you can never counter someone taking a picture of the screen.
Except with digital watermarks. Photocopiers generally recognize things like currency and refuse to copy at high fidelity. The PS3 I believe would refuse to play ripped cinema soundtracks all the way through, using audio watermarking. It's conceivable that cameras could be required to do the same thing for digital restriction watermarks.

I guess they could try to do a denial of service attack on the typist by deliberately overusing letters from the same vertical keyboard row to wear out the finger.
