Embodiment 1

[0041] This embodiment provides a method for unlocking a mobile terminal, such as figure 1 As shown, the mobile terminal is a mobile phone. The present embodiment realizes the unlocking of the main screen of the mobile phone. An unlocking expression is set in the mobile phone. The unlocking expression is assumed to be a four-arithmetic expression: 1000+A+B-C, including the following steps :

[0042] Step 101, when the mobile terminal is in the locked state and receives an unlock instruction, extract all the variables in the unlock expression;

[0043] Specifically, the unlocking expression is actually a string, and the search string is not a number, not an operator, and is not some character that is completely impossible to be a variable, and the character can be extracted as a variable in the unlocking expression . After searching, the variables in the unlocking expression in this embodiment are A, B and C.

[0044] Step 102: Perform a random assignment operation on each v...

Embodiment 2

[0058] This embodiment provides an unlocking method for a mobile terminal. The difference between this embodiment and the method in Embodiment 1 is that the mobile terminal judges whether the input target expression conforms to the mathematical operation rules, and if so, uses the target expression as the unlocking expression, The unlocking expression is encrypted and stored in a location with read permission in the mobile terminal, such as limiting the unlocking expression to be read only by operating a certain application; if not, re-input the target expression.

[0059] When making a specific judgment, the user enters the target expression: 1000+A+B-C. In fact, the target expression is also a string, and each character in the string is judged. There is no divisor of 0, and the brackets are not paired. There are situations that do not conform to the mathematical operation rules, so the target expression can be used as an unlocking expression.

[0060] Such as image 3 As sh...

Abstract

The invention discloses a mobile terminal and an unlocking method thereof. The mobile terminal sets an unlocking expression, and the unlocking expression comprises at least one variable. The unlocking method includes steps that extracting all the variables in the unlocking expression when the mobile terminal is located at a locked state and receives an unlocking command; randomly assigning each variable; displaying the value of each variable and a password entry box; after the password entry box receives an input value as a password, calculating the correct result value of the unlocking expression according to the value of each variable, judging whether the input value is equal to the correct result value, if so, unlocking the mobile terminal; otherwise, enabling the mobile terminal to continue to randomly assign each variable. The unlocking method unlocks the mobile terminal through setting the unlocking expression, the unlocking difficulty is increased, the other people are difficult to decode the unlocking mode of the mobile terminal, and the universality of the mobile terminal unlocking mode is reinforced.

Description

technical field [0001] The invention relates to a mobile terminal and an unlocking method thereof. Background technique [0002] With the popularity of large-screen designs and touch screens in mobile terminals, the original hardware keyboard unlocking method is no longer applicable. Some of today's big companies, such as Apple, first invented the method of dragging the slider from left to right to unlock, and applied for related patents. [0003] In order to protect personal privacy, a function of personal identity verification or password verification is required when the screen is unlocked. For example, the Android system mobile phone launched by Google has realized the functions of identity verification and password protection through different gestures of sliding on the digital screen. However, the swipe gesture is too simple and easy to decipher. [0004] After the iPhone 5s, the Apple mobile phone introduced the fingerprint unlocking function, which uses the finger...
