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)

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.

I would reccomend you take a look at https://datapatrol.com where they provide an enterprise solution for Desktop Screen Watermark. Their watermarks are dynamic and adaptive containing the meta-data of system information (logged-in user, IP Address, Time, Machine, ...etc). The solution isn't free but it's totally professional one with many other features as well.

I've seen it being adapted by many organizations looking to stop insiders from taking photos with their cellphones.

Note: the screen watermark can be configured so it's not annoying to end-users, and it supports multisession which could be used on servers with more than one user logged, each will see his own watermark policy on top.

You may want to try Screen Watermark (https://www.xSecuritas.com). They also have an enterprise edition allowing you to add watermarks to video conferences, printed documents, prevent screen capture, use invisible watermarks, and set various policies.
