Signal rich art is an alternative paradigm for watermarking, in which we embed a signal in an image or software application such as a website or app as a visible artistic pattern. In this paper we present a new algorithm for generating signal carrying patterns from a dictionary of objects which we call object placement. In an alternative approach, called object position modulation, we locally perturb the positions of objects in a given pattern to embed the signal. We also present advances in previous techniques.
Signal rich art is an application of watermarking technology to communicate information using visible artistic patterns. In this paper we show new methods of generating signal carrying patterns, simplifications of earlier methods, how to embed a vector watermark signal in applications and how to use signal symmetries to expand the detection envelope of a watermark reader.
