Of course Print Screen is not the only way to copy, so you also have to disable copy in the commonest two forms of the command.
To disable copy paste you also have to prevent the ability to select text using the cursor. This is the same as disable copy except that you now prevent the use of right click copy with the mouse, or Ctrl-C as a keyboard command. You have to prevent both of these methods to disable copy, and thus to disable copy paste. Alternatively, you can allow selection of text but not save the selection to memory so that there is nothing available to paste.
You will notice that we do not have to disable paste, because, if there is nothing to copy then we have paste disabled automatically, and that is much easier than having to develop a system to disable paste explicitly.
Another common way to copy information is to use a screen grabber application. It is more complicated to disable copy where a screen grabber is involved. It will usually have its own method for making a copy of the screen. So to disable copy it is necessary to do several things: present a false image to the screen grabber; delete the copy it is making; prevent the screen grabber from being able to run. Any method to disable copying will have to use all three methods, or possibly more.
There are many ways to disable copy and to disable paste. If you have copy disabled then you have paste disabled. If you do not disable copy then you risk having your documents copied and distributed.
Technologies used to disable copy & paste
To disable copy and paste you either need to hook into the Operating System commands or the application. This can be done via plugins but they can be circumvented and often don’t work when the application is updated. That is why to be effective at preventing copy and paste, a dedicted application to view protected content should be used.
