Google the fingerprinting and traitor tracing techniques used by media studios. If a user screen records their HBO stream, or uses a cam in a theater, the studio can identify exactly which user it was streaming to or exactly which time and theater showing it was recorded in. This fingerprint is resistant to image warping/flipping, bitrate downsampling, image desaturation, cropping, frame drops, added noise, and nearly everything else.
