In the Internet age, the popularization of terminal devices, led by smart phones, has completely digitized people's social life. People spend more and more time on social networking every day, and the amount of data generated continues to grow accordingly. According to IDC's "Data Age 2025" report, the annual data generated globally will increase from 33ZB in 2018 to 175ZB, which is equivalent to 491EB of data generated every day. We are in an era of big data. A large amount of data involving personal privacy, property information and behavior trajectory is stored and transmitted on the Internet every day. The importance of protecting data security is self-evident.

However, in recent years, large-scale data breaches have emerged one after another, which has continuously aroused concerns about network security from all walks of life.

In 2019, Comparitech's security officer Bob Diachenko released a report saying that he found more than 267 million Facebook user IDs, names and phone numbers in a database that appeared on the Internet.
