Problems solved by technology

Among them, when in public places with a large flow of people such as subways, cafes, buses, shopping malls, etc., users will inevitably need to check some private information or account information, but people pass by from time to time, so it is easy for others to peek at their own Privacy, if you encounter criminals, it will cause economic or privacy damage to the user. At this time, the user has to turn off the screen of the mobile phone when others pass by, and then turn on the screen again. However, this operation is troublesome and time-consuming, which affects the normal operation of the user. use

Abstract

The invention discloses a fingerprint-based dynamic display method and a device. The method comprises the following steps: when a signal for pressing a fingerprint button for a long time is received, the entire display interface of the current terminal screen becomes fuzzy; whether a touch body touches the display interface of the current terminal screen is detected; if the touch body touches the display interface of the current terminal screen, the display interface area touched by the touch body restores to be clear. A one-key fuzzy function can be realized on the display interface of the terminal screen, when the fingerprint button is pressed for a long time, the user can select an area which needs to be restored to be clear in a touch mode, the remaining areas keep fuzzy, the operation is simple, privacy can be prevented from being seen by other people, good privacy protection is provided for the user, and continuous use of the terminal by the user is not influenced.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and more specifically, to a fingerprint-based dynamic display method and device. Background technique [0002] With the development of science and technology, mobile terminals have become an integral part of people's lives, and more and more people use these smart devices to communicate and connect. [0003] The current mobile terminal contains a large amount of information, such as private information, account information, etc., which makes the security of the mobile terminal particularly important. Among them, when in public places with a large flow of people such as subways, cafes, buses, shopping malls, etc., users will inevitably need to check some private information or account information, but people pass by from time to time, so it is easy for others to peek at their own Privacy, if you encounter criminals, it will cause economic or privacy damage to the user. At this ti...
