Overview: This white paper presents a new watermark design tool for digital images and digital videos that are based on human visual system (HVS) characteristics. This tool has basic mechanisms of inhibitory and excitatory behaviors of HVS cells that are used to determine image dependent upper bound values on watermark insertion which allows inserting maximal allowable transparent watermark, which in turn is extremely hard to attack with common image processing. The paper shows that the entropy-masking model provides watermark scheme with increased transparency and henceforth increased robustness.
