The technology behind this fling is very exciting. It can overlay a "watermark" image that cannot be seen by the naked eye on the Horizon Virtual Desktop screen. More importantly, this "watermark" image is generated dynamically, can be customized by the Horizon administrator, for example, the watermark image can contain the desktop current user name, e-mail, date, machine name, IP address and so on. In addition, the watermark can not be obscured by any window, it will always float on all the windows.

When a user connects to a virtual desktop using a virtual desktop client, a blind watermark is included in each frame of the image that is sent from the remote virtual desktop to the client. Therefore, whether the customer is in the virtual machine screenshots, or the client software screenshots, this blind watermark information will be preserved.

Several employees of a company have been punished for leaking the intranet. So, how does a company know who leaked the company's secrets? is in the company intranet interface, the use of blind watermark technology.

for security reasons, many customers use virtual desktops to access their key confidential content, such as sales systems, office systems, and even financial systems. the Virtual Desktop blind watermark system brought by this fling will not enhance the productivity of the enterprise, but will add an invisible lock to the enterprise's anti-leak.

once someone has leaked the virtual desktop, and this is received by the administrator, than 2. Then the administrator can use the "echo" program included with this fling to develop the watermark. After the development of the watermark can be clearly seen picture, see picture 3, so as to know, who at what time, on which machine intercepted this picture.
