Abstract

The present invention relates to a computer-implemented method, system and computer readable medium for determining illegitimate three dimensional videos. Methods are disclosed for efficient scene mapping process employed during the watermark extraction stage using non-blind watermarking methods, for example, singular value decomposition (SVD). Watermarks are embedded in a dual mode by treating the center video and depth video as separate channels of a three dimensional video. REF FIG: 1
