High capacity robust forensic marking using computer generated hologram

In this paper, a new forensic marking algorithm which traces illegal distributors at each distribution step and embeds holographic forensic mark into multiple DCT-SVD domain is proposed. This algorithm can embed high capacity information using the off-axis hologram and ensure the robustness using DCT-SVD domain. This also can achieve enough payloads for multiple steps of distribution and robustly survive various attacks such as rotation, additive noise, and compression.
