Wang Hui: Efficiency, Security Or Equality?

You don't need to take off your coat, do not open your hand luggage, and do not need to be embarrassed to be searched. It takes only five or six seconds to go through a classified security channel, and you can successfully complete the airport security check. The security check process may even be carried out step by step with customs clearance procedures. Recently, the International Air Transport Association announced for the first time this "future airport security station". Idea The embryonic form has aroused many people's interest and interest.

According to this concept, passengers carrying out security inspection will be divided into three categories: identified passengers, general passengers and key security passengers. The airport security will be based on biometric information in passports or other travel documents, and the government's action on it will be carried out. risk assessment As a result, classification is done ahead of time. When passengers arrive at the airport security station, different levels of security measures are implemented according to their different risk categories. "Identified passengers", that is, registered and certified by the competent authorities of the government, can enjoy fast security inspection, while "key security passengers" need to be screened through additional screening technology.

In the current mode of security inspection, almost all articles carried by passengers must be checked. This method has been designed and used for more than 40 years. The core idea of the "future airport security station" is to turn dangerous objects into dangerous ones. Through statistical passenger's "risk coefficient", it focuses on solving small probability events with high risk coefficients and maximizes the throughput of most low-risk passengers.

The change of this concept is related to international aviation in recent years. Security situation Development is inseparable. The situation in West Asia and North Africa continues to be turbulent, and the terrorist attacks are impossible to prevent. According to the International Air Transport Association (IATA) statistics, the global aviation industry will spend $7 billion 400 million a year on security. Passengers' travel experience is also getting worse and worse. Especially in some European and American countries, long queuing, baggage being unpacked, and human being's "perspective" make travel by air less pleasant and respectable. Terrorists are only a handful, but most of them sacrifice their personal privacy and bear time cost, which makes the aviation industry bear additional security costs, which is unreasonable and uneconomical. Because of this, the future airport security station will focus its attention on people. According to the International Air Transport Association, 18 countries including the United States are setting up the "future airport security station" standard. Some progress has been made in the technology of biometrics screening and passenger classification conversion. In the near future, the "future airport security station" will probably appear in front of the passengers.

However, any means of security inspection will be limited. The development of the future airport security station will also face many problems: whether the biometrics technology is reliable, whether the standards of passenger risk coefficient are uniform or not, how to achieve information sharing among different airports, and so on, are all urgent problems to be solved. More importantly, human factors are complex and changing. Just imagine that the travellers without criminal record may become dangerous objects, or their luggage is being handled by others. It is also a dishonorable thing to be taken out of the traveling group by the passengers who are assigned to the key objects, and it may also cause objective discrimination on the basis of the formulation and implementation of standards. The concept and technology renewal of safety inspection is worth trying, but it can not solve the problem thoroughly. In order to be efficient, safe or equal, the contradiction will continue in a new form.
