Background technique

As the earliest project in the cloud computing industry, virtual desktops have huge market scale. In recent years, virtual desktops have developed vigorously in China, including banks, armed police forces, and government agencies, which have successively adopted virtual desktop technology to replace traditional PCs. Virtual desktop is a revolution of enterprise IT architecture, which brings mobile computing experience and meets the needs of many specific industries.

Among customers such as governments, banks, and troops, information security is a top priority. In terms of information security, it is generally possible to restrict users' file transfers, copy peripherals, and control Internet permissions through technical means, but they cannot control users' behaviors such as taking pictures and recording screens.

Digital watermarks play an important role in information security and copyright protection. The files generated by users taking pictures and recording screens will also have watermark content. Specific watermark content (such as corporate information, user ID information, etc.) provides traceability. in accordance with.

In the normal mode, there are generally two modes for adding watermarks in the computer operating system. One is to implement the watermark function by a third-party application, such as adding watermarks in applications such as office and pdf. This method of adding watermarks is only for applications As such, it cannot be extended to other applications, and the watermark function is tightly coupled with the application and is not universal. The second watermarking mode is to add applications to the operating system. Essentially, this method is to add applications to the operational system, where the application draws on the top layer and superimposes the digital watermark to the spatial domain of the image. However, in this way, the application belongs to a process in the operating system, the administrator cannot restrict the user's start and stop behavior, and there are problems such as preemption with other applications.

It can be seen that when adding a watermark in the prior art, the watermark can only be added for a specific application, and the administrator cannot prevent the user from stopping the behavior of adding the watermark by himself.

When the virtual desktop client 110 initiates the process of logging in to the virtual desktop 140, the user first authenticates the user information to the virtual desktop management center 120 and obtains the watermark configuration information corresponding to the user. When the virtual desktop client 110 is connected to the virtualization server 130, it carries the above watermark configuration information. The virtual desktop management center 120 manages and controls the entire virtualization platform, such as desktop information, user information, and corresponding relationships, and saves the user's watermark configuration information for the virtual desktop client 110 to query and use. The virtualization server 130 is a supporting platform on which the virtual desktop 140 runs, and runs a virtual desktop device simulation process. The virtual desktop device simulation process saves the watermark configuration information of the user corresponding to the virtual desktop 140. When the display content of the virtual desktop changes, the virtual desktop device simulation process adds a watermark to the virtual desktop according to the watermark configuration information, and forwards the display content to the terminal display corresponding to the virtual desktop client. The virtual desktop 140 is an object operated by a virtual desktop user. When the display content in the virtual desktop 140 changes, it is transmitted to the virtual desktop device simulation process through the graphics card driver, and the virtual desktop device simulation process adds a watermark and continues to send to the client for display.
