Abstract
Description
Technical Field
[0001] The present application relates to the field of display technology, and in particular to a method, device, equipment and computer-readable storage medium for adding watermarks to application windows. Background Art
[0002] The lack of a watermark mechanism for sensitive information displayed in certain application windows (such as sensitive text, graphics, and videos in application windows) may lead to the leakage of sensitive information, making it impossible to trace the source.
[0003] Currently, there are three main methods for adding watermarks to application windows. One is to obtain a watermarked web page based on World Wide Web (web) technology, and add watermarks by browser display or web container display. Another is full-screen watermarking, which is too bloated for lightweight watermark protection. Another is to inject the target execution code into the startup thread based on hook technology. After the injection is successful, the target view display function with the watermark is used to replace the original view display function to achieve the watermarking effect.
[0004] However, the above three watermarking methods all have certain disadvantages. First, the watermarking method based on web technology requires a lot of pre-coding and the support of corresponding framework technology, which requires a lot of personnel and technical costs. Secondly, the full-screen watermarking method is too heavy in terms of human-computer interaction and display effects. Moreover, injection is an invasive attack method that will cause unknown errors to the application itself, with high security risks and low execution efficiency.
[0005] To sum up, how to effectively solve the problems of high investment in personnel and technical costs, excessive human-computer interaction and display effects, high security risks, and low execution efficiency is an issue that technical personnel in this field urgently need to solve. Summary of the invention

[0052] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.
[0053] See also Figure 1 , Figure 1 This is a flowchart of an implementation method of adding a watermark to an application window in an embodiment of the present application. The method may include the following steps:
[0054] S101: Acquire a target application window to which a watermark is to be added.
[0055] Get the target application window to which the watermark is to be added.
[0056] The target application window may be any application window to which a watermark is to be added, such as a document (word) window, a browser viewing window, a picture viewing window, and the like.
[0057] S102: calling a watermark interface to obtain a target handle corresponding to a target application window, and obtaining watermark parameters input from the watermark interface.
[0058] The handles (hwnd) of commonly used application windows can be collected and stored in advance. After obtaining the target application window to be watermarked, the watermark interface is called to obtain the target handle corresponding to the target application window, and the watermark parameters input from the watermark interface are obtained.
[0059] Watermark parameters may include font size, tilt, display content, etc.
[0060] S103: embedding an initial watermark window into the target application window according to the target handle.
[0061] After obtaining the target handle corresponding to the target application window, the initial watermark window is embedded into the target application window according to the target handle, thereby realizing the binding of the target application window with the initial watermark window.
[0062] S104: Drawing a target graphic canvas to the initial watermark window according to the watermark parameters, so that the target application window displays the watermark information according to the target graphic canvas.
[0063] After the initial watermark window is embedded in the target application window, the target graphic canvas is drawn to the initial watermark window according to the watermark parameters, so that the target application window displays the watermark information according to the target graphic canvas.
[0064] It can be seen from the above technical solution that by obtaining the target handle corresponding to the target application window to be watermarked, the initial watermark window is embedded into the target application window according to the target handle, without the need for complex frameworks and a large amount of coding, thereby realizing the binding of the initial watermark window with the target application window, which greatly reduces the cost. The initial watermark window will only be embedded on the target application window and will not affect other windows. Compared with the full-screen watermark, it is more lightweight. At the same time, this application embeds a watermark layer on the target application window, which reduces security risks and improves execution efficiency compared to injection technology.
[0065] It should be noted that, based on the above embodiments, the embodiments of the present application also provide corresponding improved solutions. In the subsequent embodiments, the same steps or corresponding steps as those in the above embodiments can be referenced to each other, and the corresponding beneficial effects can also be referenced to each other, which will not be repeated one by one in the following improved embodiments.
[0066] See also Figure 2 , Figure 2 This is another implementation flow chart of the method for adding a watermark to an application window in an embodiment of the present application. The method may include the following steps:
[0067] S201: Acquire the target application window to which a watermark is to be added.
[0068] S202: Call the watermark software development kit to open the watermark interface.
[0069] A watermark software development kit is pre-set to control the opening and closing of the watermark interface. After obtaining the target application window to be watermarked, the watermark software development kit (SDK) is called to open the watermark interface.
[0070] S203: Obtain the target handle corresponding to the target application window from the handle library through the watermark interface, and obtain the watermark parameters input from the watermark interface.
[0071] The handle library stores the corresponding relationship between each application window and each handle.
[0072] A handle library storing the correspondence between each application window and each handle is pre-set. After calling the watermark software development kit to open the watermark interface, the target handle corresponding to the target application window is obtained from the handle library through the watermark interface, and the watermark parameters input from the watermark interface are obtained.
[0073] S204: Embedding an initial watermark window into the target application window according to the target handle.
[0074] S205: Determine whether the watermark parameters are valid, if not, execute step S206, if yes, execute step S207.
[0075] After obtaining the watermark parameters, determine whether the watermark parameters are valid. If not, it means that the watermark parameter setting has failed, and the subsequent process of adding a watermark to the target application window cannot be performed according to the currently set watermark parameters. Execute step S206. If so, it means that the subsequent process of adding a watermark to the target application window can be performed according to the currently set watermark parameters. Execute step S207.
[0076] The method of judging whether the watermark parameters are valid may include judging whether the character type contained in the watermark parameters is the set character type allowed to be input, and may also judge whether the number of parameters input is the set number of parameters required to be input.
[0077] S206: End the process of adding a watermark to the target application window.
[0078] When it is determined that the watermark parameters are invalid, it means that the watermark parameter setting fails, and the subsequent process of adding a watermark to the target application window cannot be performed according to the currently set watermark parameters, and the process of adding a watermark to the target application window ends.
[0079] S207: Draw the target graphic canvas into the memory according to the watermark parameters.
[0080] S208: Determine whether the target graphics canvas is successfully drawn into the memory, if not, return to execute step S206, if yes, execute step S209.
[0081] After drawing the target graphics canvas to the memory, determine whether the target graphics canvas is successfully drawn to the memory. If not, it means that the process of drawing the target graphics canvas to the memory has failed, and the subsequent process of adding a watermark to the target application window cannot be performed according to the currently drawn graphics canvas. The process of adding a watermark to the target application window is ended. If so, it means that the subsequent process of adding a watermark to the target application window can be performed according to the currently drawn graphics canvas, and step S209 is executed.
[0082] The method of determining whether the target graphic canvas is successfully drawn to the memory may include determining whether the font size meets the preset requirements, determining whether the resolution exceeds the preset resolution range, determining whether the font color meets the preset color requirements, etc.
[0083] S209: Setting properties of the initial watermark window to obtain a set watermark window.
[0084] After determining that the target graphic canvas is successfully drawn to the memory, the initial watermark window is set to obtain a post-setting watermark window. By setting the initial watermark window, the post-setting watermark window can add a watermark without affecting the target application window's display of the original content, thereby improving the display effect.
[0085] In a specific implementation of the present application, setting the attributes of the initial watermark window may include the following steps:
[0086] Set the mouse and keyboard transparent transmission properties, border transparency properties and timed refresh properties for the initial watermark window.
[0087] When setting the properties of the initial watermark window, you can set the mouse and keyboard transparent transmission properties, border transparency properties, and timed refresh properties for the initial watermark window. By setting the mouse and keyboard transparent transmission properties for the initial watermark window, the blocking of mouse and keyboard input information is avoided. By setting the border transparency properties for the initial watermark window, the border of the watermark window is prevented from affecting the display effect of the target application window. By setting the timed refresh properties for the initial watermark window, the dynamic alignment between the watermark window and the target application window is ensured.
[0088] S210: Drawing the target graphic canvas from the memory to the set watermark window, so that the target application window displays the watermark information according to the target graphic canvas.
[0089] After the properties of the initial watermark window are set and the post-setting watermark window is obtained, the target graphic canvas is drawn from the memory to the post-setting watermark window, and the target application window displays the watermark information according to the target graphic canvas. By drawing the target graphic canvas from the memory to the post-setting watermark window with completed property setting, such as making the watermark window present the effects of transparent background, message transparent transmission, and watermark display, the display effect of the watermark information is improved.
[0090] S211: When the watermark information needs to be closed, the watermark software development kit is called to close the watermark interface so that the target application window closes the display of the watermark information.
[0091] When the watermark information needs to be turned off, the watermark software development kit is called to turn off the watermark interface, so that the target application window turns off the display of the watermark information. By setting the watermark software development kit to control the watermark interface on and off, the display and non-display control of the watermark information is realized, which improves the user experience.
[0092] See also Figure 3 , Figure 3 This is a structural block diagram of a watermark software development kit in the embodiment of the present application. The watermark SDK structure is divided into an interface layer, an embedding layer, a drawing layer, and a display layer, and each layer is called from top to bottom.
[0093] (1) Interface layer: provides an interface for external programs to call;
[0094] (2) Embedding layer: Obtain the handle of the target application window passed in from the interface, perform parent-child binding between the watermark window and the target application window in the embedding layer, and embed the watermark window on the target application window;
[0095] (3) Drawing layer: draw the graphics canvas into the watermark window according to the parameters passed in by the interface;
[0096] (4) Display layer: Draw the graphics canvas inside the watermark window, and the watermark window is embedded on the target application window.
[0097] See also Figure 4 , Figure 4 This is a flow chart of application window watermark generation and embedding display in an embodiment of the present application. The security application integrates the watermark software development kit, integrates the watermark parameters in the business code that needs to open the watermark, opens the watermark interface, and the watermark software development kit receives the watermark parameters, internally implements the window watermark generation and embedding technical process, and the target application window displays the plain text watermark information. If the watermark is to be turned off, the watermark software development kit is called to turn off the watermark interface, and the watermark software development kit internally turns off the overlay watermark, and the target application window no longer displays the watermark.
[0098] The present invention utilizes Windows graphics rendering technology, designs graphics rendering object interface and watermark display parameter setting interface, and packages them into watermark software development kit through unified compilation, which can support various application calls, support interface form customization of watermark content and format, including display content, font size, color, transparency, rotation, etc., and complete watermark display. The present invention internally instantiates the watermark window, and binds the target application window with the watermark window as a parent-child window, so as to embed the watermark window into the target application window.
[0099] Corresponding to the above method embodiment, the present application also provides an application window watermark adding device. The application window watermark adding device described below and the application window watermark adding method described above can refer to each other.
[0100] See also Figure 5 , Figure 5 This is a structural block diagram of a device for adding a watermark to an application window in an embodiment of the present application. The device may include:

[0104] The watermark information display module 54 is used to draw a target graphic canvas to the initial watermark window according to the watermark parameters, so that the target application window displays the watermark information according to the target graphic canvas.
[0105] It can be seen from the above technical solution that by obtaining the target handle corresponding to the target application window to be watermarked, the initial watermark window is embedded into the target application window according to the target handle, without the need for complex frameworks and a large amount of coding, thereby realizing the binding of the initial watermark window with the target application window, which greatly reduces the cost. The initial watermark window will only be embedded on the target application window and will not affect other windows. Compared with the full-screen watermark, it is more lightweight.
