Embodiment 1
[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...
example 1
[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.
example 2
[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.

Abstract
The invention provides a method for unlocking and a device for unlocking, wherein the method for unlocking comprises the following steps: presetting an original code and storing it. When a device enters a to-be-unlocked state, displaying a dynamic keyboard with changed key position distribution at random on a touch screen; automatically drawing a picture as an unlocking code this time according to the original code and the current displayed dynamic keyboard; after the device enters the to-be-unlocked state, detecting the picture drawn on the touch screen through touching in real time; when the picture drawn on the touch screen by touching is detected, judging if the detected picture at present is matched with the picture of the unlock code this time; if matched, unlocking the touch screen. The original code is transformed to be the unlocked picture; in the process of unlocking, a user can unlock only by drawing the unlocking picture according to the key position of the current dynamic keyboard distributed at any one position on the touch screen; thus the risk of original code leakage is greatly reduced, the safety is improved; moreover, the user can conveniently operate the method and the device.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an unlocking method and device. Background technique [0002] Most electronic devices such as mobile phones, digital cameras, and tablet computers store personal privacy. When the electronic device is not used for a long time, the screen lock will be activated when it is turned on again to prevent unauthorized use by others, thereby achieving the goal of protecting personal privacy. Purpose. At present, the methods for entering passwords on the touch screen mainly include: virtual keyboard input number unlocking, soft dial selection number unlocking, and pattern unlocking. When using the virtual keyboard to input numbers to unlock, when the position of the number keys is fixed, it is easy for others to decipher the password through finger marks; It is inconvenient; when using the soft dial to select the number to unlock, because the password length is fixed, it i...
