Meanwhile, the screen lock release function based on the movement of the portable terminal 100 may be used in combination with the touch pattern check. For example, as illustrated in FIG. 6, the touch pattern storage unit 140 may store a touch pattern set by a user, and the touch pattern comparison unit 150 may be input on the screen of the portable terminal 100. The touch pattern of the user may be compared with the touch pattern stored in the touch pattern storage 140. In this case, when the touch pattern of the user input on the screen and the touch pattern stored in the touch pattern storage unit 140 match, the controller 130 controls the image executing unit 160 to display the screen of the portable terminal 100. An image of a door and a key may be displayed on the screen, and a message for guiding the door to be opened using the displayed key may be output by voice or text. In addition, when the user drags the key to the door in response to the output guidance message, the controller 130 instructs the movement of the portable terminal 100 such as 'Please turn the key to open the door'. It may be output as a voice or text, and accordingly the motion measuring unit 110 is controlled to measure the movement of the portable terminal 100 by the user and compare the movement pattern stored in the movement pattern storage unit 120.

In addition, the controller 130 may control the image executing unit 160 to simultaneously confirm the touch pattern and to display the image of the door and the key. For example, the controller 130 displays the door and the key on the screen of the portable terminal 100 through the image execution unit 160 as shown in FIG. 7 and moves the keys touched by the user and dragged to the door image. The touch pattern comparison unit 150 may be controlled to compare the pattern with the stored touch pattern.

As a result, the movement of the portable terminal is reflected on the image of the door and the key displayed on the portable terminal so that the user may feel as if the door is actually opened using the key, and the portable terminal can be used in a familiar and convenient manner.

In addition, the first user can be authenticated based on the touch pattern, and the second user can be authenticated based on the movement of the portable terminal, thereby enhancing the security of personal information stored in the portable terminal.

8 is a diagram schematically illustrating a portable terminal for executing a screen lock release based on a movement according to another embodiment of the present invention.

Referring to FIG. 8, the portable terminal 800 according to another embodiment of the present invention may include a motion measuring unit 810, a movement pattern storage unit 820, a control unit 830, a password storage unit 840, and a password comparison. The unit 850 and the image execution unit 860 may be included. Here, the functions and operations of the motion measuring unit 810, the motion pattern storage unit 820, and the control unit 830 are functions of the motion measuring unit 110, the motion pattern storage unit 120, and the controller 130 of FIG. 1. And since the operation is the same, detailed description thereof will be omitted.

The input password is compared with the password stored in the password storage unit 840.

At this time, if the password input by the user matches the password stored in the password storage unit 840, the controller 830 may output a message indicating the movement of the portable terminal 800, after which the portable terminal 800 Secondary user authentication as described above may be performed based on the movement of the < RTI ID = 0.0 >

9 is a flowchart illustrating a screen unlocking method of a portable terminal according to an embodiment of the present invention.

1 and 9, the movement pattern storage unit 120 may store a movement pattern set for the portable terminal 100 (910). In addition, the touch pattern storage 140 may store a touch pattern set by a user (920). Here, although the drawing of the touch pattern is shown to proceed after the movement pattern, this is only an example of the order of progress, but is not limited thereto.

The image executing unit 160 may display an image of a door and a key on the touch screen of the portable terminal 100, and the controller 130 may display the image of the portable terminal 100 when the user touches the image displayed on the touch screen. The movement measuring unit 110 may be controlled to measure the movement (930). For example, as illustrated in FIG. 4, the image execution unit 160 may display a door image 410, a key image 420, a handle image 430, and a keyhole image 440 on a touch screen. . In this case, when the user drags the key image 420 through the touch screen to align the key 420 with the key hole 440, the controller 130 corresponds to dragging the key 420 from the touch screen. The response signal may be received, and accordingly, the motion measuring unit 110 may be controlled to measure the movement of the terminal 100. In this case, the controller 130 may display an image in which the key 320 is inserted into the key hole 440 when the user aligns the key 420 with the key hole 440 through the touch screen. You can also unlock the screen when the primary movement pattern is measured, such as turning the key counterclockwise after insertion.

Alternatively, the movement pattern may be combined to reinforce user authentication for unlocking the portable terminal 100. For example, in FIG. 4, after the key 420 is inserted into the key hole 440, it is determined whether the movement pattern of turning the key counterclockwise is primarily measured through the movement measuring unit 110. When the typical movement pattern is measured, it may be determined whether the secondary movement pattern of turning the handle 430 is measured. In this case, the primary motion pattern and the secondary motion pattern may be distinguished through a sound effect such as a 'click' sound or a message such as 'successful primary authentication'.

Alternatively, the screen unlocking method of the portable terminal according to an embodiment of the present invention may enhance user authentication by combining a touch pattern and a movement pattern. For example, the touch pattern storage unit 140 may set and store a touch pattern in the process of dragging the displayed key image 420 to the key hole 440 as shown in FIG. 150 may be implemented to compare the movement pattern of the key image and the stored touch pattern (940). Although the process of comparing the image display of the door and the key and the touch pattern has been described as being performed through one image, it may be performed as a separate process as described with reference to FIG. 6. In addition, the screen executed by the image executing unit 160 is not limited to FIG. 4, and various modifications are possible.

If it is determined by the touch pattern comparison unit 150 that the movement pattern of the key image and the stored touch pattern match (950), the controller 130 may output a guide message instructing the movement of the portable terminal 100. (960).

When the user moves the portable terminal 100 according to the guide message, the motion measuring unit 110 moves with respect to the movement of the portable terminal 100, the speed, acceleration, angular velocity, angular acceleration, tilt change amount, and movement for the corresponding movement direction. A motion including at least one of the distance change amount is measured (970). In this case, the movement measuring unit 110 may measure the movement from the movement in which the movement is fixed for more than the set time or more until the movement is fixed for the set time or more as one movement pattern. Alternatively, the start and end of the movement may be determined using a specific input key or a touch of a specific point, or the start and end of the movement may be determined using a preset pattern of movement. In addition, various modifications may be applied to the determination method of the start and end for recognizing the pattern of movement.

If the movement of the portable terminal 100 by the user coincides with the movement pattern stored in the movement pattern storage unit 980, the control unit 130 may open a door for the image displayed by the image display unit 160. By executing the operation and outputting a sound effect or a message corresponding thereto, the screen lock may be released (990).

10 is a flowchart illustrating a screen unlocking method of a portable terminal according to another embodiment of the present invention.

8 and 10, the movement pattern storage unit 820 may store a movement pattern set for the portable terminal 800 (1010). In addition, the password storage unit 840 may store a password set by the user (1020). Here, although the figure shows that the storage of the password proceeds after the movement pattern, this is only an example of the order of progress, but is not limited thereto.

The image executing unit 860 may display an image of a sliding door on the screen of the portable terminal 800, or display an input keypad image and a sliding door image of numbers and letters for inputting a password (1030).

11 is a diagram illustrating a touch screen image according to another embodiment of the present invention, and FIG. 12 is a diagram illustrating a page turning degree according to the movement degree of the portable terminal of FIG. 11 according to the present invention.

The portable terminal provides a touch screen image indicating a screen lock state in a screen locked state, and pre-stores a predefined touch gesture for the touch screen image. Such a touch gesture may be a single touch that is maintained at a critical time at an unspecified position.

When a single touch occurs in a non-specified position for a touch screen image, the portable terminal detects the movement of the terminal and releases the screen lock when the movement of the detected terminal is the movement of the predefined terminal. The movement of the predefined terminal may correspond to an operation of the user holding the terminal with his hand and moving it in the up, down, left, up and combined directions thereof. In general, when the user moves the terminal by hand, the terminal is rotated around the elbow axis. The portable terminal has a gyro sensor that can detect rotation, and the portable terminal corresponds to the motion of the actual user moving the terminal. The movement of the terminal can be detected using such a gyro sensor.

In an embodiment according to such a configuration, a user lifts a terminal held by a hand while maintaining a touch on an unspecified position of the lock screen for more than a threshold time, and the portable terminal may release the screen lock.

In addition, in another embodiment according to this configuration, for example, the user lifts the terminal holding the hand by holding the touch at an unspecified position of the lock screen for more than a threshold time, and then releases the touch. You can turn it off.

11 and 12 will be described in detail with reference to the above-described components.

However, the present invention is not limited thereto, and as illustrated in FIGS. 11 and 12, another touch method by the user's finger F is primarily recognized, and in this state, the portable terminal (eg, the mobile terminal) may be moved by the motion measuring unit 110. The lock may be released by recognizing the movement of 100) secondarily.

For example, the controller 130 recognizes a state of being touched with respect to the lock screen for a predetermined time, and when the touch time for the lock screen corresponding to the touch time of the preset touch pattern storage unit 140 is maintained, the controller 130 is primarily used. You can authenticate yourself as a user. However, the present invention is not limited thereto, and the pattern-based primary input by the user may include maintaining a touch of a certain area on the lock screen for a predetermined time, dragging in a predetermined direction while maintaining the touch of the lock screen, or at least two times. The touch screen may have any one of a multi-touch operation for maintaining two touch points and a dragging operation for maintaining a multi-touch.

In addition, the touch induction time according to the primary input may also be adjusted. For example, when the touch holding time is longer than a predetermined time, the controller 130 may authenticate the primary input and then detect the secondary motion of the portable terminal 100. Alternatively, the second touch input for detecting the movement of the portable terminal 100 may be input by the motion measuring unit 110 within 2 seconds of the touch holding time. In this case, when the touch holding time elapses for 2 seconds or more, it may be determined that authentication for the primary input is not allowed, and it may be required to re-enter the primary touch input again without receiving the secondary motion input. In another method, the second measurement unit may detect the movement of the portable terminal 100 only by the motion measuring unit when the touch holding time is between 1 and 2 seconds. In this case, the touch holding time may be controlled so as not to receive the second motion input in a range of less than 1 second or more than 2 seconds.

In addition, the controller 130 may first check that the touch method input by the user matches a pre-stored touch method, and then control the image executing unit 160 to output a page turning screen for the lock screen. . In this case, the controller may control the movement measuring unit to detect the movement of the portable terminal 100 and adjust the page turning degree of the lock screen according to the corresponding movement degree. For example, if the page turn of the lock screen is 1/3, 2/3 displays the lock screen, and the other 1/3 displays the main screen 1120 under the lock screen 1110 as shown in FIG. ) Can be displayed as if placed.

Preferably, the controller 130 may release the lock screen when it matches the movement of the portable terminal 100 previously stored in the movement pattern storage unit 120 while maintaining the touch. More preferably, the controller 130 may control the image execution unit 160 to adjust the page turning screen for the lock screen according to the degree of movement of the portable terminal 100 while maintaining the touch. For example, the page turning screen may be adjusted according to the degree of tilting the portable terminal to the left while the portable terminal is currently held and the corresponding touch scheme is maintained as the primary input. In this case, as shown in FIG. 12, for example, when the visible lock screen 1210 of the page turning screen is turned over by a certain area and thus more areas of the main screen 1220 are displayed, the controller 130 locks. The main screen 1220 for operating the terminal may be displayed by recognizing the release. The predetermined area may be set so that the lock screen is released when the page turning amount such as 1/2 or 1/3 is exceeded according to the movement degree of the portable terminal 100. In addition, the controller 130 detects the movement of the portable terminal 100 in a state in which the above-described touch input is maintained, and then controls the image executing unit 160 to display a page turning screen for the lock screen. In this state, the controller may release the lock screen if it detects the third input for which the current touch input is released.

That is, the user first moves the portable terminal while maintaining the touch on the lock screen in accordance with the corresponding touch method so that the page turning screen on the lock screen is displayed secondly, and again the touch input that is currently maintained in the third You can unlock the lock screen by releasing it.
