Has anyone ever considered developing a screenshot resistant tech?

Seems very achievable for text.

Most screens are 60Hz.

What if I broke a message into layers, eg 6 bands and each band is displayed 1 frame out of phase?

Band 1: would display characters 1, 7, 13, 19

Band 2: would display characters 2, 8, 14, 20

Band 3: would display characters 3, 9, 15, 21

The screen would draw band 1 as frame 1, band 2 as frame 2, band 3 as frame 3, etc. frame 7 would cycle back to band 1.

So each character is only actually draw for 1/6th of the time, but I suspect in dark mode this is still eligible. It still gives 10 frames per second for each character.

Crucial… any screenshot can only capture 1/6th of the text.

Has anyone ever tried to implement something like this? Could obviously be defeated still, but cannot just screen grab and forward.
