[0005] (3) Enter the password to unlock, which is divided into two types: simple password unlock and complex password unlock. The simple password is 10 digits to choose, and the complex password is selected by the user based on the full keyboard, such as Apple users or Android users often use The simple password is a 4-digit PIN code (the password of the SIM card), and the number array when unlocking is as follows: figure 1 As shown in (a), the user only needs to select the corresponding number. The operation is simple and easy, and it also has a certain degree of confidentiality, but it is easy to leak the unlock password through gestures during input.
Although complex passwords are more secure, users usually need to frequently lock and unlock the mobile phone, and unlocking complex passwords will inevitably increase the complexity of user operations.

Embodiment 1

[0054] Embodiment 1. The mobile phone receives user operation instructions to light up the mobile phone screen; automatically generates an unlock interface including a random number array of ten numbers from 0-9. Such as figure 1 shown, where figure 1 The picture in (b) shows the situation of the unlocking interface of the random number array generated during the nth unlocking, figure 1The picture in (c) shows the unlocking interface of the random number array generated during the n+1th unlocking. It can be seen that the unlocking interface of the random number array generated during each unlocking of the present invention is different, so other people cannot use it from The user's unlock password can be deduced from the user's gestures or touch traces left on the mobile phone screen when unlocking, which improves the security of the password.

Embodiment 2

[0055] Embodiment 2, the mobile phone receives user operation instructions to light up the mobile phone screen; automatically generates a random number array unlocking interface including ten numbers from 0-9 and symbols * and symbols #. Such as image 3 shown. in, image 3 The picture in (a) shows the situation of unlocking the interface with the random number array generated when unlocking for the nth time. image 3 The picture in (b) shows the situation of unlocking the interface with the random number array generated during the n+1th unlocking.

Embodiment 3

[0056] Embodiment 3, the mobile phone receives user operation instructions to light up the mobile phone screen; automatically generates a random number array including any 9 numbers in the number 0-9, forms a nine-square grid, and enters the unlocking interface. better, such as Figure 4 As shown, a nine-square grid containing 9 numbers except the number 8 is generated, where, Figure 4 The picture in (a) shows the situation of the unlocking interface of the random number array generated when unlocking for the nth time. Figure 4 The picture in (b) shows the situation of the unlocking interface of the random number array generated during the n+1th unlocking. Of course, correspondingly, the unlocking password preset by the user must not include the removed number, for example, the number 8 is not included.

[0057] Further, based on the Android mobile phone system, taking the unlocking interface of the random number array described in the above-mentioned embodiment 2 as an ex...

Abstract

The invention discloses a mobile phone unlocking method based on random digital arrays and a mobile phone. The method comprises the following steps: the mobile phone screen is lit up after an operating order from a user is received, an unlocking interface with a random digital array is automatically generated, and the mobile phone enters into the unlocking interface; an unlock code input by the user is received and recognized through the unlocking interface with the random digital array; and when the unlocking password input by the user is matched with a preset unlocking password, the screen of the mobile phone is controlled to be unlocked. When the mobile phone screen is unlocked with the method, the unlocking digital arrays are different every time, so as to effectively avoid the problem that the unlocking password is leaked due to touching traces left on the mobile phone screen or the unlocking gesture and movement of the user, and improve the security of the password. Meanwhile, the unlocking method provided by the invention is easy to operate and provides convenience to the user.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a method for unlocking a mobile phone based on a random number array and the mobile phone. Background technique [0002] With the development of smart phones, the current smart phones have the function of screen lock, correspondingly there are many ways to unlock the screen, the common ones are as follows: [0003] (1) Slide to unlock without a password, including the slide to unlock method of the Android system and the Apple system. This unlocking method does not have a password, and the unlocking is convenient and fast, but the confidentiality is poor. [0004] (2) Sliding unlocking with a specific pattern. This unlocking method is mainly through displaying a nine-square grid on the unlocking screen. The user slides out the preset unlocking pattern in the nine-square grid to unlock the screen. Therefore, other people may restore the user's unlock pattern based on the trace or t...
