Paper Abstract

This paper describes a triple-layered watermarking scheme employing KLT and two layers of discrete cosine transforms, with data shuffled pseudo-randomly prior to the second DCT. In this way, the watermark is imperceptibly and robustly embedded into a set of multispectral images. The watermark is extractable without original host images. Simulation experiments are carried out to study the anti-attack performance. It is shown that the proposed technique is applicable to color and remote sensed multispectral images.
