3 is a flowchart illustrating a security method performed by a communication terminal apparatus according to an embodiment of the present invention.

As described above, the security method of the communication terminal apparatus according to the embodiment includes a step of processing to a first security setting state in which the use of the plurality of functions is restricted when the operating environment satisfies the security setting condition in the state that the interlocking apparatus is registered S301 to S307).

The method further includes a step (S309) of searching for a predetermined interworking device through a communication channel in a first security setting state.

The method further includes a step (S311 to S315) of changing to a second security setting state so that use of some of the plurality of functions whose usage is restricted when the signal strength of the searched interlocking device satisfies a preset level is allowed do.

Next, the method further includes steps S317 and S319 for displaying a lock screen that can be released by inputting preset information when a function whose use is restricted is selected in the second security setting state.

Hereinafter, the process of performing the security processing according to the search result of the wearable device 200 by the communication terminal apparatus 100 according to the embodiment of the present invention will be described in detail with reference to FIG. 1 to FIG.

First, the control unit 180 of the communication terminal apparatus 100 registers an interlocking device to be interlocked in advance through pairing (S301). For example, when the user selects the device registration menu, the device search unit 181 of the control unit 180 searches the periphery for an interlocking device such as the wearable device 200 using the short range communication unit 112, The device 200 can be registered in advance as an interlocking device.

The control unit 180 drives the security processing program 162 of the memory unit 160 to perform security processing according to the search result for the wearable device 200 according to the embodiment of the present invention.

Here, the control unit 180 confirms the operation environment of the communication terminal apparatus 100 (S303), and when the confirmed operation environment satisfies the predetermined security setting condition (S305), the use of the plurality of functions is limited The security state of the communication terminal apparatus 100 is processed so as to be placed in the first security setting state (S307). For example, if no key input data is generated through the user input unit 140 or a touch input is not generated on the touch screen of the display unit 151, the lock screen 101 is output through the display unit 151 , It is possible to maintain the first security setting state in which the use of the entire function including the telephone function is restricted until the security setting is canceled by inputting predetermined information in the lock screen 101. [

In this way, in the state where the first security setting state is maintained, according to the security processing procedure by the security processing program 162, the device search unit 181 uses the short range communication unit 112 to interlock with the wearable device 200, It is searched whether there is a device (S309).

Next, the security processing unit 182 detects that the interlocking device such as the wearable device 200 is present by the device search unit 181 (S311), and searches the interlocking device such as the wearable device 200 that is searched and paired It is determined whether the signal strength satisfies a predetermined level (S313). For example, the security processing unit 182 compares the Received Signal Strength Indication (RSSI) and the RTD (Round Trip Delay) with predetermined values to determine whether the interlocking device such as the wearable device 200 is located in the short distance from the communication terminal device 100 Can be confirmed. Here, the RSSI and the RTD may be directly measured by controlling the local communication unit 112, or may be used if there is a value measured for another function in an operating system API (Application Programming Interface) or the like.

When the signal strength of the interlocking device, such as the wearable device 200, etc., detected by the device search unit 181, satisfies a predetermined level, the security processing unit 182 performs use of some of the plurality of functions whose use is restricted The security state is changed from the first security setting state to the second security setting state (S315). For example, some functions that do not infringe on a user's privacy may be readily available and may be used for other functions that access or utilize sensitive data such as personal and financial information, game money, etc. I can not.

In addition, when a function whose use is restricted in the second security setting state is selected (S317), the security processing unit 182 displays a lock screen that can be released by inputting predetermined information in the same manner as the lock screen of the first security setting state And controls the display unit 151 of the output unit 150 (S319).

In this case, even if a wearer wears the wearable device 200, the limited function can be used in step S315 only by inputting predetermined information on the lock screen of the second security setting state. For example, if the authentication information such as a password, a pattern, or a fingerprint previously set in the lock screen according to the second security setting state is correctly input, the screen lock state is canceled.

Meanwhile, the device search unit 181 periodically checks the signal strength of the interlocking device such as the wearable device 200 even after the device search unit 181 is changed from the first security setting state to the second security setting state, and the security processing unit 182 controls the wearable device 200 and the like may be reduced to a predetermined level or lower, a power saving mode may be performed to control the display unit 151 so that the screen is turned off. Here, if the predetermined application program is running, the security processing unit 182 may determine that the screen is not turned off or may not search for the interlocking device such as the wearable device 200 by determining an exception condition. For example, when a moving image or music is being reproduced, it may be determined that the user is continuously using the communication terminal apparatus 100 regardless of the search result of the interlocking apparatus, so that the security processing may not be performed.

As described so far, according to the embodiment of the present invention, it is possible to change the security setting state of the communication terminal apparatus according to the result of searching the interlocking apparatus. In particular, in a security setting state in which use of a plurality of functions is restricted, the security setting state can be changed so that use of some functions among a plurality of functions is allowed according to a search result for the interlocking apparatus.

These computer program instructions may be loaded into a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus so that the instructions, which are executed via a processor of a computer or other programmable data processing apparatus, Lt; / RTI > These computer program instructions may also be stored in a computer usable or computer readable memory capable of directing a computer or other programmable data processing apparatus to implement the functionality in a particular manner so that the computer usable or computer readable memory It is also possible to produce manufacturing items that contain instruction means for performing the functions described in each step of the flowchart. Computer program instructions may also be stored on a computer or other programmable data processing equipment so that a series of operating steps may be performed on a computer or other programmable data processing equipment to create a computer- It is also possible for the instructions to perform the processing equipment to provide steps for executing the functions described in each step of the flowchart.

In addition, each step may represent a module, segment, or portion of code that includes one or more executable instructions for executing the specified logical function (s). It should also be noted that in some alternative embodiments, the functions mentioned in the steps may occur out of order. For example, the two steps shown in succession may in fact be performed substantially concurrently, or the steps may sometimes be performed in reverse order according to the corresponding function.
