We would like to prevent screen recording of a website due to security reasons. Our website contains some video materials which we don't want the visitors to copy using any screen recording software.

This means that when the website is viewed by a visitor he should not be able to record the website information using any screen recording software.

It is technically not possible!

Even if it WERE possible to stop simple capture programs, these can be easily bypassed by "lotech" solutions, like using an old video-cam to record the screen as it displayed and then redigitizing the taped recording!

If you put it on my screen, I can copy it and you can't prevent it because you have sent it to me.  It's out of your control when it is on my computer.

There is the "analog loophole". You cannot prevent people completely from copying your videos.

If the video content is secure, then play in locally on controlled computers, and confiscate all hardware before entering the room.

Other than that, you're on the "honor system".  How do you know that the person sitting in front of the computer is authorized?  Or that there isn't two people watching the screen?
