Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view for explaining a personal computer interfacing with a portable terminal in an instant messaging service system according to an embodiment of the present invention.

1, an instant message service system according to an embodiment of the present invention includes a personal computer 110, a portable terminal 120, an instant message server 130, and a push server 140 do. The portable terminal 120 according to an embodiment of the present invention includes a smart phone.

Basically, the user can access the instant message server 130 using an application installed in the portable terminal 120. [ The instant message server 130 may process the user's request (e.g., chat room creation, text message transmission, friend invitation, etc.) through the application and respond to the application with the result.

In this case, the instant message server 130 may request the push providing server 140 for the push providing service. The push providing server 140 may transmit a push signal to the application installed in the portable terminal 120 of the user in response to the request.

The user can control the application installed in the portable terminal 120 in the personal computer 110 by linking the personal computer 110 and the portable terminal 120 according to an embodiment of the present invention. For example, a user can use various services that the application requests to the instant message server 130 through an interface provided in the personal computer 110. [ In addition, the user can use the information stored in the application through the interface provided in the personal computer 110. [

More specifically, the user can view the current chatting room list, select one chat room from among the displayed chat room lists, view the conversation history in the selected chat room, and send an instant message such as a text message in the selected chat room The service can be directly controlled from the personal computer 110. In this case, communication may be performed between the portable terminal 120 and the instant message server 130 due to the operation of the personal computer 110, thereby changing the chat room in the instant message server 130 or the like .

Further, the application may transmit the push signal transmitted from the push providing server 140 to the personal computer 110. [ In this case, the user can confirm the fact that the application receives the push signal through the interface of the personal computer 110 without directly checking the portable terminal 120.

(For example, TCP / IP connection and pairing) between the personal computer 110 and the application according to an embodiment of the present invention, an operation method of the personal computer 110, and an operation method of the application Will be described later in detail with reference to Figs. 2 to 4. Fig.

2 to 3 are views for explaining operations of a personal computer for controlling an application installed in a portable terminal in an instant message service system according to an embodiment of the present invention.

Referring to FIG. 2, a personal computer according to an exemplary embodiment of the present invention provides an interface 210 for receiving a plurality of actions for controlling an application installed in a portable terminal. The personal computer receives at least one action among the plurality of actions through the interface (220).

Here, the plurality of actions include an action of transmitting at least one of a text message, image data, or moving picture data. Further, the plurality of actions may further include at least one of an action for inquiring a chat room list, an action for selecting one of the chat rooms, or an action for inquiring a conversation history in the selected chat room.

The interface may be provided in various forms according to the UI that the personal computer can support. For example, a personal computer is an interface for an action for inquiring a chat room list, and can provide a button called "chat room list inquiry" in response to a mouse left click. Alternatively, the personal computer is an interface for an action that queries a chat room list, and can provide a shortcut key (e.g., Ctrl + R).

At this time, the user can simultaneously input two or more actions using the interface. For example, when a user selects one chat room from the list of chat rooms, it is necessary to inquire the conversation history in the selected chat room at the same time as entering the selected chat room. Accordingly, when the user selects one chat room from the list of chat rooms displayed by using the interface provided by the personal computer, it can be seen that the user inputs both the action of selecting the chat room and the action of inquiring the conversation history in the selected chat room .

That is, according to an embodiment of the present invention, a user can control the application using an interface provided by a personal computer instead of directly using the portable terminal.

The personal computer also generates a control signal corresponding to at least one action entered by the user (230). Here, the control signal includes an encrypted query signal for security. According to one embodiment of the present invention, the control signal may be encrypted using a known symmetric key algorithm (e.g., AES) or an asymmetric key algorithm (e.g., RSA, etc.).

Further, the personal computer transmits the control signal to the application installed in the portable terminal (240).

According to an embodiment of the present invention, an application installed in the portable terminal may be an instant message service application (hereinafter referred to as an IMS application).

The IMS application receives the control signal transmitted by the personal computer and determines an instant messaging service corresponding to the control signal (250).

In this case, the instant message service corresponding to the control signal may be a service for transmitting at least one of a text message, image data, and moving picture data, a service for inquiring a chat room list, a service for selecting one of the chat rooms, And a service for inquiring the conversation history in the selected chat room.

The IMS application determines whether it has data for performing the determined service (260). For example, if the instant messaging service corresponding to the control signal is a service inquiring a chat room list, the IMS application may determine whether the instant messaging server has data related to the chat room list before requesting the service .

In this case, the IMS application according to an embodiment of the present invention can store data related to various settings of the IMS application. For example, it is possible to store data related to an image file to be used as a background screen of each of a plurality of chat rooms that the current user is entering, and can set the notification settings (whether or not push notifications are permitted, Lt; / RTI >

The IMS application can perform the service without requesting the instant message server according to the determination that it has data for performing the determined service (270).

Further, the IMS application may generate a response signal to the control signal transmitted from the personal computer in response to the execution of the determined service (280), and may transmit the generated response signal to the personal computer (285).

In addition, the IMS application may request the determined instant messaging server to the instant messaging server according to the determination that the instant messaging server does not have data for performing the determined service (261). In this case, the instant message server processes the requested service and responds to the IMS application (262).

In this case, the IMS application may receive a response signal to the request and generate a response signal to the control signal received from the personal computer based on the received response signal (280). The IMS application may use the received response signal as a response signal to the control signal as it is. The IMS application then sends the generated response signal to the personal computer (285).

Here, the response signal includes an encrypted query signal for security as well as the control signal, and the response signal may be a symmetric key algorithm (for example, AES) or an asymmetric key algorithm (for example, RSA Etc.). ≪ / RTI >

The personal computer receives the response signal transmitted by the IMS application and displays information corresponding to the response signal on the display included in the personal computer (290).

For example, suppose that a user enters an action to view a list of currently entered chat rooms using the interface provided by the personal computer. The personal computer generates a control signal for the chat room list inquiry action and transmits it to the IMS application. The IMS application needs to perform a service for inquiring the list of currently entered chat rooms based on the control signal transmitted from the personal computer.

The IMS application determines whether it has data for executing the chat room list inquiry service. If the IMS application does not have data for performing the chat room list inquiry service, the IMS application requests the chat room list inquiry service to the instant message server and receives the result. The IMS application generates a response signal based on the result, and transmits the generated response signal to the personal computer. The personal computer can display a list of currently entered chat rooms on the display based on the response signal transmitted from the IMS application.

The user can select any of the displayed chat room lists using the interface provided by the personal computer. In this case, as described above, the personal computer can generate a control signal including an action for selecting a chat room and an action for inquiring a conversation history of the selected chat room, and then transmit the control signal to the IMS application. It can be seen that the IMS application must perform a service of selecting a chat room first based on a control signal transmitted from a personal computer.

At this time, since the IMS application has received the result of requesting the chat room list inquiry service to the instant message server, the IMS application has data related to the chat room list. Further, the IMS application may have configuration data associated with the selected chat room (e.g., an image file used as the background screen of the selected chat room). In this case, the IMS application can perform the chat room selection service without having to request the service to the instant message server. The IMS application can switch the screen to the selected chat room using the image file and include the image file in the response signal to the personal computer.

Then, the personal computer can know that a service for inquiring the conversation history in the selected chat room should be performed in the action. Likewise, the IMS application determines whether it has data about the conversation history in the selected chat room.

If the IMS application does not have data for the conversation history in the selected chat room, the IMS application requests the chat message list of the selected chat room to the instant message server. The instant message server inquires the chat message list according to the request and returns the result to the IMS application. The IMS application generates a response signal based on the result, and transmits the generated response signal to the personal computer. The personal computer can display a chat message list of the chat room selected by the user on the display based on the response signal transmitted from the IMS application.

On the other hand, the control signal generated by the personal computer is a control signal corresponding to an action of transmitting at least one of a keyboard input or a pointing input (for example, movement of a mouse cursor, mouse click, touch of a touch pad, drag, have.

In this case, the IMS application may further include determining whether the control signal received from the personal computer is at least one of a keyboard input and a pointing input (not shown). The IMS application may process the keyboard input or the pointing input according to the determination that the control signal is at least one of a keyboard input and a pointing input.

For example, if the control signal corresponds to an action for transmitting a keyboard input, the IMS application may transmit the keyboard input character or string as a text message. In addition, when the keyboard input corresponds to a predetermined shortcut key, an operation corresponding to the shortcut key may be performed.

Further, when the control signal corresponds to an action of transmitting a pointing input, the IMS application may perform an operation corresponding to the pointing input. At this time, the IMS application can expose a separate mouse cursor to the application screen.

Referring to FIG. 3, an instant message server according to an embodiment of the present invention may request a push providing service to a push providing server (310). The push providing server transmits a push signal to the IMS application in response to the request (320).

The IMS application transmits the received push signal to the personal computer (330). Here, the IMS application according to another embodiment of the present invention can convert the push signal into a predetermined data structure instead of transmitting the push signal as it is. At this time, the data structure can be encrypted for security. The data structure may be encrypted using a known symmetric key algorithm (e.g., AES, etc.) or an asymmetric key algorithm (e.g., RSA, etc.).

The personal computer receives the push signal transmitted by the IMS application and displays the corresponding information on the display (340). Accordingly, the user can confirm whether or not a new message has been received through the information provided by the personal computer without directly checking the portable terminal.

4 is a diagram for explaining a pairing operation between a portable terminal and a personal computer in an instant messaging service system according to an embodiment of the present invention.

Referring to FIG. 4, the personal computer and the IMS application according to an embodiment of the present invention can be connected using a client-server method.

The IMS application prepares a TCP / IP socket server to allow the personal computer to access (411). The personal computer makes a TCP / IP connection to the socket server (412). Here, the IMS application and the personal computer can perform TCP / IP communication using a predetermined port number (for example, 8080).

That is, the personal computer scans to the predetermined port number, and the user can use the personal computer to select a socket server provided by the IMS application among at least one scan result. Accordingly, the personal computer makes a TCP / IP connection to the IMS application preparing the selected socket server.

According to an embodiment of the present invention, a first IMS application installed in a first terminal prepares a first TCP / IP socket server, and a second IMS application installed in a second terminal prepares a second TCP / IP socket server have. Here, the first TCP / IP socket server and the second TPC / IP socket server are different TCP / IP socket servers.

At this time, the first TCP / IP socket server and the second TCP / IP socket server can use the same port number (for example, 8080) for communication with the personal computer. In this case, when the personal computer scans the corresponding port number, both the first TCP / IP socket server and the second TCP / IP socket server are searched.

The personal computer can display the ID of the terminal corresponding to each searched server, the unique name of the terminal, or the name or application ID of the IMS application installed in the terminal on a display included in the personal computer.

The user can connect to the IMS application prepared for the selected socket server by selecting one of the first TCP / IP socket server and the second TCP / IP socket server which are searched for using the personal computer for TCP / IP connection.

According to another embodiment of the present invention, a user selects a TCP / IP socket server that is not currently connected among the first TCP / IP socket server and the second TCP / IP socket server found by using the personal computer, Lt; RTI ID = 0.0 > IMS < / RTI >

For example, assume that the personal computer is connected to the first IMS application. Even if the personal computer is connected to the first IMS application, when a scan is performed with a predetermined port number (for example, a port number commonly used by the first TCP / IP socket server and the second TCP / IP socket server) Both the TCP / IP socket server and the second TCP / IP socket server are searched.

At this time, if the user selects the second IMS application using the personal computer, the personal computer can disconnect the first IMS application that has been previously connected and access the newly selected second IMS application.

After socket connection, personal computer and IMS application communicate with each other with encrypted data for security. The encrypted data may be encrypted using a known symmetric key algorithm (e.g., AES) or an asymmetric key algorithm (e.g., RSA, etc.).

In addition, the IMS application displays an authentication key on the display included in the portable terminal for pairing with the personal computer (421). Here, the IMS application may change the authentication key displayed on the display for a predetermined time (for example, one minute) to increase the security level.

The user inputs the displayed authentication key into the personal computer (422). The personal computer encrypts the unique name of the personal computer using the authentication key input by the user (423). At this time, the personal computer can encrypt the distinguished name according to the hash-based message authentication code (HMAC) authentication method.

The personal computer transmits the unique name of the encrypted personal computer to the IMS application (424). The IMS application decrypts the unique name of the encrypted personal computer transmitted using the authentication key displayed on the display (425). At this time, the IMS application can confirm the distinguished name according to the hash-based message authentication code (HMAC) authentication method.

The personal computer displays the decrypted personal computer's unique name on the display included in the portable terminal (426). The user can confirm whether or not the displayed distinguished name is a unique name of the personal computer. When the confirmation is completed, the user inputs that the pairing has been confirmed to the personal computer (427). The personal computer notifies the IMS application that the pairing has been successful (428) by sending a pairing confirmation signal to the IMS application.

The IMS application can generate a security key for communication between the IMS application and the personal computer (e.g., sending and receiving control signals and response signals) upon receipt of a signal indicating that the pairing has been successfully performed 431). The security key according to an exemplary embodiment of the present invention may include a session key and a secret key. The IMS application may send the generated secret key to the personal computer that has successfully been paired (432).

5 is a diagram illustrating a repair operation between a portable terminal and a personal computer in an instant message service system according to an embodiment of the present invention.

Referring to FIG. 5, the personal computer and the IMS application according to an embodiment of the present invention store the pairing information that has been successfully performed, and can perform the repair without performing the authentication process again using the information.

When the pairing is successfully performed, the IMS application can transmit a unique ID (e.g., terminal ID) of the portable terminal installed therein to the personal computer (520). The personal computer may send its unique ID (e.g., personal computer ID) to the IMS application (510).

At this time, according to another embodiment of the present invention, the IMS application can transmit the terminal ID to the personal computer in response to the port scan of the personal computer. As described above, the IMS application prepares 411 a TCP / IP socket server. When the personal computer performs port scanning using a predetermined port number, the TCP / IP socket server prepared by the IMS application is searched. Here, the terminal ID may be included in the information about the searched TCP / IP socket server.

Further, according to another embodiment of the present invention, the personal computer may transmit the personal computer ID together when transmitting (428) the pairing confirmation signal to the IMS application.

The IMS application may map the personal computer ID to the security key 431 generated for use in communication between the IMS application and the personal computer (e.g., sending / receiving control signals and response signals) (511 ). The IMS application may use 512 for later repairing operations by storing the mapping results (512).

The personal computer may map the terminal ID to the security key 432 received from the IMS application (521). The personal computer can then use the mapping results (522) for later repair operations.

Meanwhile, the personal computer according to an embodiment of the present invention may determine whether to perform the repair using the stored mapping result after performing the TCP / IP connection 412 to the IMS application. That is, if the terminal ID of the target IMS application that made the TCP / IP connection exists in the stored mapping result, the personal computer can repair the IMS application. In this case, the authentication step and the security key generation step may be skipped during the pairing operation, and mutual communication may be performed using the security keys previously created and included in the stored mapping result.

In addition, the personal computer according to another embodiment of the present invention automatically transmits a port (for example, 30 seconds) for repair at a predetermined period (for example, 30 seconds) in a predetermined condition (for example, Scan may be performed (531).

The personal computer receives the terminal ID of the portable terminal retrieved as a result of the port scan (532). The personal computer can determine whether to perform repair with the portable terminal corresponding to the received terminal ID using the received terminal ID and the stored mapping result (533). If the received terminal ID is present in the stored mapping result, the personal computer can make a repair request to the portable terminal (534).

According to one embodiment of the present invention, the data for the repair request of the personal computer may include a time stamp, a personal computer ID, and a terminal ID. Here, the time stamp is a time point at which the personal computer transmits data for a repair request to the IMS application. The IMS application can check the time stamp in the received repair request data and recognize only data within a predetermined time (for example, 10 minutes) from the transmitted time as normal data. That is, when receiving the data whose elapsing time (for example, 10 minutes) has elapsed from the transmission point of time, the received data can be discarded without performing the repair.

Further, the personal computer may send a hash-based message authentication code (HMAC) generated based on the data and the secret key to the IMS application upon a repair request. The IMS application may generate a hash-based message authentication code (HMAC) of the received data using a secret key corresponding to the personal computer ID in the received data. The IMS application can verify the security key corresponding to the personal computer ID by comparing the generated HMAC with the received HMAC.

When the repair is successfully performed, the IMS application and the personal computer can exchange encrypted data using the stored security key, respectively.

The methods according to embodiments of the present invention may be implemented in the form of program instructions that can be executed through various computer means and recorded in a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination. The program instructions recorded on the medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.
