How biometrics are changing airport security

With the development of the era of artificial intelligence, more and more biometric technologies are applied in the field of product security. Airport security inspection is to prevent passengers from carrying dangerous items such as flammable, explosive, corrosive and guns and ammunition to ensure the personal and property safety of aircraft and passengers.

Generally, it needs to go through three procedures, that is, whether the witnesses are unified, whether the body is safe, and whether the luggage is safe. With the development of science and technology, the airport security inspection technology has been continuously improved, and more new technologies have been applied, which has improved the security inspection efficiency and ensured the accuracy.
1. Whether the witnesses are unified
Proving your personal information is an important procedure, using relevant documents to prove if it is the same person, in the past, airports used manual checks to confirm the identity of each passenger, each passenger was identified by showing his/her photograph on the document And comparing photos on documents, however, it is sometimes difficult for employees to identify passengers due to the huge discrepancy between identifying photos and facial features, so security lines require the use of computerized ID information management systems and biometrics.
Biometric technology uses the unique physiological characteristics of the human body to identify, such as: Face Recognition Attendance, iris recognition, vein recognition, computer system algorithms to determine passenger ID cards, or check passenger lists. Now Face Recognition attendance systems are used in finance, education. , security and other fields, greatly improving the recognition accuracy and work efficiency.
2. Is your body safe?
Once identity is confirmed, the next step is to conduct a personal check through designated security lines to prevent the carrying of dangerous or contraband items. Currently, the main personal detection devices used at airports are metal detectors and security detectors. Metal detectors mainly detect various metal objects hidden in the human body, including jewelry, electronic components, etc.
3. Is your luggage safe?
When we go through the security check, the luggage must also be checked by an x-ray scan on the security screening machine. At present, the X-ray imaging technologies used in airports are mainly dual-energy X-ray imaging technology, multi-angle X-ray technology and CT-ray imaging technology.
Among them, compared with single-energy x-ray detection systems, dual-energy x-rays can obtain effective atomic number information and improve the material resolution capability of the system. CT technology can form three-dimensional images of objects, measure the thickness of materials, and distinguish explosives from other Similar substances with low atomic numbers.
With the wide configuration of airport x-ray security inspection machines, high-contrast materials such as knives and guns can be effectively investigated. Terrorists turned their attacks on explosives. Explosives are composed of low-contrast materials and are easily confused with ordinary items in luggage. X-ray CT technology has the highest detection accuracy, so it plays an increasingly important role in the field of security inspection.
