FIG. 2 is a flowchart illustrating the operation of the smartphone shown in FIG. 1, and FIG. 3 is a schematic diagram illustrating the functions of the smartphone shown in FIG. 1 when entering a child protection zone and exiting from the child protection zone. .

The operation of the locking and unlocking app 113 will be described in detail with reference to FIGS. 1 to 3.

The locking and unlocking app 113 running on the smartphone 100 sets the protected area using the protected area location values (or coordinates; P1 to P4) (S110). The number of protected areas to be set is determined according to the protected area location values. The protected area location values P1 to P4 are stored in the memory 140 by the AP 110 and used by the application 113 to set the protected area.

The locking and unlocking app 113 acquires the first location information of the smartphone 100 held by the user moving at the first point in real time, and uses the obtained first location information to the smartphone 100 The first location of the user using is calculated in real time (S115).

The locking and unlocking app 113 determines whether the user has entered the protected area using the protected area and the first location set in step S110 (S120). When the first location exists in the set protected area, that is, when it is determined that the user has entered the protected area (YES in S120), the locking and unlocking app 113 activates the locking function of the smartphone 100 (S125) .

However, when the first location exists outside the set protected area, that is, when it is determined that the user has not entered the protected area (NO in S120), the locking and unlocking app 113 calculates the location of the user moving in real time (S115). ).

The locking and unlocking app 113 acquires second location information of the smartphone 100 held by the user moving from a second point of time later than the first point of time, and uses the acquired second location information to The second location of the user of (100) is calculated in real time (S135).

The locking and unlocking app 113 determines whether the user has advanced from the protected area using the protected area and the second location (S140).

When a second location exists outside the set protected area, that is, when it is determined that the user has advanced from the protected area (YES in S140), the locking and unlocking app 113 deactivates the locking function of the smartphone 100.

However, when a second location exists within the set protected area, that is, when it is determined that the user has not yet advanced from the protected area (NO in S140), the locking and unlocking app 113 activates the locking function of the smartphone 100. Keep it as it is.

According to embodiments, each of the first location information and the second location information is obtained by the lock and unlock app 113 based on the location information signal output from the GPS receiver 120 included in the smartphone 100 Can be.

According to embodiments, each of the first location information and the second location information is locked and unlocked based on the location information signal output from the communication module 125 or the WiFi module 130 included in the smartphone 100 It can be obtained by the app 113.

When it is determined that the user has entered the protected area (YES in S120), the locking and unlocking app 113 outputs an entry notification message using the output device 160 and/or 170 of the smartphone 100, and the When it is determined that the user has advanced from the protected area (YES in S140), the locking and unlocking app 113 outputs an advance notification message using the output device (160 and/or 170) of the smartphone 100. . Thus, the user can know whether he has entered (entered) the protected area and has exited (exited) from the protected area.

According to embodiments, step S135 may be performed after step S125, or may be performed after step S130.

When step S130 is performed, the locking and unlocking app 113 determines whether there is an attempt to use (or execute) a specific app, for example, the first application 115, that is, an emergency call app (S130). If there is no attempt to use a specific app (NO in S130), the locking and unlocking app 113 performs step S135.

However, if there is an attempt to use a specific app (YES in S130), the locking and unlocking app 113 acquires an execution command of a specific app, for example, the first application 115, that is, an emergency call app (S130), and Based on the execution command, it is determined whether the application is allowed to be executed even while the lock function of the smartphone 100 is activated (S155).

When the first application 115 is an application permitted to be executed (YES in S155), the locking and unlocking app 113 allows the execution of the first application 115 (S160).

However, when the first application is the Internet app 117 or the messenger app 119, that is, when the first application 117 or 119 is not an application permitted to be executed (NO in S155), the locking and unlocking app 113 ) Blocks the execution of the first application 117 or 119 (S170).

In the step (S125) of the locking and unlocking app 113 activating the locking function of the smartphone 100 according to embodiments, the locking and unlocking app 113 is a button 190 installed on the smartphone 100 Alternatively, the AP 110 receiving an interrupt output from a key displayed on an input GUI (graphical user interface) may cause the AP 110 to ignore the interrupt.

In the step of activating the locking function of the smartphone 100 by the locking and unlocking app 113 according to embodiments (S125), the locking and unlocking app 113 is a screen brightness function installed on the smartphone 100 ( For example, a screen brightness function of the display device 160) may be controlled to the lowest level.

In the step S125 of activating the locking function of the smartphone 100 by the locking and unlocking app 113 according to embodiments, the locking and unlocking app 113 is a touch screen panel installed on the smartphone 100 ( 150) can be disabled.

In the step of activating the locking function of the smartphone 100 by the locking and unlocking app 113 according to embodiments (S125), the locking and unlocking app 113 is the unlocking pattern and password of the smartphone 100 The input window or the biometric information input function can be disabled.

After each of the steps S160 and S170 is performed, the step S130 or S135 is performed.

A computer program that executes a method of locking and unlocking the smartphone 100 using the user location information (eg, the locking and unlocking app 113) is a computer-readable storage medium or a recording medium 140 ), and the computer program can be executed by the AP 110.

The present invention has been described with reference to the embodiments shown in the drawings, but these are only exemplary, and those of ordinary skill in the art will appreciate that various modifications and other equivalent embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical idea of the attached registration claims.
