Computer used in an unmanned information terminal such as an Information Display). Although not shown in the drawings, one or more monitors, which are image display apparatuses, are connected to the computer 10, and the computer 10 and the monitor may be used as separate products or may be integrally formed. In addition, the computer 10 should be able to connect to a communication network 70 such as the Internet through a wired or wireless communication means.

In the embodiment of the present invention, the agent program for screen monitoring is installed on the computer 10, and the agent program acquires the screen image of the monitor connected to the computer 10 according to the set criteria and transmits it to the portable terminal 50. Do it.

The portable terminal 50 should be a terminal capable of internet access, such as a smartphone, tablet PC, and the like. In the embodiment of the present invention, the viewer program is installed in the portable terminal 50, and the viewer program transmits a monitoring request signal to the computer 10, and displays the screen image received from the computer 10 on the screen of the portable terminal 50. It serves to mark. In addition, the viewer program may include a function of transmitting and receiving a message between a plurality of users, a function of requesting and displaying an image such as a photo stored in the computer 10, and the like.

The service server 30 relays P2P communication between the computer 10 and the portable terminal 50 and stores information necessary for user authentication and screen authentication. That is, in the embodiment of the present invention, the service server 70 does not process the screen image received from the computer 10 and transmits the screen image to the portable terminal 50, but supports the role of P2P communication and the minimum service for user authentication. There is a difference from the conventional server-centric service in that it provides only.

The service server 30 includes an authentication server 32, a P2P server 34, a relay server 36, and a DB server 38, as shown in the schematic configuration diagram of FIG. Although not shown in the drawings, of course, it is provided with a control means, a storage means for operating the server.

The authentication server 32 performs procedures such as membership authentication using registered member information (ID, password, etc.), and authentication using a screen key given to a computer or a monitor.

The P2P server 34 acquires IP addresses of the computer 10 and the portable terminal 50 and transmits them to the other party, and the computer 10 and the portable terminal 50 use the IP addresses of the P2Ps to each other. Communicate.

The relay server 36 is for the case that it is difficult for the computer 10 and the portable terminal 50 to directly communicate with each other using IP addresses due to a router, a firewall, an intranet, or the like. That is, the relay server 36 has a public IP address, and relays P2P communication with each other while communicating with the computer 10 and the mobile terminal 50 using their public IP address.

Specifically, the service server 30 transmits the public IP address of the relay server 36 to the computer 10 and the portable terminal 50 when the communication through the P2P server 34 is not made, and then The computer 10 and the portable terminal 50 transmit and receive data through the relay server 36.

The DB server 38 stores information such as an ID, a password, and a screen key of a service user. Therefore, the computer 10 checks whether the input ID, password, and the like match those registered in the DB server 38, and executes the agent program only when the computer ID matches. In addition, when the screen key for the computer 10 or the monitor is registered, the computer 10 may capture and transmit the screen image only when the correct screen key is received.

In particular, FIG. 3 shows that the camera 20 is connected to the third computer 13. The camera 20 may be a webcam or a surveillance CCTV camera. Therefore, when the image of the webcam or CCTV camera is displayed on the monitor connected to the third computer 13, the portable terminal 51, 52 can check the screen image of the third computer 13 through P2P communication. In this way, if the CCTV screen can be confirmed by a large number of portable terminals (51, 52), it will be easy to solve the problem of CCTV surveillance hall due to lack of manpower.

Hereinafter, a remote screen monitoring method according to an embodiment of the present invention will be described in order with reference to FIG. 4.

First, the agent program is installed in the monitoring target computer 10 and the viewer program is installed in the portable terminal 50. The agent program can be downloaded after registration by accessing the service provider's website and the like, and the IC and password entered during the registration process are stored in the DB server 38. The viewer program can be downloaded from the App Store.

In order to execute the agent program on the monitored computer 10, a login procedure is required. The agent program transmits the input ID and password to the authentication server 32 to request authentication, and the authentication server 32 is a DB server ( The authentication process is performed using the information registered in 38).

When executing the agent program, a screen key, which is an access right for the computer 10, may be registered. When a plurality of monitors are connected to one computer 10, different screen keys may be assigned and registered for each monitor. (ST11, ST12)

When the authentication procedure is completed, the agent program of the computer 10 transmits its IP address to the service server 30, and the service server 30 registers the received IP address in the DB server 38. (ST13)

As described above, the agent program is executed in the monitored computer 10 and the remote user must execute the viewer program in the portable terminal 50 to check the screen image of the computer 10 in the state where the IP registration procedure is completed. (ST14)

The viewer program transmits the input ID and password to the authentication server 32 to request authentication, and the authentication server 32 performs the authentication procedure using the information registered in the DB server 38. When the screen key is input, the authentication server 32 may perform an authentication procedure for the screen key. However, the screen key authentication procedure may be performed in the computer 10 receiving the screen image request signal from the portable terminal 50, or the computer 10 receiving the screen image request signal may request an authentication request from the service server 30. It may be. (ST15)

When the authentication procedure is completed, the viewer program of the portable terminal 50 transmits its IP address to the service server 30, and the service server 30 registers the received IP address in the DB server 38. Alternatively, the service server 30 may register the IP address of the portable terminal 50 obtained at the authentication request after the authentication is completed in the DB server 38. (ST16)

Subsequently, the P2P server 34 of the service server 30 transmits the IP address of the computer 10 to be monitored to the portable terminal 50, and transmits the IP address of the portable terminal 50 to the computer 10. Therefore, the computer 10 and the portable terminal 50 directly communicate with each other through an IP address. (ST17, ST18)

After such communication with each other is enabled, the user can request a screen image of the monitor connected to the computer 10 by selecting the monitoring target computer 10 on the viewer program of the mobile terminal 50. In this case, when a screen key is set for the computer 10, the viewer program may display a screen key input window to input the screen key.

Meanwhile, the viewer program may provide a favorite screen including a list of the monitoring target computer 10 for the convenience of the user. The viewer program may pre-register the screen key of the monitored computer 10 or the monitor in advance when setting a bookmark.

Alternatively, as shown in FIG. 5B, a favorite screen may be provided by displaying a screen image of each computer 10 as a thumbnail image and displaying related screen information (screen name, number of users, connection status, etc.) together. . (ST19)

In any case, when the screen image request signal is transmitted from the portable terminal 50 to the computer 10, the computer 10 captures the screen image of the requested monitor and transmits the screen image to the portable terminal 50. If the screen key for the target computer 10 is set, the computer 10 checks whether the screen keys match and transmits an error signal if the screen keys do not match. Can be captured and transmitted to the portable terminal 50.

The computer 10 may capture the screen image of the monitor at predetermined intervals and continuously transmit the screen image to the portable terminal 50, and the captured screen image may be stored in the computer 10. (ST20, ST21, ST22)

On the other hand, the above has been described a case in which the computer 10 and the portable terminal 50 directly communicates through the P2P server 34, but as described above, if the direct communication through the P2P server 34 is impossible, the relay server 36 The request for the screen image and the transmission of the screen image may be made through).

Meanwhile, even when the screen request signal is received together with the screen keys from the plurality of portable terminals 50, the agent program of the computer 10 transmits the screen image to all of the plurality of portable terminals 50.

When there are a large number of users in this manner, as shown in Fig. 6, the convenience of use and enjoyment can be doubled by providing a function that allows the multiple users to send and receive messages.

This message function can be implemented in the same manner as the flowchart shown in FIG. For example, assume that viewer programs of the first portable terminal 51 and the second portable terminal 52 monitor the monitor of one computer 10. (ST31, ST34)

In this state, when the user of the first portable terminal 51 selects the 'message' menu as shown in FIG. 6, a message input window is displayed on the screen, and the message inputted through the message input window is displayed by the computer 10 by the viewer program. Is sent). (ST33)

Subsequently, the agent program of the computer 10 transmits the received message to all currently connected portable terminals 51 and 52, and the viewer program of each portable terminal 51 and 52 sends the message received from the computer 10 to the message. Display on the display. (ST36, ST35)

Subsequently, when the user of the second portable terminal 52 inputs a message through the message input window, the input message is similarly transmitted to the computer 10. (ST38) In addition, the agent program of the computer 10 transmits the received message to all connected mobile terminals 51 and 52, and the viewer program of each portable terminal 51 and 52 receives the message received from the computer 10. Is displayed in the message display window. Therefore, through this method, a plurality of monitors can monitor the monitor of the monitoring target computer 10 through their portable terminals 51 and 52, and exchange related information or send and receive messages with various people.
