The most important part of health code is mobile phone location based on mobile phone number, consumption record, travel and plane record based on ID number, filling in travel information or scanning scene location registration, etc. , and combined with the epidemic situation, big data analysis shows the results.
All kinds of health codes are basically docked "communication big data travel cards", which are not restricted by regions and do not collect ID numbers and home addresses. As long as you enter the mobile phone number, you can get the travel information of the past 14 days according to the communication network data. The principle is that the location of the user's mobile phone can be effectively located based on the mobile phone signaling data, so as to find the owner himself.
The health code is based on the actual real data, which can be generated by citizens or people who have returned to work on their own 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.
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 "Five Ones" Service Action of "Internet+Medical Health", explicitly requiring all localities to implement the national mutual recognition of "health codes" and communicate one code.
