Forensic marking, a type of watermarking, is an efficient means of detecting copyright violation and tracing unauthorized access to digital content. In this paper, a new video forensic marking algorithm is proposed which uses peak position modulation (PPM) and can embed sufficient information to trace an illegal distributor. PPMuses the positions of correlation peaks, which are modulated by user information. Furthermore, a forensic mark is embedded into a 2-level 3D discrete wavelet transform (DWT) domain. Experimental results show the robustness against various attack and the capacity improvement of proposed algorithm.
