Embodiment Construction

[0020] see figure 1 , figure 1 It is a flowchart of an unlocking method based on a pattern lock screen provided by an embodiment of the present invention. This embodiment is described from the perspective of a mobile terminal implementing an unlocking method between a pattern lock screen. The unlocking method of this embodiment includes:

[0021] S101: Receive a screen lock pattern drawn by the user on the screen, the screen lock pattern includes a straight line connecting at least two nodes and a circle around the node at least one of the nodes, and the circle around the track passes through multiple presets in a predetermined order. set coordinate point;

[0022] When the user needs to set the screen lock, the lock screen pattern is preset and saved, and then the screen is unlocked by inputting the lock screen pattern. Only when the input lock screen pattern is consistent with the preset lock screen pattern can the screen be unlocked. Otherwise, screen unlocking fails.

Abstract

The invention discloses an unlocking method based on pattern screen locking and a mobile terminal, wherein the unlocking method comprises the following steps that a screen locking pattern drawn on a screen by a user is received, wherein the screen locking pattern comprises a linear track connecting at least two nodes and a surrounding track using the node as the center in a position of at least one node, and the surrounding track passes through a plurality of preset coordinate points according to the preset sequence; the tracks of the screen locking pattern and the coordinate information of each point of the screen locking pattern are recorded, and the coordinate information comprises coordinate positions and coordinate occurring sequences; whether the track of the screen locking pattern and the coordinate information of each point of the screen locking pattern are matched with the preset screen locking information or not is judged; if the matching is successful, a screen is unlocked; if the matching is not successful, the screen unlocking failure is promoted. Through adopting the mode, the unlocking method has the advantage that the safety performance of the screen locking can be improved.

Description

technical field [0001] The invention relates to an unlocking method based on a pattern lock screen and a mobile terminal. Background technique [0002] With the development of society, the popularization and intelligentization of mobile terminals such as mobile phones and tablet computers has also become a trend. For example, maybe two or more people used the same mobile terminal in the past, but now almost everyone owns a mobile terminal, and the mobile terminal has gradually become a personal property of the individual. Many terminal owners don't want some information in their terminal to be seen by others, such as call records, short messages, web browsing records, and some applications such as QQ and Weibo remember account passwords, etc. [0003] At present, in order to meet the privacy protection needs of device owners, a screen lock is usually set for the mobile terminal, and the screen can only be turned on only when the input screen lock is consistent with the pres...
