After the September 11 attacks, there was an immediate call to action regarding the state of aviation security measures as the hijackers involved in 9/11 were able to successfully pass through security and take command of the plane. The existing security measures flagged more than half of the 19 hijackers in 9/11; however, they were cleared to board the plane because their bags were not found to contain any explosives. In the months and years following September 11, 2001, security at many airports worldwide were reformed to deter similar terrorist plots.
The Transportation Security Administration (TSA) is an agency of the United States Department of Homeland Security (DHS) that has authority over the security of transportation systems within, and connecting to, the United States. It was created as a response to the September 11 attacks to improve airport security procedures and consolidate air travel security under a combined federal law enforcement and regulatory agency.
Airport security includes the techniques and methods used in an attempt to protect passengers, staff, aircraft, and airport property from malicious harm, crime, terrorism, and other threats.
Iris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of one or both of the irises of an individual's eyes, whose complex patterns are unique, stable, and can be seen from some distance. The discriminating powers of all biometric technologies depend on the amount of entropy they are able to encode and use in matching. Iris recognition is exceptional in this regard, enabling the avoidance of "collisions" even in cross-comparisons across massive populations. Its major limitation is that image acquisition from distances greater than a meter or two, or without cooperation, can be very difficult. However, the technology is in development and iris recognition can be accomplished from even up to 10 meters away or in a live camera feed.
The Computer-Assisted Passenger Prescreening System (CAPPS) is a counter-terrorism system in place in the United States air travel industry that matches passenger information with other data sources. The United States Transportation Security Administration (TSA) maintains a watchlist, pursuant to 49 USC § 114 (h)(2), of "individuals known to pose, or suspected of posing, a risk of air piracy or terrorism or a threat to airline or passenger safety." The list is used to pre-emptively identify terrorists attempting to buy airline tickets or board aircraft traveling in the United States, and to mitigate perceived threats.
A registered traveler is a person qualified through an airline passenger security assessment system in the United States air travel industry. Such programs were initially tested in 2005. Registered traveler programs are currently in operation in various airports around the country and are administered by TTAC, the Transportation Security Administration (TSA) office responsible for Secure Flight, the replacement for the Computer Assisted Passenger Prescreening System (CAPPS) and the canceled CAPPS II counter-terrorism system.
Security theater is the practice of implementing security measures that are considered to provide the feeling of improved security while doing little or nothing to achieve it.
A boarding pass or boarding card is a document provided by an airline during airport check-in, giving a passenger permission to enter the restricted area of an airport and to board the airplane for a particular flight. At a minimum, it identifies the passenger, the flight number, the date, and scheduled time for departure. A boarding pass may also indicate details of the perks a passenger is entitled to and is thus presented at the entrance of such facilities to show eligibility.
SmartGate is an automated self-service border control system operated by the Australian Border Force and New Zealand Customs Service and located at immigration checkpoints in departure and arrival halls in ten Australian international airports, and 4 New Zealand international airports. SmartGates allow Australian ePassport holders and ePassport holders of a number of other countries to clear immigration controls more rapidly, and to enhance travel security by performing passport control checks electronically.
Secondary Security Screening Selection or Secondary Security Screening Selectee, known by its initials SSSS, is an airport security measure in the United States which selects passengers for additional inspection. People from certain countries are subject to it by default. The passengers may be known as Selectee, Automatic Selectee or the Selectee list. The size and contents of the list fluctuates and is a secret, although the Transportation Security Administration has stated there are tens of thousands of names on it.
A full-body scanner is a device that detects objects on or inside a person's body for security screening purposes, without physically removing clothes or making physical contact. Unlike metal detectors, full-body scanners can detect non-metal objects, which became an increasing concern after various airliner bombing attempts in the 2000s. Some scanners can also detect swallowed items or items hidden in the body cavities of a person. Starting in 2007, full-body scanners started supplementing metal detectors at airports and train stations in many countries.
Daon is an international biometrics and identity assurance software company founded in 1999 by Irish entrepreneur Dermot Desmond. The name, Daon, was chosen because it stems from the Celtic word for human being, duine daonna. Daon is headquartered just miles outside of Washington, DC in Fairfax, VA. Daon also has major operations in Dublin, located in the International Financial Services Center (IFSC). It has an additional offices in Belgrade, Serbia and Canberra, Australia.

The company offers a cloud-based and open-architected anti-fraud platform and is historically known for its multi-factor authentication and electronic signature software.
Automated border control systems (ABC) or eGates are automated self-service barriers which use data stored in a chip in biometric passports along with a photo or fingerprint taken at the time of entering the eGates to verify the passport holder's identity. Travellers undergo biometric verification using facial or iris recognition, fingerprints, or a combination of modalities. After the identification process is complete and the passport holder's identity is verified, a physical barrier such as a gate or turnstile opens to permit passage. If the passport holder's identification is not verified or if the system malfunctions, then the gate or turnstile does not open and an immigration officer will meet the person. E-gates came about in the early 2000s as an automated method of reading the then-newly ICAO mandated e-passports.
Airport privacy involves the right of personal privacy for passengers when it comes to screening procedures, surveillance, and personal data being stored at airports. This practice intertwines airport security measures and privacy specifically the advancement of security measures following the 9/11 attacks in the United States and other global terrorist attacks. Several terrorist attacks, such as 9/11, have led airports all over the world to look to the advancement of new technology such as body and baggage screening, detection dogs, facial recognition, and the use of biometrics in electronic passports. Amidst the introduction of new technology and security measures in airports and the growing rates of travelers there has been a rise of risk and concern in privacy.
TSA PreCheck is a Trusted Traveler program initiated in December 2013 and administered by the U.S. Transportation Security Administration that allows selected members of select frequent flyer programs, members of Global Entry, Free and Secure Trade, NEXUS, and SENTRI, members of the US military, and cadets and midshipmen of the United States service academies to receive expedited screening for domestic and select international itineraries.
