PHOTOGRAPHIC COPY PREVENTION OF A SCREEN IMAGE

摘要

A method for preventing photographic capture of a displayed image on an electronically controlled screen using a photographic capture device is provided. The method includes intercepting an image for display; generating a plurality of subset frames based on the intercepted image; dividing the intercepted image into a plurality of subsections; generating a pseudo random number on each of the subsections within the plurality of subsections using a pseudo random number generator; mapping, on each of the subset frames within the plurality of subset frames, a group of subsections within the plurality of subsections that share a common generated pseudo random number; and determining a frame rate value for displaying the plurality of subset frames, which enables human visualization of the plurality of subset frames as a single perceived frame.

1. A method for preventing the photographic capture of a displayed image on an electronically controlled screen of a photographic capture device, the method comprising:
intercepting, using a processor device, an image for display on the electronically controlled screen; generating a plurality of subset frames based on the intercepted image; dividing the intercepted image into a plurality of subsections; generating a pseudo random number on each of the subsections within the plurality of subsections using a pseudo random number generator; mapping, on each of the subset frames within the plurality of subset frames, a group of subsections within the plurality of subsections that share a common generated pseudo random number, wherein a single mapped subset frame contains a single group of subsections within the plurality of subsections sharing the common generated pseudo random number and the mapping is performed from the lowest generated pseudo random number to the highest generated pseudo random number; and determining a frame rate value for displaying the plurality of subset frames, wherein the frame rate value enables a human visual recognition of the plurality of subset frames as a single perceived frame corresponding to the intercepted image and disables a visualization from the electronically controlled screen of the photographic capture device.
