[0040] With reference to the drawings, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0041] In the specification and claims of the present application and the above drawings, the terms "first", "second" are used only for the purpose of description, and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0042] Figure 1 is a flow chart of the identification method of the screenshot window according to an embodiment of the present application. As shown in Figure 1 The identification method of the screenshot window according to the embodiment of the present application includes the following steps:

[0043] S101: obtaining the title and class name of the screenshot window;

[0044] S102: obtaining the application program file name corresponding to the screenshot window; and

[0045] S103: identifying the screenshot window according to the title, class name and corresponding application program file name of the screenshot window.

[0046] The title and class name of the window can be obtained by combining the hwnd obtained in the handle_win_event function with the Windows API functions GetWindowText and GetClassName. Further, the process ID corresponding to the hwnd can be obtained by GetWindowThreadProcessId. Then, according to the process ID, the absolute path of the corresponding program can be obtained by using the method of OpenProcess, and the EXE file name of the program can be extracted from the path. By combining the window title, window class name and EXE file name, the window of the screenshot software can be accurately filtered out.

[0047] Specifically, in the screenshot window identification method provided in the embodiments of the present application, the title and class name of the current active window are obtained by using functions GetWindowText and GetClassName of an operating system API (such as Windows API) for example. The window title can reflect the function or content of the window, and the class name identifies the window type or the application to which the window belongs, both of which provide the basis for preliminary identification. The executable file (.exe) path or name associated with the window is further obtained by using a system function such as OpenProcess. The application program file name directly corresponds to a specific software, and provides underlying verification for window identification. Finally, the window title, class name and application program file name are comprehensively compared, and a preset rule base or machine learning model is combined to determine whether the window is a screenshot window. For example, if the window title contains keywords such as "screenshot", the class name belongs to a known screenshot tool, and the application program file name is a screenshot software executable file, it is determined to be a screenshot window.

[0048] The screenshot window identification method provided in the embodiments of the present application is suitable for scenarios that require accurate identification of user screenshot operations, such as executing subsequent operations in automated testing, preventing sensitive information leakage in security monitoring, and providing customized services according to user screenshot behavior. The screenshot window identification method provided in the embodiments of the present application provides technical support for related applications through efficient and accurate screenshot window identification, which helps to improve user experience and system security.

[0049] In summary, in the screenshot window identification method provided in the embodiments of the present application, the title and class name of the screenshot window are first obtained, then the application program file name corresponding to the screenshot window is obtained, and finally the screenshot window is identified according to the title, class name and application program file name of the screenshot window. The screenshot window identification method provided in the embodiments of the present application provides technical support for related applications through efficient and accurate screenshot window identification, which helps to improve user experience and system security.

[0050] Further, in some embodiments of the present application, the title and class name of the screenshot window are obtained, including:

[0051] obtaining a canvas window handle of the screenshot window; and

[0052] Based on the canvas window handle of the screenshot window, the title and class name of the screenshot window are obtained. Specifically, by traversing system windows through, for example, an operating system API (such as a Windows API), a function such as FindWindow or EnumWindows is used in combination with a window title keyword (such as "screenshot") or a known class name to filter the target window. The canvas window handle, as a unique identifier of the window, is the basis for subsequent acquisition of window properties. Then, the GetWindowText function is called, and the handle parameter is passed in to read the window title text, reflecting the window function or status (such as "screenshot in progress"). The GetClassName function is called, and the handle parameter is passed in to obtain the window class name, identifying the window type or the application it belongs to (such as SnippingTool corresponding to the Windows screenshot tool). Through the above process, the title and class name of the screenshot window can be accurately obtained, providing a reliable basis for subsequent window recognition, operation, and automated testing. This method combines system APIs and filtering logic to achieve efficient and accurate window information acquisition, with practicality and scalability.

[0053] Further, in some embodiments of the present application, the obtaining of the application program file name corresponding to the screenshot window comprises:

[0054] Based on the canvas window handle of the screenshot window, the process identifier corresponding to the canvas window handle is obtained.

[0055] Based on the process identifier corresponding to the canvas window handle, the absolute path of the corresponding program is obtained; and

[0056] The application program file name corresponding to the screenshot window is extracted from the absolute path of the corresponding program.

[0057] Specifically, the process identifier associated with the window is obtained by using, for example, an operating system API (such as GetWindowThreadProcessId in Windows API) and passing in the canvas window handle of the screenshot window. The process identifier is a unique numerical identifier of the process, which is used for subsequent operations. Based on the process identifier, relevant APIs (such as OpenProcess in combination with QueryFullProcessImageName or GetModuleFileNameEx) are called to open the process and obtain the absolute path of its executable file. This path details the location of the program in the file system and is an important basis for identifying the application program. Then, the obtained program absolute path is parsed to extract the file name part. The file name usually corresponds to the application program name, directly reflecting the software to which the window belongs.

[0058] Through the above process, the application program file name corresponding to the screenshot window can be efficiently and accurately obtained, providing reliable support for window recognition, security monitoring and other scenarios. The method combines system API and path analysis technology, and has practicality and scalability.

[0059] Further, in some embodiments of the present application, before the title and class name of the screenshot window are obtained, further comprising:

[0060] Identifying the creation and / or destruction of all screenshot windows.

[0061] Specifically, in some embodiments of the present application, to ensure the accuracy and efficiency of the screenshot window identification process, before obtaining the title and class name of the screenshot window, a preliminary operation is performed, that is, the creation and / or destruction of all screenshot windows is identified. For example, the window management API provided by the operating system (such as the SetWinEventHook function in Windows API to listen to window events) or the polling mechanism to periodically check the changes of the window list is used to monitor the creation and destruction of the screenshot window in real time.

[0062] This step helps to dynamically grasp the state change of the screenshot window, ensures that the relevant information of the window is obtained in time after the window is created, or the necessary data processing is completed before the window is destroyed, so as to avoid information omission or incorrect identification.

[0063] Further, in some embodiments of the present application, after the creation and / or destruction of all screenshot windows is identified, further comprising:

[0064] Determining whether the screenshot window is legal;

[0065] If yes, the screenshot window is allowed to be created; and

[0066] If no, the canvas of the screenshot window is displayed as a black screen.

[0067] Specifically, in embodiments of the present application, to ensure system security and user experience, after the identification of the creation and / or destruction of the screenshot window is completed, the legality of the window is further judged, and corresponding processing measures are taken, that is, the legality of the screenshot window is evaluated in combination with preset rules (such as window class name, title keyword, application source, etc.). The legality of the window is determined by obtaining the window information through the system API and comparing and analyzing the rules.

[0068] If the window is legal, it is allowed to be normally created and displayed, and the user can continue to perform the screenshot operation, so as to ensure the normal use of the function. If the window is illegal (such as a disguised window created by malicious software), the canvas of the window is displayed as a black screen, preventing the user from performing the screenshot or other operations, and effectively protecting the system security.

[0069] Through the above legality judgment and targeted processing, the precise control of the screenshot window is realized, ensuring the dual improvement of system security and user experience, and having practicality and scalability.

[0070] Further, in some embodiments of the present application, after obtaining the title and class name of the screenshot window based on the canvas window handle of the screenshot window, the method further comprises:

[0071] intercepting the screenshot window meeting the condition.

[0072] Specifically, after obtaining the title and class name of the screenshot window, the window meeting the condition is further intercepted to realize precise control. According to preset rules (such as the window title containing sensitive keywords, the class name belonging to risky applications) or dynamic strategies, the interception condition is set. Through system API or process monitoring technology, the window state is monitored in real time. When the window meeting the condition is detected, the interception logic is triggered. Through this process, active control of the screenshot window can be realized, providing protection for system security and compliance use.

[0073] Further, in some embodiments of the present application, after intercepting the screenshot window meeting the condition, the method further comprises:

[0074] adding a watermark on the canvas corresponding to the screenshot window meeting the condition.

[0075] Specifically, after completing the interception operation of the screenshot window meeting the condition, a watermark is further added on the corresponding canvas. For the intercepted screenshot window, a preset watermark (such as text, pattern or semi-transparent identifier) is superimposed on the canvas area. The watermark content can include user information, timestamp, security warning, etc. to identify the window state or record operation traces. This process builds a complete control chain from risk identification to content protection through the linkage of interception and watermark addition, which is suitable for enterprise security control, copyright protection and other scenarios.

As shown in Figure 2 The screenshot window identification device 200 of the embodiments of the present application comprises a title acquisition module 210, a file name acquisition module 220 and a window identification module 230, wherein:
