The data is given by 250 identification points, but the speed is slightly slower and is generally used for re-examination of suspicious passengers. Face recognition can achieve an accuracy of 80% to 90%, but it is affected by factors such as camera angle, illumination, and age. The biggest difficulty is that while getting lost and receiving people will find it helpful, tracking the violations of individual privacy by individual will make it encounter strong resistance.
Passengers' luggage and belongings are also tagged with a radio frequency identification (RFID) so that they can be located at any time. The tag also corresponds to the smart card, and there is no case where the passenger is not boarding and his baggage is on the plane. The baggage check will also apply a laser scanner, and after finding suspicious baggage, find and block the owner of the bag immediately.
Second level: manual monitoring
To handle complex situations flexibly and flexibly, security experts at airport command centers and police officers located throughout the airport are still essential.
Third pass: passenger safety scan
If the most stringent precautions are taken, the future security door will be a corridor made of bulletproof glass that can be locked at both ends. After the passenger swipes the smart card, the face is scanned again, the identity is verified, and the personal items and clothing are also checked by a laser scanner, which replaces the X-ray inspection and the metal detector. The biggest shortcoming of X-ray examination is that you can see the body under the clothes, similar to the perspective function of digital cameras. Although the United States has developed image processing software that intentionally ignores gender characteristics, there are still many passengers and human rights organizations who are strongly dissatisfied.
Fourth pass: boarding gate
Passengers boarding also rely on smart cards. If problems are found, such as unchecked personal belongings, the boarding gate will be closed and passengers will be investigated.
Fifth level: the aircraft and its surroundings
All airport employees are also required to perform facial or iris scans to confirm their identity when they go to work. Laser scanning is used to check for explosives or weapons. Employees must wear special RFID badges to enter special areas. The camera monitors around the airport, and image processing software can distinguish between curious dogs or deliberate intrusions. The aircraft is monitored by digital cameras that are triggered by the motion of the monitored object, as long as there are any unauthorized activities in the cargo door, landing gear bay and engine. Hide the camera in the cockpit, cabin and aisle and send it to the ground
The idea of returning to the real-time image is also under discussion, of course, at the expense of personal freedom.
