Text-based session watermark
Text-based session watermarks help to deter and enable tracking data theft. This traceable information appears on the session desktop as a deterrent to those using photographs and screen captures to steal data. You can specify a watermark that is a layer of text, which displays over the entire session screen without changing the content of the original document.
Important:
Text-based session watermarking is not a security feature. The solution does not prevent data theft completely, but it provides some level of deterrent and traceability. We do not guarantee complete information traceability when using this feature. However, we recommend that you combine this feature with other security solutions as applicable.
The session watermark is text and is applied to the session that is delivered to the user. The session watermark carries information for tracking data theft. The most important data is the identity of the logon user of the current session in which the screen image was taken. To trace the data leakage more effectively, include other information such as server or client internet protocol address and a connect time.
To adjust the user experience, use the Session Watermark policy settings to configure the placement and watermark appearance on the screen.
Limitations
- Session watermarks are not supported in sessions where browser content redirection is used. To use the session watermark feature, ensure that browser content redirection is disabled.
- Session watermark is not supported and does not appear if the session is running in full-screen hardware accelerated H.264 or H.265 encoding mode with legacy NVIDIA drivers (in this case, NvCaptureType is set to 2 in the registry).
- Watermarks are not visible for session shadowing.
- If you press the Print Screen key to capture a screen, the screen captured at the VDA side does not include the watermarks. We recommend that you take measures to avoid screen captures being copied.
