In our daily life, we may find that when we want to buy something, we will habitually search in a treasure first. At that time, we searched on the computer, browsed several products and passed. But when we browse the headlines of mobile phones at night, advertisements for something are constantly pushed to my mobile phone, which is really scary. The attention of information searched on the computer has been quickly transmitted to the mobile phone. There seems to be no personal privacy in the era of big data. In the face of big data, people don't know it, but big data has seen people through!

Although the rapid development of the Internet and the coming era of 5G coverage for all people need a smart phone to complete the tedious work before, similarly, our every move, likes and dislikes, can also be collected and monitored by a mobile phone. First, if you have a smart phone, you need to install several app applications. Therefore, before opening the application, the application requires us to give certain permissions. For example, the application will ask us to open the location permission, or read the information and pictures of the mobile phone, or read the permission of the application we installed, and some even ask for access to our contacts. Many applications will record our running track, and we will record how many steps we have taken. The service is really thoughtful!

There are inevitable privacy leaks in life, such as. We need to fill in our name, mobile phone number, email address, etc. When registering the website. If you need real-name authentication, you also need to fill in the ID number. Some websites even require face recognition, and the collected information will be stored in? Cloud? , and euphemistically called? Big data? . This information is very important to us, and it is enough only if it is preserved. If some unscrupulous merchants package and sell, we are undoubtedly in the information age? Streaking? No privacy at all.

In the era of big data, everyone is almost transparent, so how to protect personal information from infringement is the most important issue now.
