What is Robust Invisible Watermarking of Volume Data Using The 3D DCT about?

This paper proposes a novel watermarking algorithm for 3D volume data based on the spread-spectrum communication technique. "Invisible" means that the 2D rendercd image of this watermarked volume is perceptually indistinguishable from that of the original volume. "Robust" implies that the watermark is resistant to most intentional or unintentional attacks.
