Paper Abstract

Digital watermarking has been proposed for copyright protection in our digital society. We propose an adaptive digital watermarking scheme based on the human visual system model and a fuzzy logic technique. The fuzzy logic approach is employed to obtain the different strengths and lengths of a watermark by the local characteristics of the image in our proposed scheme. In our experiments, this scheme provides a more robust and imperceptible watermark.
