On February 7, 2020/KLOC-0, the Office of the Leading Group for Epidemic Prevention and Control of Hangzhou issued "On the opening of public places and public transportation in the city?" Hangzhou health code? Scan code authentication function notification requires the use of health code authentication in public places such as buses and subways. According to the contents of the notice, I tried to understand how it prevented and controlled the epidemic.
First, an official QR code will be provided, and Alipay will scan into the authorization interface. At this time, authorization is needed, and then Alipay will jump to a real-name authentication? Hangzhou health code? Interface: In this interface, there will be the name, certificate type, certificate number, mobile phone number, whether you are in Hangzhou at present, current address details, whether you left Hangzhou in the last 14 day, whether you have been in contact with a confirmed patient or suspected patient in COVID-19 in the last 14 day, current health status and my commitment.
According to the individual's actual situation, after filling in the information truthfully and submitting it to the background, the most important first step of tricolor coding is completed: data acquisition.
After the data collection is completed, the data will be analyzed through the background, and whether the filled location information is consistent with the positioning obtained by the mobile phone, whether it is consistent with the personal information of real-name authentication, whether it is a potential crowd who has been in contact with patients in COVID-19 for 14 days, whether there is any physical abnormality, whether there is an epidemic in the travel area, whether it is necessary to isolate, etc.
Through the analysis of background data, the authentication tricolor code is given. The green code is accessible, the yellow code needs to be quarantined for 7 days, and red team needs to be quarantined for 14 days.
This is the second step of three-color coding: personal data analysis and health certification.
Of course, because the information I certified is healthy, I can't know it for the time being. If it is yellow or red, whether to send the data to the background and provide it to the office of the leading group for epidemic prevention and control in Hangzhou for medical isolation. But I believe that such measures should exist, and only in this way can we really and effectively prevent and control the epidemic.
This is also the last step of tricolor coding: joint prevention and control, timely control and isolation of yellow and red high-risk groups to avoid the spread of the epidemic.
