In today's digital era, the rapid development of information technology has made the network closely connected with people's lives. While various network services provide convenience to users, they have also caused serious problems in user personal information security. The security of personal information not only causes serious infringement on personal rights and interests, but may also have a negative impact on corporate reputation, social stability and national security. In the network environment, strengthening the security protection of user personal information has become an urgent task. This article aims to deeply analyze the current situation, problems and internal laws of user personal information security protection, and conduct comprehensive and systematic visual analysis of relevant data through network metrology methods, thereby providing solid theoretical basis and practical and feasible suggestions for building a more complete user personal information security protection system.
