring techniques in the imagery of sensitive areas, aiming to further protect the privacy of individuals. Additionally, the TSA has emphasised that the images cannot be stored, transmitted, or printed, and are immediately deleted after being viewed.
Despite these assurances, privacy rights activists have criticised the use of full-body scanners, likening them to virtual strip searches. As a result, the TSA has made moves to terminate contracts with manufacturers that produce scanners generating naked images, such as Rapiscan Systems.
It's important to note that while the TSA has taken steps to balance security and privacy, the presence of full-body scanners and the nature of the images they produce continue to be a topic of debate among travellers and privacy advocates.

The scanners can detect masses on the body or hidden inside clothing
Airport body scanners are designed to detect masses on the body or hidden inside clothing. They do this by bouncing electromagnetic waves off the traveller to provide an animated image where a suspicious item might be located. The scanners use radio waves to create an image, which can detect objects hidden under clothes.
The scanners are large machines that work alongside metal detectors and baggage X-ray machines at the security point on the way to the departure lounge. They scan the entire body for concealed weapons, explosives, and contraband. The scanners can detect masses on the body, such as protrusions, skin lesions, or piercings, and can also identify masses hidden inside clothing, such as drugs or hazardous liquids in pockets.
The use of full-body scanners in airports has been controversial due to privacy concerns. Early versions of the scanners produced detailed images of passengers' bodies, including naked images, which could be viewed by TSA agents. This raised concerns about virtual strip searches and the potential for images to be stored or misused. In response to these concerns, new scanners have been developed that use non-imaging Automated Target Recognition (ATR) software, which creates a generic image of the body and highlights potential foreign objects without revealing anatomical details.
While the new scanners address privacy issues, they are not perfect. They can malfunction, and certain items of clothing or hair accessories can trigger false positives. Additionally, the scanners do not see under the skin, so they would not detect items stashed inside a body cavity. Overall, while the scanners have their limitations, they are an important tool for enhancing security and detecting potential threats.

The scanners cannot see under the skin
While full-body scanners at airports have been the subject of controversy, it is important to understand that they are not capable of seeing under the skin. Malvini Redden, an expert in airport security, confirms this limitation of the scanners, stating that they "don't see under the skin". This means that items stashed inside body cavities, such as drugs or hazardous liquids, would not be detected by the scanners.
The primary purpose of airport body scanners is to detect masses or objects either on your body or hidden underneath your clothing. They use waves, such as millimeter waves or backscatter X-rays, to create an image that reveals concealed items. However, they do not have the capability to see beneath the surface of the skin.
The early versions of full-body scanners raised significant privacy concerns as they produced detailed images of a person's naked body, including their genitals. These images were considered by many to be a virtual strip search and an invasion of privacy. As a result, manufacturers have worked to address these concerns by implementing privacy protections.
The newer scanners now use non-imaging Automated Target Recognition (ATR) software, which creates a generic image that resembles a cartoon or stick figure. This image highlights potential foreign objects on the traveler's body while preserving privacy. The machines are designed to detect non-metallic items that metal detectors may miss, ensuring a more comprehensive security check.
While the scanners cannot see under the skin, it is important to note that certain items, such as body piercings, hair extensions, or underwire bras, may still trigger the scanner. In such cases, a pat-down inspection by a same-gender TSA officer can be requested. Additionally, individuals with medical conditions or special circumstances can opt for a private screening with a specialist upon request.

Privacy rights activists have complained that the scanners constitute a virtual strip search
Privacy rights activists have complained that airport body scanners constitute a virtual strip search. The American Civil Liberties Union (ACLU) has called for the implementation of effective security policies that pose the most minimal threat to Americans' privacy. ACLU Washington Legislative Office policy counsel and former FBI agent Michael German said:
> The government must find out what went wrong and what more can be done to protect our nation against terrorism... But while it's important to react quickly, it's also important to react wisely and to adopt procedures that will be both truly effective and the least invasive to Americans' privacy. Electronic strip-searching of innocent people, racial profiling, and bloated, poorly managed terrorist watch lists do not stop terrorist attacks, but they do infringe upon Americans' rights and waste valuable resources.
Indeed, full-body scanners present serious threats to personal privacy and are of unclear effectiveness. They produce strikingly graphic images of passengers' bodies, essentially taking naked pictures that reveal not only private body parts but also intimate medical details like colostomy bags. ACLU's Hina Shamsi has argued that "every move President Trump has made... has been escalatory and inflammatory".
Passengers are able to see the viewing monitor throughout the scanning process, and the images cannot be stored. However, privacy rights activists remain concerned about the potential misuse of such images.
