The processes P1 to Pn executed in the computing device 100 can drive the window. A window driven by the process described herein may be used to display a calendar that is visually displayed on the work screen of the computing device 100 to visually (e.g., graphical user interface) display the work performed by the process Area. That is, a user of the computing device 100 may interact with the process through a window driven by the process.

According to embodiments, some of the processes P1-Pn may be able to drive the window, while others may not.

For example, as shown in Fig. 2, the first process P1 drives the first window W1, the second process P2 does not drive the window, the third process P3 does not drive the window, (W3).

The shapes of the windows W1 and W3 shown in Fig. 2 are illustrative, and the embodiments of the present invention are not limited to the window shape.

The sensing module 210A may determine whether the capture operation is performed (or started) in the computing device 100. [ The capture operation described herein refers to an operation for extracting a work screen (SCR) of the computing device 100 output by the output device 320. For example, image data corresponding to a work screen (SCR) may be generated according to the capture operation.

According to embodiments, the capture operation may be performed by the screen capture program 133 running on the computing device 100, but is not so limited. For example, the capture operation may be performed by the operating system 131.

The detection module 210A monitors the processes P1 to Pn executed in the computing device 100 and can check what operations are performed by the processes P1 to Pn.

The detection module 210A accesses a memory area (e.g., a memory area where each of the processes P1 to Pn is loaded) of each of the processes P1 to Pn executed in the computing device 100, (E. G., Function calls) performed by the processes P1 through Pn depending on the result.

According to embodiments, the sensing module 210A may monitor processes P1 through Pn running on the computing device 100 using API hooking.

For example, the watermark deactivation program 200 is injected into the memory areas of the processes P1 to Pn when the processes P1 to Pn are executed in the computing device 100 and is executed by the processes P1 to Pn You can monitor the tasks that are being performed. For example, the watermark deactivation program 200 may be implemented as a dynamic link library (DLL) file and inserted so that it is automatically loaded by the process as the processes P1 to Pn are executed.

The sensing module 210A may sense whether the capture operation is performed in the computing device 100 according to the result of the monitoring. According to embodiments, the sensing module 210A may identify a process (e.g., the capture process (CP) of FIG. 2) that performs the capture operation among the processes P1-Pn.

The sensing module 210A determines whether a work pattern or a task pattern of each of the processes P1 to Pn coincides with a capture pattern that appears when a capture operation is performed, and if the operation pattern matches the capture pattern (Or judged) that the capture operation is performed. At this time, it is possible to identify a process showing a work pattern matching the capture pattern, that is, a process of performing a capture operation, as a capture process (CP).

The job pattern of the processes P1 to Pn may mean a function to be called by the processes P1 to Pn. That is, the detection module 210A determines whether a function called by each of the processes P1 to Pn executed in the computing device 100 is a capture function used for a capture operation, Function, it can be determined that the capture operation is performed.

The capture pattern may be predefined and stored or updated. According to embodiments, a list (or a configuration file) that can reference (or contain) the capture pattern may be stored in the computing device 100, and the sensing module 210A may refer to the stored list, Can be performed.

On the other hand, the coincidence between the operation pattern and the capture pattern includes that the operation pattern and the capture pattern match within an error range (for example, allowed by the detection module 210A).

The detection module 210A may stop (or suspend) the capture operation. In accordance with embodiments, the sensing module 210A may control the capture process (CP) such that the capture operation is stopped.

According to embodiments, the detection module 210A may prevent a response (i.e., a capture function) in response to the call to be delivered to the capture process (CP) when the capture process (CP) calls the capture function.

The identification module 220A determines whether or not the processes P1 through Pn executed in the computing device 100 are performed when the capture operation is determined to be performed (or started) in the computing device 100 according to the determination of the sensing module 210A. (P3 or WP) that displays a watermark on the working screen of the computing device 100. [0050]

The identification module 220A obtains the transparency of each of the windows driven by each of the processes P1 to Pn when the capture operation is started at the computing device 100 and generates the processes P1 ≪ / RTI > Pn). ≪ / RTI >

In accordance with embodiments, the identification module 220A may identify, among the processes P1-Pn, a process having a semitransparent window as a watermark process (WP) when a capture operation is initiated at the computing device 100 .

Generally, the watermark process (WP) displaying the watermark (WM) on the work screen (SCR) often has a translucent window, so that the identification module 220A can identify the processes Based on the transparency of each of the driven windows, the watermark process can be identified among the processes P1 to Pn.

The control module 230A may disable or deactivate the watermark process WP. According to embodiments, the control module 230A may deactivate the watermark process (WP) before the capture operation performed on the computing device 100 is complete.

The completion time of the capture operation described herein is determined by information about the operation screen (SCR) of the computing device 100 by a function called by the capture process (CP) or the capture process (CP) (Or information on the window displayed on the work screen SCR) is collected (or acquired).

As described above, since the sensing module 210A can stop the capturing operation performed by the capturing process CP, the control module 230A can control the operation of the computing device 100 before the capturing operation performed in the computing device 100 is completed, The mark process (WP) can be deactivated.

In addition, the deactivation of the watermark process (WP) described herein means all the functions of controlling the watermark process (WP) so that the watermark (WM) displayed by the watermark process (WP) . For example, the control module 230A,

(1) The watermark process (WP) is controlled so that the watermark (WM) displayed by the watermark process (WP) or the window driven by the watermark process (WP) becomes transparent,

(2) terminating or stopping the watermarking process (WP), or

(3) By hiding the window driven by the watermarking process (WP), the watermarking process (WP) can be deactivated, but is not limited thereto.

The control module 230A may resume the capture operation performed by the capture process CP after the watermark process WP is deactivated.

After the capture operation is resumed, the control module 230A can determine whether the deactivation of the watermark process (WP) has been normally performed.

According to the embodiments, when the capture process CP has collected information about the SCR of the computing device 100, the control module 230A determines whether the information of the watermark process (WP) It can be judged whether or not it is included.

When information on the watermark process (WP) is included in the collected information, since the deactivation of the watermark process (WP) has not been normally performed, the control module 230A can terminate the capture operation. When information on the watermark process (WP) is not included in the collected information, since the watermark process (WP) is inactivated normally, the control module 230A may not perform a separate operation.

The control module 230A may enable or activate the watermark process WP after the capture operation of the capture process CP is completed.

The control module 230A may activate the watermark process WP when the capture process CP has collected information about the SCR of the computing device 100. [ According to embodiments, the control module 230A accesses the memory area of the capture process CP identified by the capture module 210A and, depending on the result of the access, the capture process (CP) It is possible to judge whether or not the information has been collected, and activate the watermark process (WP) according to the result of the judgment.

Activation of the watermark process (WP) described herein refers to all the functions of controlling the deactivated watermark process (WP) such that the watermark (WM) that is not visible to the computing device (100) is displayed again. For example, the control module 230A,

(1) The watermark process (WP) is controlled so that the watermark (WM) displayed by the watermark process (WP) or the window driven by the watermark process (WP) becomes translucent,

(2) start (or execute) a watermark process (WP) that has been paused (or terminated), or

(3) By revealing the window driven by the watermarking process WP, it is possible to activate the watermarking process WP, but this is not restrictive.

The authentication module 240A receives the user information UINFO and transmits the input user information UINFO to the server 400. [ According to embodiments, the user information UINFO may include an identification (ID) and a password.

 The authentication module 240A receives the authentication result AUT sent from the server 400 and can control the operation of the remaining modules 210A, 220A, and 230A according to the authentication result AUT.

According to embodiments, when the authentication result AUT sent from the server 400 indicates that the user information UINFO has been authenticated, the authentication module 240A may activate the remaining modules 210A, 220A, and 230A have. When the authentication result AUT sent from the server 400 indicates that the user information UINFO has not been authenticated, the authentication module 240A may deactivate the remaining modules 210A, 220A, and 230A.

Therefore, only when the user of the computing device 100 is an authenticated user, the watermark deactivation program 200 can be normally operated and automatically deactivate the watermark process (WP) before the capture operation is completed.

According to the watermark deactivation program 200 according to the embodiments of the present invention, the watermark process WP is deactivated until the capture operation is started and completed. Therefore, the capture operation can be performed when the watermark process WP is deactivated, so that the watermark WM is added to the image data generated by the capture operation (i.e., the image data representing the work screen SCR) May not be displayed.

The capture module 240B may generate image data representing a work screen (SCR) using the information related to the work screen (SCR) of the acquired computing device 100. [

The authentication module 250B receives the user information UINFO and transmits the input user information UINFO to the server 400 and receives the authentication result AUT transmitted from the server 400 and transmits the authentication result AUT, the operation of the remaining modules 210B, 220B, 230B, and 240B.

Since the control operation of the authentication module 250B is the same as the control operation of the authentication module 240A shown in Fig. 3, the description will be omitted.
