[0002] A watermark is a mark or information added to the screen of an electronic device, usually displayed on the screen in a transparent or semi-transparent form. The main function of a watermark is to protect intellectual property rights, prevent counterfeiting, and enhance security.
[0003] Currently, there are many ways to prevent leakage by adding watermarks, such as adding a watermark to the entire screen, or adding a watermark to the entire process, and then finding the leaker through the watermark content to achieve the purpose of preventing leakage.
[0004] However, the current watermarking method will cause the screen to be filled with watermarks when it is not necessary. For example, when the process window with the watermark is not in the display state, the process window in the display state does not need to be watermarked. At this time, it is unnecessary to add a full-screen watermark. The full-screen watermark may affect the user experience, and the watermark may also block some data, thereby reducing the user's work efficiency. Summary of the invention

[0038] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0039] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.
[0040] In addition, the terms "first" and "second" etc. are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
[0041] Please refer to Figure 1 , Figure 1 1 is a flow chart of a watermark-based anti-leakage method provided in an embodiment of the present application, comprising the following steps S101 to S103:
[0042] S101, monitoring the screenshot operation;
[0043] There are multiple terminals used by employees and a server for managing the terminals in the company's intranet. Employees will open various processes on the terminals, some of which need to be kept confidential and some do not. The watermark-based anti-leakage method provided in this application is applied to the terminal.
[0044] In this step, the terminal monitors the screenshot / screen recording actions of all processes, observes some processes with screenshot actions, and determines how the screenshots are taken.
[0045] S102, when it is monitored that a process is performing a screenshot operation, determining whether the window of the target process is in a visible state, and obtaining a determination result that the target process belongs to a process in a preset process library;
[0046] In the present application, a preset process library is pre-constructed. The processes in the preset process library are processes that need to be kept confidential. Each process in the library can correspond to a process identifier.
[0047] When an employee opens a process in the terminal, the terminal will determine whether the opened process is a process in the preset process library. If so, the opened process is the target process. When a process is taking a screenshot, it is necessary to determine whether the window of the target process is in a visible state.
[0048] The judgment result may be that the window of the target process is in a visible state, or may be that the window of the target process is not in a visible state.
[0049] S103: Determine whether to display the target watermark according to the judgment result.
[0050] Specifically, the above step S103 includes: according to the judgment result that the window of the target process is in a visible state, displaying the target watermark and monitoring whether the screenshot operation is completed; when monitoring that the screenshot operation is completed, deleting or hiding the target watermark.
[0051] When a process takes a screenshot, if the window of the target process is visible, the target watermark is displayed. The target watermark can be a watermark window drawn in advance according to the required watermark style. After the watermark window is drawn in advance, it is hidden first and displayed when a process takes a screenshot and the window of the target process is visible. The target watermark can also be created and displayed when a process takes a screenshot and the window of the target process is visible. After the screenshot operation is completed, the watermark window is deleted or hidden, thereby minimizing the impact of the watermark on work efficiency and improving the user experience.
[0052] Specifically, the above step S103 further includes: according to the judgment result that the window of the target process is not in a visible state, the target watermark is not displayed.
[0053] Specifically, although the target process is opened, if its window is in a hidden state, or if there is no other process for screenshot operation, it is not necessary to display the watermark on the terminal screen, while the prior art will display the watermark after the target process is opened, which will affect the user experience and work efficiency. In the present application, when other processes perform screenshot operations, although the target process is opened, the target watermark is not displayed when its window is in a hidden state, thereby reducing the impact of the watermark on the user experience and work efficiency.
[0054] For example, when the desired watermark style and the controlled process A.exe are set, if a process B.exe with a screenshot function is ready to take a screenshot, all visible windows on the desktop need to be checked to see if there is a window of the controlled process A.exe. If so, the watermark will be displayed when taking the screenshot; otherwise, the watermark will not be displayed.
[0055] The above method of the present application may also include the following steps:
[0056] Receiving update data for the preset process library;
[0057] Updating the preset process library according to the update data;
[0058] The update data includes processes that need to be added or deleted.
[0059] It can be seen that the present application can dynamically update the preset process library. New processes that need to be controlled are added to the preset process library, and processes that do not need to be controlled can be removed from the preset process library, so as to timely avoid the leakage of controlled processes in the form of screenshots, and can also promptly release processes that do not need to be controlled to improve user experience.
[0060] For ease of understanding, this application also provides Figure 2 A flowchart of a specific watermark-based anti-leakage method is shown.
[0061] like Figure 2 As shown, the terminal starts running and observes whether there is a process executing a screenshot action. If so, pay attention to whether the window of the target process is in a visible state. If it is in a visible state, create and display a watermark, and observe whether the screenshot action is completed. If the screenshot action is completed, delete the watermark. If the screenshot action is not completed, continue to display the watermark.
[0062] The watermark-based anti-leakage method provided in the embodiment of the present application has the following beneficial effects:
[0063] In this application, the screenshot operation is monitored; when a process is monitored to perform a screenshot operation, it is determined whether the window of the target process is in a visible state, and a judgment result is obtained, and the target process belongs to a process in a preset process library; according to the judgment result, it is determined whether to display the target watermark. Compared with the prior art, when the process triggers the screenshot operation, the present application can determine whether the window of a specified process is in a visible state, and if so, a watermark is displayed to avoid information leakage, and if the window of no specified process is in a visible state, no watermark is displayed. It can be seen that the present application can avoid unnecessary watermark addition, thereby avoiding reduced work efficiency.
