Embodiment 1

[0024] figure 1 It is a flow chart of a method for unlocking a mobile terminal provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of unlocking mobile terminals such as mobile phones, personal digital assistants or tablet computers, and the method can be executed by the mobile terminal , including:

[0025] S110. Obtain the password text in the Chinese password sentence set by the user, and determine the candidate text.

[0026] The user can set the unlocking password of the mobile terminal as a Chinese password statement, and after receiving the Chinese password statement set by the user, the mobile terminal obtains the password text in the Chinese password statement. Then determine the candidate text, the candidate text can be randomly selected text not associated with the cipher text, or the text associated with the cipher text, for example, preferably, according to each cipher text and the relationship between the cipher text ...

Embodiment 2

[0038] figure 2 It is a flow chart of an unlocking method for a mobile terminal provided in Embodiment 2 of the present invention. This embodiment provides a preferred method for determining candidate characters, specifically as follows:

[0039] S210. Segment the Chinese password sentence by using the Chinese word segmentation technology to obtain the password text of the Chinese password sentence.

[0040] Wherein, the Chinese password sentence is a password set in advance by the user.

[0041] The mobile terminal uses the Chinese word segmentation technology to segment the Chinese password sentence, divides the Chinese password sentence into individual words, and then obtains the password text of the Chinese password sentence according to each word. For example, if the Chinese password sentence set by the user is "I love Baidu", the words obtained after the Chinese word segmentation are "I", "Love" and "Baidu", where "I" is a pronoun and "Love" is a verb. "Baidu" is a no...

Embodiment 3

[0062] Figure 5 It is a schematic diagram of an unlocking device for a mobile terminal provided in Embodiment 3 of the present invention, as shown in Figure 5 As shown, the unlocking device for a mobile terminal provided in this embodiment includes: a character determination module 510 , a character display module 520 , a Chinese sentence composition module 530 and an unlocking module 540 .

[0063] Wherein, the text determination module 510 is used to obtain the password text in the Chinese password sentence set by the user, and determine the candidate text;

[0064] The text display module 520 is used to display the password text and candidate text on the unlocking interface;

[0065] The Chinese sentence composition module 530 is used for receiving the text selected by the user, and forms the Chinese sentence according to the order in which the user selects the text;

[0066] The unlocking module 540 is used for performing an unlocking operation when the Chinese sentenc...

Abstract

The invention discloses an unlocking method and device of a mobile terminal. The unlocking method comprises following steps: acquiring password characters of Chinese password sentences set by a user and determining candidate characters; displaying password characters and candidate characters on an unlocking interface; receiving characters selected by the user and forming Chinese sentences according to the sequence of characters selected by the user; and performing unlocking operation when Chinese sentences are the same with Chinese password sentences. The unlocking method and device of the mobile terminal have following beneficial effects: Chinese sentences are utilized as unlocking passwords; due to vast number of Characters, display positions of an unlocking interface vary so that complexity of passwords is enhanced; and due to relevance of characters, memory difficulty is decreased so that convenience of middle-aged and aged people for usage of high-intensity passwords is enhanced.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for unlocking a mobile terminal. Background technique [0002] With the rapid development of communication technology, intelligent mobile terminals have achieved unprecedented development, and there are more and more applications on mobile terminals, resulting in the preservation of a lot of personal privacy of users. Once the mobile terminal is lost, it will bring unpredictable Loss. Therefore, it is necessary to set an unlock password to avoid leakage of privacy. [0003] The unlocking methods of existing smart mobile terminals generally include digital unlocking, letter symbol unlocking and Jiugongge sliding unlocking. Simple digital passwords or simple connecting patterns in the nine-square grid are easy to be leaked or cracked by others peeping, while more complex alphabetic passwords or complex unlocking patterns in the nine-squar...
