The face is aimed at a small screen at the security checkpoint of the airport. The security inspection equipment compares the obtained image with the ID card and can pass the confirmation without any mistake. Not long ago, the “China Science Journal” reporter experienced an airport at Chongqing Jiangbei Airport. Security intelligent identification system.
It is understood that the Chongqing Research Institute of the Chinese Academy of Sciences and Smart Aviation Security (Beijing) Technology Co., Ltd. have jointly developed this smart identification technology and verified the identity by comparing the registration of the ID card with the face of the on-site certificate holder. 99%, the verification speed is only 1 second. Recently, the project successfully passed the acceptance of the key special project (Hongguang special project) of the Chinese Academy of Sciences for transferring and transferring scientific and technological achievements.
'Black Tech' Creates Leading Recognition Technology
Shi Yu, the director of the Intelligent Security Technology Research Center of the Chongqing Research Institute of the Chinese Academy of Sciences, told reporters: “The airport security intelligent identification system has leading recognition technology with fast verification, high accuracy, and good adaptability to face angle, light, expression, and occlusion. . '
Before investing in industrialization, the team had done core technology research and development for a long time. Shi Yu likened the algorithm to the child's brain. 'Let a child be smart and have a wide range of knowledge. We let the computer's neural network learn more. Multiple data, extracted the concept of the model, which is somewhat similar to the concept of the human brain'.
Different from the '1: N' comparison method of the attendance system, this technique is to compare the ID photos with my own '1: 1', and a large amount of data difference models are needed for technical implementation.
Shi Yu introduced: 'In the earlier version, the intelligent identification system hardware only had one screen, and it only took a picture when the ID card was swiped. Compared with the ID card information through a single photo, the recognition speed was slow, and it was quite wrong. Passenger time. After summarizing the opinions of the civil aviation expert group and carrying out the system transformation, not only adds a passenger-oriented screen from the perspective of passenger experience, the system can also intercept passengers’ identity through more intelligent algorithms. Three seconds before the video card to do analysis, from which to obtain a higher quality, more conducive to the comparison of photos, so that one can compare the results, in the case of ensuring the recognition rate greatly improves the efficiency of the pass. '
On the basis of speed and precision, the intelligent identification system also achieves a compact appearance and convenient operation. The system adopts a modular design concept and can select single-screen or dual-screen devices according to the actual site environment, and can be equipped with different models of cameras or Card reader. Taking into account the actual situation of the airport, the research team added a tablet computer for operation at the front end, and made targeted optimization and improvement of the program, even if the disconnected network system can operate normally.
The application of the face recognition system effectively eliminates the illegal use of identity documents for over-examination, and can well cooperate with law and order, counter-terrorism and pursuit of flight, prevent boarding of controlled personnel, and enhance air-defence security at the airport. At the same time, security personnel are optimized. The work flow has effectively supported the construction of a multi-level, non-interfering, system-linked smart aviation security program, which has significantly improved the overall level of security inspection.
Combining technology with actual needs
The four key international airports in Chongqing, Beijing, Shanghai, and Changsha serve as the pilot fields for the first smart security identification systems. They have accumulated valuable practical experience for the R&D team. 'At that time, two or three channels were opened at each airport for trials. After one month of operation, the Civil Aviation Experts Group held an analysis meeting to recognize our products and hope to expand the area of use and assist them in formulating the corresponding process standards. Shi Yu said.
In early April 2017, the smart security identification system was installed in all the channels of the Chongqing Jiangbei Airport Terminal T2. Other cities are gradually promoting this technology. As of press time, the face recognition assistant verification system has been in 62 airports in China. 557 channels for demonstration applications.
Shi Yu told reporters that the process from the laboratory to the airport is not always going smoothly. 'As a research institution, we are not very good at industrialization. For example, more and more airports are using products, we cannot With more manpower and resources to deal with on-site installations, technical support, etc., funds for large-scale landing trials are also scarce. 'He said.
In the face of this dilemma, Chongqing Research Institute chose to cooperate with Smart Aviation (Beijing) Technology Co., Ltd. to jointly develop technology research and development, and on the other hand to use the latter's product experience and operational experience to better realize the products of scientific research achievements. In the meantime, the Hongguang Special Project of the Chinese Academy of Sciences also provided the team with strong research funding support.
Due to the special nature of security inspections, the airport will test and compare every new technology introduced. In May 2017, Guangzhou Baiyun Airport launched a large-scale 'PK' of intelligent identification technology to conduct on-site testing of four vendors. Home is a market-oriented company, but in the 50-day test, we have the best results. ' Shi Yu said.
In addition to airport security, smart face recognition technology has also been applied to the check-up verification system for the Nanjing Massacre in March 2017. R&D personnel store staff information in the check-in system, and the system can automatically identify identities, effectively avoiding The phenomenon of an impostor's name was praised and appreciated by the leading group of the public security ceremony.
Continue to accelerate the demonstration application
As a newly-established institute that has been officially running for only more than three years, the Chongqing Research Institute’s face recognition assistant verification system has been included in the report of the 2018 annual work conference of the Chinese Academy of Sciences. It was recognized as a key core technology for the transformation and upgrading of related industries, and for the economic and social Development, scientific and technological progress and national security have made significant contributions to the representative achievements '.
On January 29, 2018, a representative of the ICAO 14 National Council visited and inspected the Civil Aviation Anti-Terrorism Technology Joint Laboratory, and prepared to write face recognition products on the ICAO product list.
Shi Yu said: “Implementing intelligent identification of security inspections in a multi-ethnic passenger environment is an important research direction and goal of this project. In addition, with the assistance of the Innovation Cooperation Center of the Chinese Academy of Sciences in Bangkok, the Chongqing Research Institute has started technology docking with the Bangkok International Airport. Facing the country's 'One Belt and One Road' initiative, it exports advanced face recognition technology and products.
At present, the research team is advancing the standard-setting work on face recognition application technology in civil aviation safety inspections, and speeding up the implementation of the construction of the portrait data center and test platform. In the future, the country’s first 100 million-person portrait data center and tens of millions of people face recognition. The birth of the test platform will not only provide powerful data support for technological upgrading, but also provide the necessary data basis for the development of human face recognition security and common technologies in national public security, transportation, and finance.
Shi Yu said that in addition to standard setting and platform construction, the team is also developing a full-process paperless face recognition clearance system—this is a passenger identification and review, intelligent security inspection delivery, dynamic face recognition, channel monitoring, and dispatching. Information management, self-service customs clearance crossing, airport staff management integrated security information management system, is expected to be put into use at the airport in June and July of this year.
According to the airport requirements, the Chongqing Institute will also gradually promote the work status management of the X-ray security inspection machines, automatic inspection of X-ray security inspection machines, control of people and vehicles in key areas, and development and demonstration applications of airport perimeter protection systems. These technologies will To provide a full range of security for the airport, the actual value and market potential is very large.
