Dr. Fang also found the other problem was that the computer data was not secure enough. At that time, a power-on password must be entered after the computer is turned on. After the password is passed, the computer can be used. However, the computer always gets a virus during use. Once a hacker cracks the power-on password, your computer data can easily be stolen. In order to secure the data of computer, Dr. Fang filed a patent application “Computer Data Protecting Method” in Taiwan, China, the United States, Japan, and India in 2004 and 2005, and all were certified.
This patent claims “password lock” . When a program is opened, even hackers wanted to secretly open certain files remotely, they would ask for another password, which is evolved into the APP Lock of smartphones. For example, to prevent private photos in the smartphone from being browsed, or prevent important data such as personal itinerary and notebooks from being stolen, we can set a “password” through the APP lock to lock any applications in advance. When the application is opened, you will be asked to enter the password. This is the password lock technology.

Dr. Fang is a science and technology genius. His firewall, cloud and password lock patents have created modern smart phones and brought indelible contributions to the development of human technology.  Smart phones with such advanced functions greatly improve the quality of life for the people in the world
