Thereafter, the mobile terminal 100 may not be used for a predetermined period, or may enter the lock state 430 through a key operation of the user.

When a predetermined lock pattern is inputted to the mobile terminal 100 entering the lock state 430, the lock state 430 is entered and when a touch of a pattern different from the preset lock pattern is inputted, the lock state 430 ).

In addition, by releasing the lock pattern setting in the released state 420, the mobile terminal can again enter the normal state 410. [

However, since a touch input of a specific pattern for releasing the lock state is provided as a combination of single touches, there is a security problem that a touch input of a specific pattern input to another person can be easily exposed. Accordingly, in addition to a pattern composed of a combination of predetermined single touches, a touch input of a pattern capable of enhancing security is required.

Accordingly, the present invention provides a method for causing a specific pattern for releasing the lock state to be composed of a combination of a single touch and a multi-touch in order to solve the security problem described above.

Here, the multi-touch means an input in which a plurality of touch buttons are simultaneously touched. For example, the single touch is a touch input to the touch button a, and the multi-touch refers to a simultaneous touch input to the touch button a, the touch button b, and the touch button c.

Specific details of the present invention will be described below with reference to Fig.

5 is a flowchart illustrating an example of setting a screen lock pattern using a combination of a single touch and a multi-touch according to an embodiment of the present invention.

First, the control unit 180 controls the plurality of touch buttons for setting the lock pattern combination to be displayed on the touch screen (S510).

6 is a diagram illustrating an example of displaying a plurality of touch buttons for setting a lock pattern combination according to an embodiment of the present invention.

Referring to FIG. 6, a plurality of touch buttons 600 are displayed on a touch screen for a user to input a touch of a specific pattern by a combination of a single touch and a multi-touch.

Although a plurality of touch buttons 600 are shown as an example in FIG. 6, an area for receiving a user's touch may be implemented as a plurality of images.

Thereafter, the user can set a lock pattern combination in the mobile terminal 100 using the single-touch and multi-touch.

FIG. 7 is a diagram illustrating an example of setting a screen lock pattern using a combination of a single touch and a multi-touch according to an embodiment of the present invention.

Referring to FIG. 7, the user can set the B touch button 610 among the plurality of touch buttons 600 as a single touch.

Next, the user can set the F button 622 and the H button 621 among the plurality of touch buttons 600 to multi-touch.

Also, the user can set the I button 630 of the plurality of touch buttons 600 as a single touch.

Therefore, the controller 180 controls the lock state to be released only when a touch is input in the order of B (single touch) -H and F (multi-touch) -I (single touch) in the locked state of the mobile terminal 100 .

5, the user can receive a touch of a predetermined pattern from the user using the single touch and / or multi-touch to release the lock screen mode in the locked state of the mobile terminal 100 (S530).

Thereafter, the control unit 180 cancels the lock screen mode only if the preset lock pattern combination matches the touch pattern input by the user, and if not, the lock screen mode is maintained (S540).

According to the present invention, since the touch input of a specific pattern predetermined to release the lock state can be composed of a combination of a single touch and a multi-touch rather than a combination of simple single touches, The security of the security function of the security function is enhanced.

Further, according to an embodiment of the present invention, additional information for notifying the password set by the user using the single-touch and multi-touch may be further displayed in a predetermined area of the touch screen.

8 is a diagram illustrating an example of displaying information on a screen lock pattern set using a combination of a single touch and a multi-touch according to an embodiment of the present invention.

Referring to FIG. 8, the user can set the B touch button 610 among the plurality of touch buttons 600 as a single touch. In this case, the control unit 180 can control the information 710 indicating that the B touch button is input by the single touch to be displayed in the upper area of the touch screen.

Next, the user can set the F button 622 and the H button 621 among the plurality of touch buttons 600 to multi-touch. In this case, the control unit 180 can control the information (721, 722) indicating that the F button 622 and the H button 621 are multi-touchly displayed on the upper area of the touch screen.

Also, the user can set the I button 630 of the plurality of touch buttons 600 as a single touch. In this case, the controller 180 may control the information 730 informing that the I button 630 is input as a single touch to be displayed in the upper area of the touch screen.

In addition, when there is a limitation in the area for displaying information as shown in Fig. 8, the information may be displayed by a method in which the previously designated touch button information is destroyed and new information is added to the right side.

Accordingly, the control unit 180 can release the locked state only when a touch is input in the order of B (single touch) -H and F (multi-touch) -I (single touch) in the locked state of the mobile terminal 100 Information can be provided to the user separately.

In this case, in order to distinguish the single touch from the multi-touch, a predetermined visual effect can be given to display the information so that the single touch and the multi-touch are distinguished from each other.

The visual effects that can be set by the control unit 180 include a color change, a sharpness change, a transparency change, and the like.

For example, the controller 180 controls the information on the button selected by the single touch to be displayed in yellow, and the information on the plurality of buttons selected by the multi-touch may be displayed in blue.

Meanwhile, according to another embodiment of the present invention, a plurality of lock status screens may be set, and one of the plurality of lock status screens may be applied to the mobile terminal 100.

For example, the plurality of lock modes may include a personal lock mode, a general lock mode, and other lock modes.

When the mobile terminal 100 in the personal lock mode enters a predetermined pattern of touches and the locked state is released, the user can use the entire functions related to the mobile terminal 100. [

On the other hand, when the mobile terminal 100 in the normal lock mode receives a touch of a predetermined pattern and the lock state is released, the user can use only the local function related to the mobile terminal 100. [

In addition, when the mobile terminal 100 in the other locked state receives a touch of a predetermined pattern and the locked state is released, the user can use at least one function previously designated in association with the mobile terminal 100. [

However, it should be understood that the above-described personal lock mode, general lock mode, and other lock modes are merely one example to which the present invention can be applied, and that the present invention can be embodied in various forms.

Hereinafter, for convenience of explanation, it is assumed that a plurality of lock modes that can be designated by the user are a personal lock mode, a general lock mode, and other lock modes.

The user can set a touch input for releasing the lock state of different patterns in the individual lock mode, the general lock mode and the other lock mode. Of course, when a touch input is set in each of the personal lock mode, the general lock mode and the other lock mode, a single pattern and a multi-pattern are used together.

In addition, the personal lock mode, the general lock mode, and other lock modes can be changed and set through user's key operation, touch input, and the like.

That is, when the user inputs a specific key button to the mobile terminal 100 in which the personal lock mode is set, the mobile terminal 100 may be set to the general lock mode.

In addition, when the user inputs a touch of a specific pattern to the mobile terminal 100 having the general lock mode, the mobile terminal 100 may be set to the other lock mode. The touch of a specific pattern is long touch. Double touch, touch input of a predetermined pattern, and the like.

9 is a diagram illustrating an example in which a plurality of lock screen modes are changed through touch input of a specific pattern according to an embodiment of the present invention.

In Fig. 9, it is assumed that a double touch is used as a touch input of a specific pattern to change a plurality of lock modes to each other.

Referring to FIG. 9, a personal lock mode 810 is set in the mobile terminal 100.

At this time, the user can double-touch (830) a predetermined area of the touch screen. Until the double touch of the user is recognized, the mobile terminal 100 has the personal lock mode 810 set. If the double touch is recognized, the controller 180 controls the mobile terminal 100 to set the general lock mode 820. [

Therefore, after the double touch 830 is input, the lock state of the mobile terminal 100 can be released only when a touch of a predetermined pattern corresponding to the general lock mode 820 is input.

In addition, even when the locked state is released, not all functions are available to the user, and only functions of the local mobile terminal 100 can be used.

Therefore, when the mobile terminal 100 is turned over to another person, the user can easily set the general lock mode 820 to the mobile terminal, and even if the other person releases the locked state of the mobile terminal 100, So that the effect of further enhancing the security of the mobile terminal 100 is assured.

Meanwhile, according to another embodiment of the present invention, the controller 180 may control the indicator to be displayed separately to notify the user of the lock mode currently being applied to the mobile terminal 180.

10 is a view illustrating an example of displaying an indicator informing a currently set lock picture mode among a plurality of lock picture modes according to an embodiment of the present invention.

Referring to FIG. 10, when the personal lock mode 810 is set in the mobile terminal 100, the controller 180 controls the first indicator 910 to be displayed on a predetermined area of the touch screen.

If the lock mode set in the mobile terminal 100 is changed from the personal lock mode 810 to the general lock mode 820, the controller 180 notifies the second indicator 920 to a predetermined area As shown in FIG.

Although not shown, it is obvious that a third indicator for indicating the conversion to the other lock mode can be further displayed.

Accordingly, the user can conveniently grasp the lock mode currently applied to the mobile terminal 100, which is convenient.

According to an embodiment of the present invention, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal having the display unit capable of displaying the stereoscopic image as described above can be applied to the configuration and method of the embodiments described above in a limited manner, All or a part of the above-described elements may be selectively combined.
