Abstract
Digital watermarking aims at embedding information in digital data. The watermark is usually required to be imperceptible, unremovable and to have a high information content. Unfortunately, these three requirements are contradicting. For example, having a more robust watermark makes it either more perceptible or/and less informative. This paper investigates the relationship between the watermark information content and the induced distortion due to quantisation, such as lossy compression.
