Figure 11 illustrates a method of activating a deactivated application, in accordance with an embodiment of the present invention.
According to FIG. 11A, the applications corresponding to the bank transfer service are in the inactive state. This is because the unlocking method is performed by inputting a pattern lock or knock code corresponding to security class 'middle' or 'lower'. Therefore, when clicking the disabled applications at this time, the following operations are performed.
Referring to FIG. 11 (b), a message indicating that a higher level of authentication is required than the current security level is required to activate the selected icon and a security method corresponding to the required security level are displayed in the dialog window. For example, the security method may be a confirmation of whether or not the fingerprint is matched with a previously stored fingerprint through fingerprint input. The fingerprint input includes a fingerprint input through a rear input unit as well as a fingerprint input in a partial area of the display unit on the front side.
According to (c) of FIG. 11, when the fingerprint input is completed and the fingerprint matches, the disabled application is changed to the active state.
Meanwhile, FIG. 12 illustrates a method of rearranging icons according to security level according to an embodiment of the present invention.
According to FIG. 12 (a), some of the applications displayed on the screen have a security level set. When a specific input is applied to the icons of these applications, the icons may be rearranged according to the security level. At this time, the input for rearranging may select the specific menu for rearrangement of icons according to the security level by long-pressing the icons. In addition, when a folder is created for rearranging the icons, the user can inquire whether to rearrange the icons according to the security level. In addition, when a security level is displayed on some of the icons, an input can be received from any one of the icons having the security level.
In addition, according to FIG. 12B, when an input is received from any of the icons having the security level, the icons having the same security level as the security level can be displayed in a separate window. By the operation of displaying in the separate window, it is possible to decide whether to move all or a part of the icons to one folder from the user. In addition, the display may also receive consent from the user to move all of the icons to one folder.
Also, according to (c) of FIG. 12, after determining whether the fingerprint input is coincident with the user, the icons can be rearranged according to the security level. In addition, an icon to be added to the folder of the specific security level among the icons of the application whose security level is not set can be received from the user.
Meanwhile, the method of releasing the locked state of the screen of the mobile terminal and the method of executing the application according to the security level based on the method can be performed by the following procedure. 13 is a flowchart illustrating a method of releasing a locked state of a screen of a mobile terminal according to the present invention and a method of executing an application based thereon. The method of releasing the locked state of the screen and the method of executing the application can be performed by the
The method of releasing the locked state of the screen includes a deactivation state determination process S1310, a contact state detection process S1320, and a fingerprint recognition sensor activation process S1330.
In addition, the method of releasing the lock state of the screen may further include a first lock state releasing step (S1340) or a second lock state releasing step (S1350).
The inactivation state determination process (S1310) determines whether the screen of the display unit mounted on the main body is in an inactive state. The deactivation state includes a case where the user's input from the mobile terminal does not exist for a predetermined time or does not perform communication with an external device.
The contact state sensing process S1320 detects whether the main body is in contact with the user's body by the second sensor corresponding to the contact sensor or the SAR sensor.
In addition, the contact state sensing step S1320 may detect whether the rear surface of the main body is in contact with the user's body or in a state of being placed on the surrounding object. Here, the contact state sensing process (S1320) may determine whether the contact state or the placement state is determined based on the amount of change in the capacitance of the contact sensor. In this regard, the detailed description is replaced with the description in FIG.
The fingerprint recognition sensor activation process S1330 may include activating a fingerprint recognition sensor corresponding to the first sensor to detect a fingerprint of a user contacting the button receiving the input of the user when the second sensor detects contact of the human body do. In addition, the fingerprint recognition sensor activation process (S1330) controls the rear input unit so that the fingerprint recognition sensor is activated when the rear surface is in the contact state in an idle screen state in which the screen is in an inactive state. That is, if the rear surface is in the contact state in the idle screen state, the fingerprint recognition sensor can be activated to control the rear input unit so that the button touch input from the rear input unit is detected as the fingerprint input.
If the fingerprint sensed by the first sensor corresponds to the preset fingerprint, the first lock state canceling process (S1340) releases the locked state. That is, the first lock state canceling process (S1340) cancels the locked state of the screen based on whether the fingerprint input from the rear input unit matches the previously stored fingerprint of the user.
The second lock state canceling process (S1350) controls the display unit to release the locked state of the screen based on the release input on the display unit from the user when the screen is in the inactive state and the rear side is in the deployed state. Here, the cancel input may include at least one of a pattern cancellation input according to coincidence with a previously stored pattern, a knock cancel input according to whether or not the divided area on the display matches the touch, It can be one.
Meanwhile, the method of releasing the locked state of the screen may further include a screen display process (S1360) and a security setting process (S1370).
In the screen display process (S1360), when the screen is unlocked, the application displayed or activated on the display unit controls the screen to be different depending on the security level of the unlocked method. Here, the priority of the security class may be determined according to the priority of the fingerprint input, the pin code input, the pattern release input, and the knock release input.
The security setting process (S1370) controls the display unit to receive additional input from the user for execution of the application when an execution input is detected in the disabled application. Wherein the further input may be at least one of the fingerprint input and the pin code input.
In addition, the method of releasing the locked state of the screen may further include a transmission power control process (S1380). The transmission power control step S1380 controls the radio communication unit to reduce the transmission power if the transmission power of the radio communication unit is greater than a predetermined value when the mobile station is in a contact state.
