1 and 2, a device 10 includes a first output unit 100, a first input unit 102, a first communication unit 104, a first control unit 106, and a first storage unit 108, .

The first output unit 100 displays various kinds of information on the screen. The first output unit 100 according to an embodiment displays a list of information that can be remotely controlled by the device 10 on the screen. The information list capable of remote control may be a list of programs installed on the device 10 and a list of screens provided on the operating system of the device 10. [ For example, the program list may include a program such as a word program such as Microsoft word, an Internet explorer, an Internet access program such as Chrome or Safari, a video of a Gom player, And all the programs installed and downloaded in the device 10, such as a playback program. The screen list is displayed on the operating system (OS) of the device 10, such as Windows, MAC, or Linux, or on a smartphone, such as Android or iOS, The program screen may be a control panel, a system manager, a notepad, a command, a navigator, a gallery, an address book, and the like.

The first input unit 102 receives an operation signal from a user. The first input unit 102 according to an exemplary embodiment of the present invention is configured to have access authority to information that can be remotely controlled by a user. For example, among the remotely controllable information displayed on the screen through the first output unit 100, information for approving access to the remote control device 12 and information for blocking access are selectively input from the user.

The first input unit 102 may set the access right from the device user before the remote control of the remote control device 12, but may change the access right that has been set after the remote control. For example, if the user of the remote control device requests access to the information that has been blocked before the remote control, the device user can determine the permission and change the authority to allow access.

The information that the user wants to block access may be information related to the privacy of the user, such as an address book, a photo or video file, or financial information. The user can select a program to be executed to view the corresponding information or an execution screen thereof as access blocking information. For example, the user can select information having a name such as an address book, a gallery, and the like as access blocking information. For example, a program for executing a program for viewing a file such as a picture or a moving picture, for example, a video playback program, a photo viewer program, or the like, as an access blocking information and blocks execution of the program, Or block data transmission of the file. Or a command that can block execution of the program can be selected as access blocking information. As another example, the desktop of the device 10 can be selected as access blocking information. As another example, if the information that the user wants to block access is the system information of the device, the user can select the system administrator program that can confirm the system information or the execution screen thereof as access blocking information.

The first control unit 106 controls each component of the device 10. The first control unit 106 extracts an information list that can be remotely controlled and provides it to the first output unit 100. The information list to be extracted may be a program list installed in the device 10 and a screen list provided for each operating system of the device 10. [ The first output unit 100 displays the extracted remote controllable information list on the screen.

The first controller 106 according to an embodiment registers the set access right through the first input unit 102. [ The access right is set to which information is to be given to the remote control device 12 and which information is to be blocked. The first control unit 106 may store the registered access right in the first storage unit 108. [

The first control unit 106 according to an embodiment allows remote control of the remote control device 12 with respect to the information approved by the device user at the time of remote control of the remote control device 12, And blocks remote control of the remote control device 12 with respect to the blocked information.

The first communication unit 104 transmits and receives various information necessary for remote control. When the first controller 106 according to the embodiment captures the device screen, the first communication unit 104 transmits the captured device screen to the remote controller 12, and transmits the captured device screen to the remote controller 12 The control command is received. The first control unit 106 executes the received control command.

The first communication unit 104 according to an embodiment connects to the relay server 16 in order to receive a remote control service from the remote control device 12. [ In this case, the first communication unit 104 transmits a device screen to the remote control device 12 through the relay server 16 connected thereto, and transmits a control command from the remote control device 12 via the relay server 16, Lt; / RTI > The first communication unit 104 according to an embodiment transmits to the remote control device 12 a list of information approved by the device user. In this case, the remote control device 12 can select information for remote control within the list of information approved for access from the device user.

The first controller 106 according to an embodiment configures a device screen for which access has been approved and transmits the screen to the remote controller 12 through the first communication unit 104. [ Next, upon receipt of a control command from the remote control device 12 through the first communication unit 104, it is determined whether or not the received control command has occurred within the device screen area to which access has been granted. According to the determination result, the control command is executed when the control command is generated within the device screen area to which the access is approved, and the execution of the control command is inhibited when the control command is generated in the area outside the device screen area for which access is permitted. For example, if the device screen displayed on the remote control device 12 is a program screen to be executed on the desktop, if a control command is generated on the desktop outside the program screen, the first control unit 106 executes the corresponding control command . In contrast, when a control command is generated in the program screen, the first control unit 106 executes the corresponding control command. At this time, even if the user of the remote control apparatus changes the position of the execution program screen through a mouse operation or the like within the device screen, only the control command generated within the changed program screen is executed. The operation of the first output unit 100 and the first input unit 102 of the device 10 is interrupted during the remote control of the remote control device 12 as an example of the execution of the control command interruption.

The first control unit 106 according to an embodiment determines whether a control command received from the remote control device 12 via the first communication unit 104 has occurred with respect to a program approved for access. According to the discrimination result, if the control command is an instruction which is generated for a program approved for access, a control command is executed. On the other hand, if the command is for an unauthorized program, the execution of the control command is blocked.

The first controller 106 according to the embodiment transmits the device screen to the remote controller 12 through the first communication unit 104. The area other than the device screen for which the access is approved on the device screen is transmitted to the remote controller 12 12 so that they can not be displayed on the screen or can not be identified by the user of the remote control device. For example, if a device screen that is transmitted to the remote control device 12 after capture in the device 10 and displayed on the remote control device 12 is a program screen to be executed in the background of the desktop, As the desktop is shaded, the user of the remote control device can not check the contents of the desktop other than the program screen.

The user of the remote control device can check the information list displayed on the screen to see which information is accessible. The second input unit 124 receives information for remotely controlling the user from the information list.

The second control unit 126 controls each component of the remote control device 12 and remotely controls the device 10 within the information selected by the user. For example, it is possible to remotely control information that has been granted access by a device user, and remote control is not possible with respect to information whose access is blocked.

The second communication unit 120 receives a device screen for remote control from the device 10. The second output unit 122 displays the received device screen on the screen, and receives the user operation signal through the second input unit 124 on the device screen. Then, the second control unit 126 generates a control command corresponding to the inputted user operation signal, and the second communication unit 120 transmits a control command to the device 10. [ The second communication unit 120 according to an exemplary embodiment of the present invention accesses the relay server 16 to provide a remote control service to the device 10. In this case, the second communication unit 120 receives the device screen from the device 10 via the connected relay server 16, and transmits a control command to the device 10 via the relay server 16 connected thereto. The second storage unit 128 stores information necessary for remote control of the remote controller 12 and information generated during remote control.
