I am working in a government position where we regularly process confidential information. We are looking into a possible way to patch the analog-hole problem and discourage users from taking photos of their computer screen.

I was wondering if we could put a whitewashed watermark (that contains system data like the IP address, computer name, user name, etc.) on the display at all times. We are using only MS Windows hosts BTW.

We are aware that this would be somewhat counter-productive and that many users can skillfully remove the watermark using photo editing programs, but we don't have to simply "trust" every user (we have too many of them)

    Do you mean you want a desktop background, or you want this to show ontop of all open applications with transparency? Something like thewindowsclub.com/overlay-image-windows-desktop-wallpaper Also see superuser.com/questions/218270/… – Dave Apr 4 '16 at 7:45
  • sounds like the latter, but he wants something constantly over everything else/always on top – Journeyman Geek Apr 4 '16 at 7:48
  • windows does something similar when it detects a licensing problem so it's definitely possible but i don't if you can trigger something like that on your own – conquistador Apr 4 '16 at 7:50
  • You are looking for BGInfo This does exactly what you are looking for and is customizable. We use it on some of the workstations here in the training rooms and User Level computers. – NetworkKingPin Apr 4 '16 at 7:59
  • @NetworkKingPin as far as i know BGInfo only modifies desktop background so watermark won't be visible on top of another program. – conquistador Apr 4 '16 at 8:05

You could try Rainmeter. Customize an existing skin (there are plenty of skins on internet) that includes all the information that you want to show on desktop. Like this:

enter image description here

And you can set it as Position: Stay topmost. It means that it will be always on top even over user windows.

You need to make sure that the user can't kill the rainmeter process.

  • This is true dont know why I didnt think about this I use rainmeter on all my computers in my home lab. +1 – NetworkKingPin Apr 4 '16 at 8:30
