Airports have been adopting new technologies to monitor passengers' movements and gather information about them. While some of these technologies are designed to enhance security and convenience, such as full-body scanners and carry-on baggage screening, others have raised concerns among privacy advocates. For instance, the use of facial recognition technology and iris scanners allows airports to identify passengers and track their movements. Additionally, Customs and Border Protection officers have the authority to search electronic devices, including phones and laptops, when entering the country, which has sparked concerns among travelers and led to discussions about digital privacy rights.

What You'll Learn
Full-body scanners
The scanners do not reveal a person's naked body or the inside of their body. Instead, a generic human shape is displayed, without identifying features, resembling a doll or mannequin. This is to protect the privacy of the person being scanned. The scanners are also safe for pregnant people and those with medical devices such as pacemakers.
Passengers can opt out of being scanned and request an alternative method of screening, such as a pat-down or hand search. However, this may involve the removal of clothing and a thorough physical check of the body. It is important to remain polite when opting out of a body scan, as refusing can cause suspicion and flag a passenger as disruptive.
While full-body scanners are now considered safe, there were concerns about earlier machines used between 2009 and 2013. The Rapiscan backscatter machines used during this time produced low-energy X-rays, which raised concerns about increased radiation exposure. These machines have since been replaced by millimetre-wave scanners, which emit far less energy than a mobile phone.

Iris and facial recognition
Facial recognition technology is increasingly being used at airports to identify and track travellers. This technology is often presented as a convenient way to speed up security processes and enhance security. However, there are growing concerns about the implications for privacy and civil liberties.
Facial recognition cameras are placed at TSA checkpoints in airports. When a traveller approaches, the camera takes a photo, which is then matched in real time to the photo on their passport or visa. This process is currently in use at over 80 airports in the US and is set to expand to over 400 federalized airports. Additionally, companies like CLEAR have implemented iris authentication software embedded in kiosks at more than 30 major US airports, allowing enrolled travellers to move through security much faster.
Privacy and Civil Liberties Concerns
The use of facial recognition and iris scanning raises serious privacy concerns. The data collected, including fingerprints, facial images, and iris scans, are stored in FBI and DHS databases. This data is then used for immigration, law enforcement, and intelligence checks, including unsolved crimes. There are risks of false matches and wrongful arrests, especially for immigrants, people of colour, women, and young people, as these groups are disproportionately represented in criminal and immigration databases and face recognition systems struggle to identify them accurately.
Opting Out
It is important to note that participating in facial recognition scanning at airports is optional. Travellers can choose to opt out and instead go through a manual identity verification process with a Transportation Security Officer. However, the opt-out option may not always be clearly communicated, and privacy experts recommend opting out to protect one's privacy.

Fingerprint scanning
The process involves collecting and scanning travellers' fingerprints, which are then compared to fingerprints stored in secure government databases. This allows officials to confirm the identity of the traveller and cross-reference this information with other databases to detect fraudulent entries or visa overstays. The U.S. Department of Homeland Security (DHS), for example, has been trialling and implementing the Biometric Entry Exit Program at U.S. Customs and Border Control (CBP) using the Traveller Verification System (TVS).
In addition to the U.S., countries like the United Arab Emirates and Saudi Arabia have established border security programs that require foreign travellers to provide fingerprints upon entry. This is done to enhance border security and identify potential security risks.
While fingerprint scanning has been a popular choice for biometric identification, some airports and governments are now favouring facial recognition technology. Facial recognition is considered quicker and more intuitive for travellers, as it does not require specific instructions or knowledge of how to use it. It also leverages existing photo databases, making it a more efficient choice.
Despite the benefits of fingerprint scanning, there are challenges to its implementation. These include low matching rates, infrastructure issues, and privacy concerns. As such, it is often used in conjunction with other biometric technologies or as a complementary measure to facial recognition verification.

Phone and electronic device searches
It is important to know your rights regarding phone and electronic device searches at airports. Many travelers mistakenly believe that Transportation Security Administration (TSA) agents can search their phones during security checks. However, only Customs and Border Protection (CBP) officers, not TSA agents, have the authority to inspect electronic devices, and only when you are entering a country, not departing. These searches are conducted by CBP at ports of entry, not by TSA officers at domestic checkpoints.
If you are a U.S. citizen, you cannot be denied entry for refusing to unlock your devices, but they may be temporarily confiscated. If you are a green card holder, you may face device confiscation and potential immigration consequences. As a visa holder, you may be denied entry and have your visa revoked. Only U.S. citizens have the right to legal representation at border inspections.
In addition to electronic device searches, TSA officers may request that you remove personal electronic devices larger than a cell phone, such as laptops, tablets, e-readers, and handheld game consoles, from your carry-on bag and place them into a separate bin for X-ray screening.
Airports are increasingly using new technologies to track passengers and gather information. Some of these technologies include full-body scanners, stereoscopic cameras, iris scanners, facial recognition technology, fingerprint scanning technology, and "screen-and-walk" technology to detect concealed devices. These technologies aim to improve security, reduce congestion, and enhance the overall airport experience.

CCTV and video monitoring
Airports are increasingly relying on CCTV and video monitoring to enhance security and operational efficiency. With a high volume of people and goods passing through, airports are vulnerable to various security threats, and these technologies provide a crucial layer of defence.
Strategic Deployment of Cameras
Surveillance cameras are strategically positioned throughout airports to capture all activities within and outside the location. Cameras are typically mounted at entrances and exits, check-in areas, security checkpoints, individual terminals, gates, corridors, and baggage claim areas. This comprehensive coverage enables the monitoring of passenger arrivals, activities, and tracking of suspicious behaviour or potential threats.
Advanced Video Analytics
The introduction of advanced video analytics has revolutionized airport security. Video analytics software, powered by artificial intelligence, enables the real-time detection and classification of objects, people, and events. This technology allows cameras to detect and identify individuals through facial recognition, cross-referencing them with databases of known offenders or suspects. It also facilitates the detection of abnormal behaviour, such as fights or individuals separated from their groups, allowing security personnel to respond promptly.
Enhanced Threat Detection and Prevention
Crowd Management and Safety
Advanced video surveillance systems aid in crowd management by monitoring crowd movement and density in real time. This helps in maintaining safety and preventing overcrowding situations. Video analytics can also assist in improving response times during emergencies by automatically detecting incidents and alerting security personnel, providing crucial information for swift and effective responses.
Commercial Applications
Beyond security, CCTV information is also used for commercial analysis. By monitoring footfall statistics, transit hub management teams can gain insights into visitor behaviour, such as their interactions with retailers, restaurants, and ad kiosks. This data informs tenant sales, pricing, and the valuation of terminal rental spaces. It also helps determine which amenities and attractions will positively influence the visitor experience.
