Abstract
The marking of a video stream to impart a unique identifier commences by first identifying portions within the video stream readily susceptible to change in a visually imperceptible manner. Thereafter, a combination of visually imperceptible changes is applied to the identified portions at random intervals for randomly varying intervals to mark the video stream. Each change in the stream correlates a particular bit sequence so that a combination of different changes yields a string of bit sequences that can particularly identify the stream.
