Abstract
Systems and methods are provided through which marks are generated for combination with a host image, in which source or user information is encoded into the mark either as a visually perceptibly unobtrusive pattern, or encoded by an arrangement of visually perceptible marks. Systems and methods are also provided for decoding or estimating the user information from images that contain the marks and determining the user or source that the mark indicates within a measure of certainty.
