In recent years, the security of domestic airports has become more and more stringent, and most people who often fly by the plane are suffering from airport security. In the Middle East, Israel’s Ben Gurion Airport, one of the most dangerous airports in the world, has the most concise and civilized security system in the world . This method of combining with high-tech lie detectors has been adopted since more than 40 years ago, and there have been no hijackings or explosions on flights departing from this airport.
New Breakthrough: Misantagonism
Israelis refer to this type of security inspection as "analysis of behavior patterns." "Discovering a possible terrorist is much more effective than trying to find his bomb." An Israeli senior official said, "The '9.11' hijackers killed 3,000 people without using real weapons or explosives. For your own sake, you have to stop those who are ill-intentioned. This is how our system works."
Rafi Serra, Israel's top security consultant, called the technology "Trust Based Security," or TBS for short. According to Rafi Serra, unless any truly effective inspection measures are taken, the use of any technical means will not help. Terrorists will always be one step ahead of you. Therefore, the efficient and accurate "behavioral pattern analysis" system is more like the trend of security inspection in the future than focusing on the inspection of hazardous materials.
The starting analysis of “behavioral model analysis†even goes beyond the airport: passengers who pay cash to purchase one-way tickets at airport ticket offices are more likely to attract the attention of security personnel than those who use credit cards to purchase return tickets through the Internet. The physical layer of this inspection program was even placed a few kilometers away from the departure hall: there are checkpoints on the only road to the airport for cars. The British "Daily Mail" reporter has repeatedly entered and exited Ben Gurion Airport, but he was stopped and checked every time - obviously because he did not take a taxi but sat in an Arab friend. Some of the old private cars.
In fact, the most critical elements of the system are young agents who correspond to the "selector" of security systems. In most cases, their problems will not occupy passengers for a lot of time, and passengers who pass the check will soon arrive at the boarding gate. But sometimes, the suspicious diseases of these “selectors†can also occur, especially when meeting some inexplicable tourists or those who claim to come to Israel but cannot remember what they have seen. Such travelers will face more sharp questions and their luggage will be thoroughly searched. If he still cannot provide a satisfactory answer, he will be detained in a single room and an experienced investigator will conduct the interrogation.
"Hostile Detector" Improves Efficiency
In the past, this system was mainly maintained by manpower. Agents responsible for security inspections asked the passengers many questions every day. Now, using the machine can automatically complete this inspection, greatly improving the speed of security .
Studies have shown that everyone follows the simple pattern on the screen to trace a unique zigzag pattern. This recognition system is much safer than a typical fingerprint or iris recognition system. The new identity system is based on people's eye movement reaction to moving objects on the screen.
The hostile detection device derived from the eye movement reaction device can simultaneously measure up to 14 parameters such as the temperature, heart rate, sweating, blood pressure, and respiratory changes of the subject's skin. When the equipment started to work, in order to set a "biological baseline", all these readings were almost instantaneously collected. In the next 30 seconds, the machine will display a stimulus theme that responds to those who are involved in terrorism, and ordinary people do not respond to this topic.
Related tests have shown that in the event that inspections have to be carried out, this system can be used to inspect passengers at any airport and will not slow down the pre-boarding inspection process. Compared with the common security check, in this system, passengers do not need to undergo a full-body scan, and do not need to go through the cumbersome screening steps. They only need to scan the eyes of the receiving machine and confirm that they are correct before boarding. In Israel, security personnel work on average for more than 10 hours a day. If this system is used, it will greatly increase work efficiency and allow security personnel to concentrate on improving professional skills in hazard screening and psychological identification.
Suspected passenger receives "physiological scan"
The hostile detection device can be used without interrupting the normal flow of people at the airport. It does not require human trials and does not violate human rights. Passengers who have been detected by the hostile detection device with higher suspicions will be transferred to the "Automatic Physiological Recorder" office. This kind of airport equipment based on question-and-answer detection technology is essentially a variety of wave biographers that automatically scans and records the pulse rate and respiration rate. This device includes a cubicle where passengers can sit inside and then put on headphones to answer questions. Problems are read out on the screen while they are on the phone. The passenger puts his left hand in a special stand and the sensor reads and records a series of data from the skin conductivity to the skin movement from the passenger's eyes and left hand.
The testing instrument is based on the body's physiological response to these issues, and gathers all the information collected and performs statistical analysis through computer algorithms. Most subject information will be deleted after 1 minute, and very few people will be asked to continue answering more questions, which will last 5 minutes to 7 minutes. Subsequently, the machine will determine whether the subject's information is cleared or continue to be subject to manual interrogation.
Questionnaire-based detection technology detects the environment more privately, and it is more like a “naked†scan of the passenger’s brain and a deeper touch on the idea than a “naked†scan and deep-seated physical security. The difference is that it does not infringe on the privacy of the traveler's body, and there is no need to worry about the leakage of private information.
Trace Detection Check Baggage Cargo
There are many more innovative technologies in the new TBS system, such as "trace detection" equipment. This device can detect the explosive powder contained in all types of sealed bags, whether it is hand luggage or cargo containers, passengers do not even have to take out laptops or other equipment for inspection. While the baggage is passing through the machine, the analysis results can come out. It is said that this device can detect as little as 1 microgram of known explosives, and neutron detectors used to scan explosives can only find 0.1 grams of explosives at this stage. This technology has also enhanced security while speeding up airport security inspections.
If necessary, this security system can be run from the database of the security service network. Through a hidden software platform, airports and other agencies can conduct global real-time contact through smart computers or police station networks.
There is a hidden “positioning system†in this security system at Ben Gurion Airport that allows the airport to locate and locate a passenger, or suddenly reminds staff to be alert. Researchers have developed a computer chip that is extremely low-cost and barely visible to the naked eye and can be used in boarding passes, employee identification cards, and baggage tags. They respond to the sensors immediately, and the sensors can be hidden into every gap, floor, or floor corridor. This way, operators can always know where each person is located.
