Security technology behind Beijing Winter Olympics

　　In the "Double Olympic City", there is such a team. They are at the beginning of their lives and bravely guaranteed the 2008 Summer Olympic Games. They strut and set off for the 2022 Winter Olympics and become a veritable "Double Olympic Team". This team is the "Double Olympic Covenant" electronic ticket team of 706 China Institute of Aerospace Science and Technology.

　　In the 2008 Beijing Olympic Games, people remembered the No.706 Institute of China Aerospace Science and Technology and their electronic ticket system. In this close contact between astronauts and the Olympic Games, the electronic ticket team of No.706 "Double Olympic Covenant" achieved "six firsts", which was something that previous Olympic Games wanted to do but failed to do: the first large-scale successful use of electronic chips and the deployment of inspection systems greatly improved the security of Olympic tickets; For the first time, electronic chips were embedded in Olympic tickets and certificates, which solved the problem of fake tickets and certificates in previous Olympic Games. For the first time, the real-name registration system was successfully implemented in the opening and closing ceremonies of the Olympic Games and Paralympic Games, ensuring the safety of the opening and closing ceremonies; For the first time, the authenticity of the ticket was successfully verified within 1/10 second, which ensured the rapid and smooth admission of nearly 10 million ticket holders in all events for nearly 5 million times; The real-time monitoring of admission information is realized for the first time, which provides timely and accurate decision-making basis for commanders at all levels to control the admission situation of each security checkpoint in real time, command accurately and respond quickly. For the first time, the automatic inspection and real-time control of lost tickets and certificates were successfully realized, ensuring the consistency of people, certificates and tickets and ensuring the safety of Olympic venues.

　　The electronic ticket system developed by 706 Institute was applied to the ticket inspection of the main venue of the 2008 Beijing Olympic Games.

　　Winter Olympics security is like an airbag. The smoother it is, the more hidden it is. If there is an order, it will be sharp. This team of only 40 people needs to complete tasks that others think are difficult to complete: from winning the bid for the Winter Olympics to the torch relay in the Winter Olympics, the team needs to complete tens of thousands of people’s certificates, including torch bearers, staff and on-site spectators, and thousands of train certificates in just 10 days, such as style design, logo design, data collection, data standardization processing, certificate making, human-centered association, certificate verification and multi-zone linkage. The work place of electronic ticket support for the torch relay of the Winter Olympics involves three competition areas, namely Beijing, Yanqing and Zhangjiakou, 11 closed transmission areas outside the closed loop and one independent transmission area inside the closed loop. The team needs to fully coordinate technicians and support personnel, and some members even need to travel all over the three competition areas within two days of the torch relay. The weather plays an extremely important role in the Winter Olympics. In order to ensure the smooth progress of the Winter Olympics, the team needs to ensure that the personnel and equipment keep working at a low temperature of MINUS 20 degrees … …

　　In 2008, Liu Lei, a volunteer for the Beijing Olympic Games, still used the electronic ticket system developed by 706 Institute of the Second Academy of Aerospace Science and Technology of China to check all the tickets of the spectators. By 2021, Liu Lei has become a member of the development team of the torch relay electronic ticket system for the Beijing Winter Olympics. Looking back 14 years ago, I was a beginner in the field of software engineering. Now, he has grown into a team technical leader who can lead the software development process. In the past 14 years, Liu Lei has never stopped studying, especially in recent years, when he took over the electronic ticket system, he devoted himself more desperately to this career he loved. Because he had used the ticket system, he often thought about the user experience from the user’s point of view and knew the pain points and shortcomings of the system. In the past, a lot of manpower and time were needed to standardize data processing and the link between people and chips after certificates were made. Liu Lei solved this problem perfectly by adding auxiliary processing programs to the software, which greatly reduced the manpower input and improved the production efficiency.
