Health codes are based on actual data and can be generated by citizens or people who have returned to work through online declaration and background audit. As an individual entering and leaving electronic certificate locally, the QR code can be declared once, which is universal in the whole city. The introduction of the health code aims to make the work of returning to work more accurate, scientific and orderly.

I. Relevant standards

On March 5, 2020, the draft of the Reference Architecture and Technical Guide for Epidemic Prevention Passwords was reviewed by the expert review meeting and formally submitted for approval. The promulgation of this standard provides technical specifications for the development enterprises of epidemic prevention codes, and regulates and requires the functions required for personnel management, authorization management and collection point management of epidemic prevention code users.

On April 29, 2020, the General Administration of Market Supervision (Standards Committee) issued an announcement, releasing a series of national standards for personal health information codes. This series of standards adopted the quick procedure of national standards, and it only took 14 days from project establishment to publication. After the implementation of this series of national standards, the coding system, display mode and data content of personal health information codes can be unified, and the protection of personal information and the enjoyment and utilization of information can be considered as a whole, which is suitable for guiding the design, development and system integration of health code-related information systems.

On September 13, 2020, the National Health and Wellness Committee announced the Work Plan for Exploring the Special Services for the Prevention and Treatment of Alzheimer's Disease, requiring grass-roots institutions to regularly evaluate the cognitive function of the elderly; The National Health and Family Planning Commission announced its work plan, requiring grass-roots organizations to regularly evaluate the cognitive function of the elderly, and clearly put forward detailed tasks on how to do a good job in preventive services and targeted treatment of cognitive function diseases.

On June 5438+February 10, 2020, National Health Commission, the National Medical Insurance Bureau and state administration of traditional chinese medicine jointly issued the Notice on Further Promoting the Service Action of "Internet Plus Medical Health" and "Five Ones", explicitly requiring all localities to implement the national mutual recognition of "health codes" and communicate with each other. The Notice of Action requires that all localities should rely on the national integrated government service platform to implement the mutual recognition mechanism and rules of "health code" information, make it clear that the "health code" information of cross-regional floating population is credible and available in all regions, and effectively facilitate people's travel and inter-provincial mobility, so as to realize unified epidemic prevention policies, unified standards, national mutual recognition and one-code communication.

Second, the specific scope

The standard covers the functions closer to real life applications such as relatives binding, and solves the problems of reporting and traveling epidemic prevention information for the elderly and children.

The application scope of health code covers community management, resumption of business, transportation, starting school, drug purchase registration, supermarkets and shopping malls, which can help communities, enterprises and schools to do key work such as epidemic prevention management and epidemic control. In the prevention and control of epidemic situation and resumption of production, health code can realize efficient personnel flow management, improve the inspection efficiency of office buildings, shopping malls, subways, railway stations and other crowded places, and avoid excessive personnel contact and gathering.

Third, the main features

There are three kinds of "health codes": the green code can directly enter Hangzhou, the red code is isolated for 14 days, and the yellow code is isolated for less than 7 days.

The management information system of "health code" in Zhejiang Province is based on real data, connected with relevant databases such as the dynamic control list of key personnel, and distributes "health code" according to the results of checking and comparing the information declared by the masses with the background data.

The health coding system has formed a set of standards, which can be quickly introduced according to the needs of different regions and the needs of epidemic prevention and control in various places.

In order to promote the mutual recognition of "health code" in different places, the national comprehensive government service platform provides three ways to realize cross-provincial mutual recognition and sharing. The first way is to add the cross-regional mutual recognition function to the local "health code" through the cross-regional epidemic prevention and health information data sharing without changing the existing local "health code". Second, the local "health code" is connected with the national comprehensive government service platform "epidemic prevention information code", and the national comprehensive government service platform "epidemic prevention information code" is used as the intermediary to realize the mutual recognition of cross-regional "health code". Thirdly, in areas where there is no local "health code", the "epidemic prevention information code" of the national comprehensive government service platform can be directly adopted, and at the same time, combined with local epidemic prevention and health-related information, cross-regional interoperability and mutual recognition can be realized.

Through the health code, many health applications such as one-code medical treatment, appointment registration, one-click first aid, psychological assistance, health certificate, health file and so on have been realized.

From June 5438 to June 2022 10, Guangxi Zhuang Autonomous Region Big Data Development Bureau urgently expanded, optimized and upgraded Guangxi health code information system, and carried out independent innovation. On June 65438+ 10, 2022, it was the first to successfully develop and officially launch the "offline availability" function, ensuring that people can still travel with bright codes under extreme conditions such as health code system failure or even network interruption, and ensuring the safe and orderly flow of personnel. It is understood that this is the first available health code disconnection in China.
