摘要：

In this paper, a new forensic watermarking algorithm which generates digital hologram from forensic mark and embeds it into DWT-SVD domain was suggested. Forensic watermarking is used to trace the illegal distribution. For the purpose of the high capacity, off-axis hologram is generated from forensic m and the hologram is embedded into subband of the DWT domain, so that we could reduce the signal interference. Also, we improved the algorithm safety and detection performance by using SVD for the signal embedded hologram. As a result, we were able to embed 128bits forensic mark for each step and totally 384bits can be embedded and trace the 3 distribution steps.
