For the leakage of personal privacy, it often triggers public panic, which will also become a major resistance to the development of the big data era. Therefore, it is imperative to protect privacy. However, protecting privacy does not mean that we should close ourselves off and reject the Internet, but we need to raise the awareness of privacy protection among citizens. What we can do is to minimize the leakage of privacy: reduce the use of positioning in the circle of friends, turn off the camera's own positioning, do not sweep the code of unknown origin? Remember not to sell your privacy for petty gains. Always remember that the protection of personal information privacy is to protect themselves.
