One code transmission refers to the health code under the epidemic situation. Based on personal health data, it is a personal QR code generated by comparing personal declaration with background big data information, which helps people to flow safely and orderly across provinces and return to work normally.
One code pass is a personal QR code generated by comparing personal declaration with background big data information based on personal health data. Every time a citizen scans the code, personal identification information, such as ID number, name and nucleic acid test results, will be displayed on the health code. Risk level information, such as red team indicates high risk, yellow code indicates medium risk, and green code indicates low risk or no risk.
One code communication information comes from data collected by the state. After prevention and control rules, data modeling and background comparison, three COVID-19 risk levels are judged and displayed in three colors: green, yellow and red. ?
After individual application, if it is a confirmed, suspected or asymptomatic case, the system will automatically issue a red team. The system compares the health code application of close contacts or individuals, reports it as unhealthy, and the system will automatically issue a yellow code. System comparison does not belong to the "five categories of personnel" (confirmed, suspected, asymptomatic, close contact, fever), and will automatically issue a green code.
Health code is strictly controlled from the aspects of network, application and data mode, and personal information is strictly encrypted and desensitized. The staff can only obtain the color and inspection information of the health code by scanning the code, and the design of the code scanning function fully considers the protection of personal privacy.
