Referring to FIG. 6, the controller 180 displays a screen corresponding to the setting of the locked state on the display unit 151 (S300). The screen corresponding to the setting of the locked state may be displayed when the portable terminal 100 is powered on, or a touch input or a key input may not be displayed for a predetermined time or may be displayed according to a user command.

In a state where a screen corresponding to the setting of the lock state is displayed, the controller 180 determines whether any one of a preset unlock pattern input is input for unlocking (S305). The unlock pattern input refers to an input in which a form of the dragged path corresponds to a preset pattern among touch and drag inputs through the display unit 151. The unlock pattern input or the lock pattern input may be preset by the user, and a separate menu may be provided for this purpose.

As a result of the determination in step S305, if any one of the preset unlock pattern input is input, the controller 180 releases the lock state (S310). When the lock state is released, a notification signal such as a sound effect or a tactile effect corresponding to the release of the lock state may be output.

After releasing the locked state, the controller 180 controls the preset operation mode to be set in response to the input unlocking pattern (S315).

In this case, examples of the operation mode set according to the input unlock pattern include a default mode, a personal mode, a privacy mode, and the like. Here, the default mode is a basic use mode, which is an operation mode that is basically set at the time of manufacturing the portable terminal 100. Such a default mode may be used even when the mobile terminal 100 is loaned to another user for a call or the like.

The personal mode is an operation mode set by changing the environment according to the user's use. For example, decorate the wallpaper and place custom applications on the screen where it is easy to run. The default and individual modes can share applications, phone books, and text messages. That is, an application installed in one operation mode or all stored contents can be set to be used in another operation mode. Personal mode has a wide range of applications, such as office work mode, exercise mode, sleep mode, dating mode.

Privacy mode is a mode for dealing with extremely personal and important content. This mode is suitable for storing important data or creating a personal environment. To access this mode of operation, you can add options such as having to enter the unlock pattern more than once in a row to increase security. . Applications or content stored in the privacy mode are not accessible in other modes of operation, but only configured in the privacy mode. You can create multiple private or privacy modes

If the user wants to use another operation mode in one operation mode, the screen corresponding to the lock setting is displayed again, and the unlock pattern corresponding to the operation mode to be used is input.

In this manner, the predetermined operation mode may be set at the same time as the lock state is released according to the unlock pattern input.
