Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to prevent others from taking screenshots or photos of the desktop screen, which may lead to company copyright disputes or leak sensitive company information, cloud gaming systems are required to have a watermark function for remote desktop systems. However, current cloud desktop watermarking technologies all add watermarks to the remote desktop of the virtual machine, and current cloud desktop watermarking technologies are generally clear watermarking technologies, and there is a lack of research on dark watermarking technologies for independent hosts in cloud gaming systems.

[0040] To this end, the embodiment of the present application proposes a dark watermark adding solution for a cloud gaming system, which can prevent information leakage and provide copyright protection.

[0041] The present application embodiment discloses a method for adding a dark watermark to a cloud gaming system. Figure 1 and Figure 2 As shown, the method includes:

[0042] Step S11: Obtain the watermark information sent by the user.

[0043] In this embodiment, the user sends watermark information through the web (network) according to his own needs. The watermark information includes watermark type, watermark color, font, watermark position, etc. The watermark type includes dark watermark, watermark color includes all colors supported by the system such as red, green, blue, etc., fonts include all fonts supported by the system such as Songti and Kaiti, and the watermark position is mainly any coordinate of the display screen such as center and upper left.

[0044] Step S12: Determine the desktop state of the current desktop of the cloud host, wherein the desktop state includes a full-screen state and a non-full-screen state, the full-screen state includes a full-screen cloud game state and a full-screen non-cloud game state, and the non-full-screen state includes a non-full-screen cloud game state and a non-full-screen non-cloud game state.

[0045] In this embodiment, the desktop state of the current desktop of the cloud host is determined. It can be understood that the desktop state includes a full-screen state and a non-full-screen state. The full-screen state includes a full-screen cloud game state and a full-screen non-cloud game state. The non-full-screen state includes a non-full-screen cloud game state and a non-full-screen non-cloud game state.

[0046] Step S13: determining a target adding method from a plurality of preset dark watermark adding methods according to the desktop status of the cloud host, and using the target adding method to add the watermark information to the cloud host.

[0047] In this embodiment, the watermark adding method is determined according to the desktop status of the current desktop, and the watermark information is added according to the corresponding adding method, which not only enhances the brand image of the enterprise, but also prevents information leakage, provides copyright protection, and fills the research gap of the existing technology on the dark watermark technology of the cloud gaming system.

[0048] In a specific implementation, if the desktop state is a non-full screen state, a target adding method is determined from a plurality of preset dark watermark adding methods according to the desktop state of the cloud host, including: determining the target adding method of adding the watermark information based on a created transparent layer from the plurality of preset dark watermark adding methods according to the desktop state of the cloud host.

[0049] That is to say, when the desktop is a normal desktop and there is no full-screen window, watermark information can be added by adding a transparent layer. Specifically, a target transparent layer is created, and the transparency value of the watermark information is set to the target value, and then the watermark information is added to the target transparent layer to obtain a dark watermark layer. Further, the layer blending mode of the dark watermark layer and other layers of the current desktop is set to the penetration mode, and the dark watermark layer is placed on the top layer of each layer, wherein the target value can be 1. The following is the code implementation process of adding watermarks in non-full-screen state:

[0050] set window transparency

[0051] SetLayeredWindowAttributes(hWnd, BACKGROUND_COLOR, m_mark_transparent_, flag_);

[0052] / / Remove borders and title blocks

[0053] SetWindowLongW(hWnd, GWL_STYLE, GetWindowLongW(hWnd, GWL_STYLE) & ~WS_CAPTION);

[0054] / / Set the key-rat event penetration

[0055] SetWindowLongW(hWnd, GWL_EXSTYLE, (GetWindowLongW(hWnd, GWL_EXSTYLE))| WS_EX_LAYERED | WS_EX_TRANSPARENT);

[0056] / / TOPMOST

[0057] SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);

[0058] Furthermore, when the client parses the watermark, it first layers the current desktop image according to the transparency value to obtain a dark watermark layer with a transparency value of 1, and marks the watermark information in the dark watermark layer as a target color, such as red, blue and other obvious colors, to achieve watermark parsing.

[0059] In another specific implementation, if the desktop state is a full-screen state, a target adding method is determined from a plurality of preset dark watermark adding methods according to the desktop state of the cloud host, including: determining the target adding method of adding the watermark information based on the created temporary rendering surface from the plurality of preset dark watermark adding methods according to the desktop state of the cloud host.

[0060] That is to say, when there is a full-screen window on the desktop, watermark information cannot be added by adding a transparent layer, but the target adding method of adding the watermark information based on the created temporary rendering surface. Specifically, first create a target temporary rendering surface, wherein the length and width of the target temporary rendering surface are consistent with the length and width of the current desktop of the cloud host, and create a target texture, load the watermark information into the target texture, and then use the D3D11 device context to perform rendering operations. Specifically, use a shader and a vertex buffer to render the target texture to the target temporary rendering surface, and finally copy the target temporary rendering surface to the current desktop.

[0061] Furthermore, before copying the target temporary rendering surface to the current desktop, it also includes: determining the current desktop as a rendering target, and using the shader and the vertex buffer to render the game data to the current desktop. In this way, the current desktop in the present application can contain both the game image and the watermark image. In summary, the core of the above process is to render the game image and the watermark image by using a temporary rendering target surface and texture, and then copy the content of the temporary rendering target surface to the current desktop so as to contain both the game image and the watermark image.

[0062] It can be seen that the present application discloses a method for adding a dark watermark to a cloud gaming system, including: obtaining watermark information sent by a user; determining the desktop state of the current desktop of the cloud host, wherein the desktop state includes a full-screen state and a non-full-screen state, the full-screen state includes a full-screen cloud gaming state and a full-screen non-cloud gaming state, and the non-full-screen state includes a non-full-screen cloud gaming state and a non-full-screen non-cloud gaming state; determining a target adding method from a plurality of preset dark watermark adding methods according to the desktop state of the cloud host, and using the target adding method to add the watermark information to the cloud host. In summary, the present application proposes a method for adding a dark watermark to a cloud host where a cloud gaming system is located. The core of the application is to determine a method for adding a watermark according to the desktop status of the current desktop, and to add watermark information according to the corresponding method. Specifically, the desktop status includes a full-screen status and a non-full-screen status. The full-screen status includes a full-screen cloud gaming status and a full-screen non-cloud gaming status. The non-full-screen status includes a non-full-screen cloud gaming status and a non-full-screen non-cloud gaming status. In this way, not only the brand image of the enterprise is enhanced, but also information leakage can be prevented, copyright protection can be provided, and the research gap in the existing technology for dark watermark technology for cloud gaming systems can be filled.
