Description
Technical field
The present invention relates to terminal device technical field more particularly to a kind of unlocking method and systems of mobile terminal.
Background technique
With the development of society, the universal and intelligent of mobile terminal (such as mobile phone, tablet computer) also becomes as one kind
Gesture.For example original is perhaps two people or more people using the same mobile terminal, almost everyone respectively possesses one till now
Or multiple mobile terminals.The owners of many terminals it is not desirable that some private informations in oneself terminal are seen by other people, than
Such as message registration, short message, web page browsing record and some application such as QQ, microblogging class remember account number cipher.
Currently, one screen lock usually is set to mobile terminal in order to meet the needs of equipment owner protects privacy,
The screen lock can be unlocked by the unlocking pattern of user's input or fingerprint, numerical ciphers etc..But under public environment, use
During family is unlocked by the front screen of mobile terminal, inevitably there is the leakage of unlocking information and cause to move
The safety of dynamic terminal reduces.With the trend that the screen size screen enlarging of the mobile terminals such as mobile phone, tablet computer develops, and
People generally use the mode that is hold by one hand using mobile terminal, and it is excessive and go out that screen is possibly used for when carrying out front unlock
The phenomenon that existing mobile terminal slides mobile phone, there are security risks.
Application No. is the Chinese invention patents of CN201410317147.3 to disclose a kind of unlock side based on pattern screen locking
Method and mobile terminal.Wherein, unlocking method includes：The screen locking pattern that user draws on the screen is received, screen locking pattern includes connecting
The circular track at the straight path and at least one of them node of at least two nodes centered on node is connect, around track
Pass through multiple preset coordinate points in a predetermined order；The track of screen locking pattern and the coordinate information of each point of screen locking pattern are recorded,
Coordinate information includes the sequencing that coordinate position and coordinate occur；Judge that track and the screen locking pattern of screen locking pattern are each
Whether the coordinate information of point matches with the screen locking information prestored；If successful match, carries out unlocking screen and mentioned if it fails to match
Show that unlocking screen fails.
Above-mentioned is in the prior art that the pattern drawn based on user is unlocked for the unlocking method of screen, is pair
The raising for changing to realize the safety of mobile terminal of the drawing process of the unlocking pattern.But the and unresolved prior art
It is middle because carrying out the problem of being easy leakage unlocking information in front screen unlock under public environment, and then lead to the peace of mobile terminal
Full hidden danger.In addition, the screen size of Nowadays mobile terminals is gradually increased, it is easy to keep mobile phone etc. mobile when being unlocked using one hand
Terminal landing damages.
Summary of the invention
In view of the above-mentioned problems, the unlocking method includes following step the invention discloses a kind of unlocking method of mobile terminal
Suddenly：
S1：Obtain the unlocking pattern that user is drawn on backside touch screen；
S2：Unlock picture is generated according to the unlocking pattern；
S3：Judge to unlock whether picture matches with the first default picture；
S4：If unlock picture matches with the first default picture, mobile terminal is unlocked.
Further, above-mentioned steps S1 includes：
S11：Monitoring judges whether current front touch-screen is in screen lock state；
S12：If so, obtaining the unlocking pattern that user is drawn on backside touch screen.
It further, further include step before above-mentioned steps S1：
Preset initial the unlocking pattern；
According to initial unlock pattern generation portion the first default picture identical with the screen size of backside touch screen, and protect
Deposit the first default picture.
It further, further include step after above-mentioned steps S4：
S5：If unlocking picture and the first default picture mismatching, unlock failure information is sent to remind user to solve again
Lock.
Further, the screen size of above-mentioned backside touch screen is less than the screen size of front touch-screen, and the back side is touched
The screen size of the screen size and front touch-screen of touching screen is proportional.
Based on a kind of unlocking method of mobile terminal provided by the present invention, the invention also discloses a kind of mobile terminals
System for unlocking, the system for unlocking include：
Pattern obtains module, the unlocking pattern for being drawn on backside touch screen for obtaining user；
Image generating module, for generating unlock picture according to the unlocking pattern；
Judgment module, for judging whether above-mentioned unlock picture matches with the first default picture；
Unlocked state, for unlocking mobile terminal when above-mentioned unlock picture and the first default picture match.
Further, above-mentioned system for unlocking further includes：
Presetting module is used for preset initial the unlocking pattern；
Picture processing module, for identical with the screen size of backside touch screen according to initial unlock pattern generation portion
First default picture, and save the first default picture.
Further, above-mentioned system for unlocking further includes：
Reminding module, for when unlocking picture and above-mentioned first default picture and mismatching, send unlock failure information with
User is reminded to unlock again.
Further, above-mentioned pattern acquisition module includes：
Monitoring module judges whether current front touch-screen is in screen lock state for monitoring.
Further, the back side setting one of above-mentioned mobile terminal is reduced with the proportional example of screen size of front touch-screen
Backside touch screen.
The beneficial effects of the present invention are：
A kind of unlocking method and system of mobile terminal disclosed in this invention is by being arranged at the back side of mobile terminal
One backside touch screen corresponding with front touch-screen, in order to user be hold by one hand mobile terminal carry out unlocking screen when energy
It is enough to be unlocked operation by touching backside touch screen, this method can be convenient for user's one hand also can be avoided while unlock because
Safety problem caused by the existing unlocking information leakage of front unlock.In addition, also by by backside touch screen be designed as with
The relationship that the proportional example of the screen size of front touch-screen reduces, in order to which user can be more just when using large screen cell phone
Prompt carry out back side unlock has preferable practicability.
