Method and device for unlocking

[0093] based on figure 1 In the mobile terminal shown, in order to realize an unlocking method with high security performance, this embodiment adds some functional modules to the mobile terminal 100 to form an unlocking device 100', as shown in image 3 shown, including:

[0094] The password setting unit 310 is used to set and store the original password; the original password can be a pure number password, a pure letter password, a combination password of numbers and letters, or a combination password of numbers, letters and special characters, and the length of the password is not limited. In this embodiment, the password setting unit 310 is specifically a direct setting unit, which sets and stores the original password by directly inputting characters or selecting characters through a soft dial.

[0095] The dynamic keyboard display unit 320 is used for displaying a dynamic keyboard on the touch screen when the device enters the waiting state, and the distribution of each ke

[0117] Example 1: Suppose the original password preset by the user is 123456; after the device enters the unlocking state, the dynamic keyboard displayed on the touch screen is as follows: Figure 5 shown.

[0118] Then, the graphic drawing method of unlocking the password this time is as follows: Figure 5 Shown: Connect the numeric characters 1, 2, 3, 4, 5, and 6 that make up the preset original password in sequence, thus forming a Figure 6 The graphic shown is used as the unlock password for this time.

[0119] Example 2: Suppose the original password preset by the user is 137569; after the device enters the waiting state, the dynamic keyboard displayed on the touch screen is as follows: Figure 7 shown.

[0120] Then, the graphic drawing method of unlocking the password this time is as follows: Figure 7 Shown: Connect the digits 1, 3, 7, 5, 6, and 9 that make up the preset original password in turn to form a password such as Figure 8 The zigzag shown is used as the unlock password this time.

[0121] In this example, if the graphic entered by the user is also Z-shaped, but the input is not standardized and the error exceeds the preset error threshold, for example, it is recognized as a short Z, then the unlocking is unsuccessful.
