What is the principle of health code and how accurate can it be? Netizen: What about privacy?
What is the health code? I believe many friends know that there are two-dimensional codes in different colors, green, yellow and red, and each color has a different meaning.
The current health regulations are mainly formulated for COVID-19. You can judge whether you are healthy by three colors. First of all, you should report your health information, don't indulge in it, and seek truth from facts.
The reporting system gives you a QR code of health or not. If you conceal the truth, you may be infected with COVID-19 virus, so you should check your health. If you make a fake, you should be punished by law.
If you get the green code, but you go to the epidemic province, you may be infected, so the green code is changed to the yellow code. Isolation 14 days. If you want 1, you will be hospitalized with COVID-19, and the yellow code will be changed to red team.
If you have a small partner, you will ask. The reason is such a truth, so what is its working principle?
The data of health code comes from big data. For a simple example, the GPS location in the past 7~ 14 days, the location of offline code scanning merchants, the information of purchasing train tickets, etc. If you buy a train ticket to Hubei, the health code is likely to change color.
Health code is based on big data.
Health code is not a single existence, nor is it the personal declaration data you understand. At the end, anyone fills in the data, submits the data, and then analyzes it through a large number of databases in the background. At least, it depends on the records of where he has been recently, whether he has a record of hospital treatment, and declares the epidemic situation around him. Finally, the corresponding results are given.
Health codes will be used in more scenarios.
In order to better track a person's action track and understand his physical health. Imagine if a person can truthfully record this health code wherever he goes, and then analyze it through relevant background big data, can he accurately judge this person's situation? Of course, the term epidemic prevention and control is used at present, but it does not rule out that it will always exist as a necessary symbol in the future.
Health regulations need to improve relevant mechanisms.
Of course, although there is a strong background data analysis, it is also necessary for individuals to report the situation truthfully, so I believe that in a period of time, there will be relevant policies to make the health code healthier, the database more perfect and the travel safer.
Some netizens asked: I am concerned about whether the personal information you collected through health code registration will be abused after the outbreak in the future. !
In a word, the health code can't judge what's wrong with everyone. It can only track the trajectory of everyone's travel, and then use big data to give out whether it is possible to get in touch with COVID-19. The corresponding departments can be used as the basis for judgment, which is of great significance for epidemic prevention and control.
