How do I protect screen data from being captured by the camera?

Question

Android

Good afternoon, I’m very interested in the question of how to protect the data on the screen of an android device from being taken by a camera, more precisely, how to trick the camera so that it sees krakozyabry for example? Actually, if there are interesting articles on this subject, I would gladly read it, thanks for your attention.

Answer 1

No way. The maximum you can set is a watermark or hidden marks .
Whatever the user sees, the camera will also see. Well, you can force the user to stick a polarizing film and put on special glasses and do not forget to fasten him to the battery in the basement

Option, no?)

Answer 3

No way. Or almost nothing.
The camera is a mechanical similarity of the eye, everything that the user sees, the camera will also see. You can create a separate workplace with a monitor sealed with a polarizing film, of course, but surely it was about selling a certain program and preventing data from being captured by another phone?

Answer 4

Look for a smartphone with a screen that has a narrow field of view
You can "trick" the camera if you patch it

Answer 5

You can try to experiment with the frame rate, camera shots of older displays often show only half of the screen or some part .... you can also display data in a very similar color that distinguishes the eye, but in the picture it will be flooded with one color. In painting, this often happens, when photographing a picture - the colors are different by eye, but in the photo everything is merged
