Health passwords include personal information, name, ID number and mobile phone number. People who are not trusted should try not to send health passwords to others. The green code page of the health code has encryption measures, and others have no right to view it. However, in order to prevent the green code date of birth from being tried out, it is not recommended to send it to others.
The health code is based on the actual data, which can be generated by citizens or people who have returned to work through their own online declaration, and then enter and leave the local electronic certificate as an individual after background audit.
