But it should definitely be possible to just replace your screen with a non standard filter that requires the right glasses filter to see so its even more obscure.
Now the real prize would be if theres a way to make it so sensitive or multi layered so that it's not feasible to brute force the encoding. I don't see much of a market for this tho. Anyone this worried about physical privacy should be worried about digital instead.
