Embodiment Construction

[0018] This embodiment provides a password protection method based on a touch screen. The method detects the number of areas touched by a user on the touch screen as a password input. see figure 1 , the password protection method includes the following steps:

[0019] Step S101, using a multi-point touch screen to sense a user's touch operation.

[0020] Step S103 , detecting the number of mutually separated touch areas included in the touch operation. Such as detecting how many fingers of the user are in contact with the touch screen at the same time. see figure 2 and image 3 , which are schematic diagrams of the operation of the password protection method based on the touch screen, respectively, figure 2 It means that the user touches the touch screen 20 with one finger, and at this time, only one touch area 210 is detected for the touch operation. image 3 It means that the user touches the touch screen 20 with two fingers, and at this time it will be detected that...
