The controller 180 may receive a second input pattern configured as a trajectory different from the encryption pattern corresponding to the first input pattern 10 stored in the memory a predetermined number of times in a locked state (S130).

For example, a pattern different from the first input pattern (10 of FIG. 4) (21, 22,..., 25 of FIG. 5) may be received. That is, the controller 180 may include a second input pattern (FIG. 5 of FIG. 5) configured with a trajectory different from the first input pattern (10 of FIG. 4) with respect to the plurality of figures having the same configuration as the plurality of figures arranged in FIG. 4. 21, 22, ..., 25) can be input.

When the controller 180 receives the second input pattern 21, 22,..., 25 of FIG. 5, the controller 180 may not release the locked state of the mobile terminal 100 or the touch screen 151.

In addition, in the above example, the predetermined number of times may be five times. That is, when receiving the first input pattern (10 of FIG. 4) and the second input pattern (21, 22,..., 25 of FIG. 5) differently for five times, the camera (121 of FIG. 1) is automatically driven. It may be (S140). The camera is a front camera, and may photograph a face of a user.

Thereafter, the controller 180 may determine whether the recognized face coincides with a preset user's face (S210).

When setting the locked state of the mobile terminal 100 or the touch screen 151 in the above-described embodiment, the face of the user may be registered by photographing the face of the user.

If the recognized face coincides with a preset face of the user (S210: Yes), the controller 180 may release the lock state (S220).

Referring to FIG. 7, as shown in FIG. 5, the second input pattern (21, 22,..., 25 of FIG. 5) different from the first input pattern (10 of FIG. 4) is received five or more times. In this case, the controller 180 may drive the front camera 121 (in FIG. 2A) to capture the face F1 for inputting a password pattern.

When the photographed face image F1 matches the pre-stored user face image, the controller 180 releases the lock state of the touch screen 151 and releases the lock state as shown in FIG. The screen screen may be displayed on the touch screen 151.

The home screen screen illustrated in FIG. 8 is set for convenience of description, and the controller 180 is displayed on the touch screen 151 immediately before the mobile terminal 100 or the touch screen 151 enters the lock mode. Can display a screen. A predetermined application may be executed before entering the lock mode, and the application execution screen may be displayed on the touch screen 151.

Hereinafter, the operation of the mobile terminal 100 will be described in more detail when the face image acquired through the camera does not match the previously stored face of the user.

9 is a flowchart of a control method of a mobile terminal according to a second embodiment of the present invention. 10 to 11 are diagrams for describing a method for controlling a mobile terminal according to a second embodiment of the present invention. The control method may be implemented under the control of the controller 180, and the second embodiment of the present invention may be implemented based on the first embodiment described above.

The controller 180 provides an account input screen to the touch screen 151 when the face image acquired through the camera does not match the face of the user, and when the input account matches the previously stored account. You can unlock it. On the other hand, when the process of receiving the second input pattern different from the preset first input pattern a predetermined number of times is repeated two or more times, the controller 180 and the camera (121 of FIG. 2) and the location information module (FIG. 1). 115 can be driven simultaneously.

If the face image acquired through the camera does not match with a previously stored face of the user, the controller 180 may display a preset account input screen (30 of FIG. 9) on the touch screen 151 (S211). ). The account input screen is displayed in the locked state.

For example, referring to FIG. 10, user authentication may be performed through a user's preset account such as a user's name (email) and password. That is, in this case, when input of a touch pattern different from the preset password pattern is repeated a predetermined number of times, when the face image photographed through the camera is not the same as the previously stored face image of the user, through the preset account The present invention relates to an embodiment of releasing a locked state. In particular, when the user forgets the password pattern, it may be applied when there is a possibility that the face image of the user is recognized unlike the previously stored face image.

Meanwhile, as a technology for recognizing a face in a face image acquired through a camera, various known face recognition technologies may be applied, and a detailed description thereof will be omitted.

When the error regarding the input of the password pattern occurs a predetermined number of times, the controller 180 may display a message on the touch screen 151 for recommending the input of the password pattern again. When such a process is repeated two or more times, the controller 180 can drive the camera (121 of FIG. 2) and the location information module (115 of FIG. 1).

9, the controller 180 may obtain location information of the mobile terminal 100 through the location information module (S215), and the controller 180 may acquire a face image obtained through a camera. And location information of the mobile terminal 100 may be transmitted to an external server (S217).

The external server may include a server corresponding to the e-mail account of the owner of the mobile terminal 100. The controller 180 may transmit a map M including the face image F2 captured by the camera and the location information L1 of the mobile terminal 100 obtained through the location information module, to the e-mail account. have.

Accordingly, when the owner of the mobile terminal 100 loses the mobile terminal 100, when the owner of the mobile terminal 100 wants to release the lock state through a predetermined touch pattern, the mobile terminal ( The holder of 100) and the location information of the holder can be obtained through e-mail. That is, the lost mobile terminal 100 or the stolen mobile terminal 100 can be found in an easier way.
