Determines whether to convert an electronic document (or an electronic document in the process of being created), a still image, or a moving picture) created by the user to another image or to keep it as it is.

For example, when the operation mode information MI defines (or indicates) the shooting attempt prevention mode, the screen change control module 240 may detect a shooting attempt detection result (or a first detection result) and/or a device separation detection result (or the second detection result), the image currently displayed on the monitor 180-1 is switched to another image.

However, when the operation mode information MI defines (or indicates) the violation detection mode, the screen change control module 240 controls the monitor 180-1 even if the shooting attempt detection result and/or device separation detection result are input. Keeps the currently displayed image in .

The log module 250, in response to the capture attempt detection result and/or the device disconnection detection result, is configured to include an IP address of the first user computer 170-1, a MAC address of the first user computer 170-1, and a monitor ( 180-1), a picture taken by an illegal photographer who attempted to take a picture on the monitor 180-1, and/or an image captured by the illegal photographer (ie, an image displayed on the monitor 180-1) or an electronic document), which creates a violation log (ILL) containing a photograph of it.

The photo of the illegal photographer (ie, evidence photo) may be a photo taken by the camera 177 - 1 and/or the camera 195 . For example, even if the illegal photographer disables or removes any one of the cameras 177-1 and 195, the other one of the cameras 177-1 and 195 tracks the movement of the illegal photographer to see the illegal photographer's face. can be taken as evidence.

The photo taken by the illegal photographer takes the image (or electronic document) taken by the illegal photographer using his/her capture camera. In response to the detection result of the shooting attempt and/or the detection result of device disconnection, the screen capture program may be controlled to capture the image captured by the illegal photographer using the capture camera. According to embodiments, the computer program 200 may provide a screen capture function.

When the violation log ILL can be immediately transmitted to the server 150 , the log module 250 immediately transmits the violation log ILL to the server 150 through the first cable 152 and the communication network 150 , , the server 150 may transmit the received violation log ILL to the administrator computer 110 .

FIG. 3 is a flowchart for explaining the operation of the computer program shown in FIG. 2 . 2 and 3 , the administrator sets the operation mode information MI through the administrator computer 110 . For convenience of explanation, when the operation mode information MI is set to a first value (eg, '0'), the operation mode information MI indicates a photographing attempt prevention mode, and the operation mode information MI is It is assumed that when set to a second value (eg, '1'), the operation mode information MI indicates a violation detection mode.

When the administrator sets the operation mode information MI to the first value through the administrator computer 110, the server 130 receives and stores the operation mode information MI set as the first value (S110).

When the first user computer 170-1 is powered-up (booting or standby state in which the computer program 200-1 can be executed) (S115), the computer program 200-1 is operated from the server 130 It is determined whether the information MI can be read (S120).

When the computer program 200-1 cannot read the operation mode information MI from the server 130 within a predetermined time (NO in S120), for example, the first user computer 170-1 and the server 130 ), when smooth communication is not possible, the computer program 200-1 performs a default mode set as a default. For example, the computer program 200-1 includes a function to determine the elapse of a predetermined time, and the administrator can set the predetermined time to the server 130 using the administrator computer 110, and the server The predetermined time set in 130 may be transmitted to the computer program 200-1.

In this case, it is assumed that the default mode is a photographing attempt prevention mode. In the shooting attempt prevention mode, the image (or electronic document) requiring security is blocked from being displayed on the monitor 180-1, or the image (or electronic document) requiring security is displayed in another image (or other electronic document) that does not require security. document), so that the video (or electronic document) requiring security can be prevented from being illegally leaked.

When smooth communication between the first user computer 170-1 and the server 130, which will be described below, is not possible (NO in S135, NO in S147, and NO in S157), the first user computer 170-1 ) and the communication network 150 are not smoothly connected, the first cable 152 is out of order, or the first cable 152 (for example, a LAN cable) is disconnected from the first user computer 170-1. In case of intentional separation (that is, when an illegal photographer disconnects the first cable 152 from the first user computer 170-1 to illegally capture the image currently displayed on the monitor 180-1) include

When the screen change control module 240 of the computer program 200-1 can read the operation mode information MI from the server 130 within a predetermined time (YES in S120), the computer program 200-1 The screen change control module 240 reads the operation mode information MI from the server 130 (S125).

The screen change control module 240 of the computer program 200 - 1 determines whether the mode to be performed is the shooting attempt prevention mode based on the value corresponding to the operation mode information MI ( S130 ).

As previously assumed, since the operation mode information MI is set to the first value (YES in S130), the screen change control module 240 of the computer program 200-1 may perform the shooting attempt prevention mode. .

The computer program 200 - 1 detects a photographing attempt using the photographing attempt detection module 220 , and detects device separation using the device separation detection module 230 ( S140 ).

The screen switching control module 240 of the computer program 200-1 monitors ( 180-1) blocks the currently displayed image or switches to another image (S150). Accordingly, the image that is the target of illegal recording is blocked or replaced with another image.

4 is a warning screen displayed on a display device of a computer in a photographing attempt prevention mode. The screen change control module 240 may generate a warning screen GUI1 and transmit it to the monitor 180 - 1 as an example of blocking the image currently displayed on the monitor 180 - 1 or switching to another image. The warning screen GUI1 may display a warning message and the date and time at which the shooting was attempted.

According to embodiments, the screen change control module 240 causes the word processor that transmits the image (or document) to the monitor 180-1 to stop the word processor, block transmission of the image (or document), or A screen for displaying the image may be minimized.

The log module 250 of the computer program 200 - 1 responds to the detection of the imaging attempt by the imaging attempt detection module 220 and/or the detection of the device disconnection by the device disconnection detection module 230 , the above-described violation log. (ILL) is generated, and the generated violation log (ILL) is transmitted to the server 130 through the interface 175-1, the first cable 152, and the communication network 150 (S160).

For example, the screen change operation of the screen change control module 240 and the violation log generation operation of the log module 250 may be simultaneously performed.

When the administrator sets the operation mode information MI to a second value (eg, 1) through the administrator computer 110, the server 130 stores the operation mode information MI set to the second value ( S110).

When the first user computer 170-1 is powered up (or in a standby state in which the computer program 200-1 can be executed) (S115), the computer program 200-1 receives operation mode information from the server 130 It is determined whether (MI) can be read (S120).

When the computer program 200-1 cannot read the operation mode information MI from the server 130 within a predetermined time (NO in S120), for example, the first user computer 170-1 and the server 130 ) cannot perform smooth communication, the computer program 200-1 forcibly executes the default mode instead of performing the violation detection mode.

When the computer program 200-1 can read the operation mode information MI from the server 130 within a predetermined time (YES in S120), the computer program 200-1 provides the operation mode information from the server 130 (MI) is read (S125).

The computer program 200 - 1 determines whether the mode to be performed is the photographing attempt prevention mode based on the operation mode information MI ( S130 ).

As previously assumed, since the operation mode information MI is set to the second value (NO in S130), the computer program 200-1 may perform the violation detection mode.

If smooth communication is not possible between the server 130 and the first user computer 170-1 (NO in S135), the computer program 200-1 attempts shooting from the violation detection mode corresponding to the second value. Forcibly switches to prevent mode.

If smooth communication is possible between the server 130 and the first user computer 170-1 (YES in S135), the computer program 200-1 detects the shooting attempt using the shooting attempt detection module 220 and , the device separation is detected using the device separation detection module 230 (S145).

If smooth communication is not possible between the server 130 and the first user computer 170-1 (NO in S137), the computer program 200-1 changes the set operation mode from the violation detection mode to the shooting attempt prevention mode. to forcibly switch to Accordingly, the screen change control module 240 of the computer program 200 - 1 responds to the detection of the photographing attempt by the photographing attempt detection module 220 and/or the detection of the device separation by the device separation detection module 230 . The image currently displayed on the monitor 180-1 is blocked or switched to another image (S150).

When smooth communication is possible between the server 130 and the first user computer 170-1 (YES in S137), the screen change control module 240 of the computer program 200-1 is displayed on the monitor 180-1. The currently displayed image is maintained without blocking or switching to another image (S155).

The log module 250 of the computer program 200 - 1 responds to the detection of the imaging attempt by the imaging attempt detection module 220 and/or the detection of the device disconnection by the device disconnection detection module 230 , the violation log (ILL). ) is created.

If smooth communication is not possible between the server 130 and the first user computer 170-1 (NO in S177), the log module 250 of the computer program 200-1 generates a generated violation log (ILL). cannot be directly transmitted to the server 130, so the computer program 200-1 generates a violation log ILL and stores it in the memory 173-1 until smooth communication with the server 130 is possible (S159) .

When smooth communication is possible between the server 130 and the first user computer 170-1 (YES in S177), the log module 250 of the computer program 200-1 generates the generated violation log ILL or memory. The violation log (ILL) stored in (173-1) is transmitted to the server 130 through the interface (175-1), the first cable (152), and the communication network (150) (S165).
