Abstract: Abstract: The widely application of 3D video can provide good carrier for information hiding. Here, an information hiding algorithm based on the background High Efficiency Video Coding (HEVC) was proposed. The multi-view background images are used as the carriers. First, these images will be decomposed into three gray-scale components using lαβ color space theory. Second, the components α and β of these images will be transformed by DCT method. Last, the secret information will be embedded into the embedding regions repeatedly. With relative low energy weight, the mid-frequency part of α and β after DCT transform are both chosen as the embedding regions, which are embedded with the secret information. The experiments show that the imperceptibility and robustness can be improved by 13.7% and 35.6% respectively.
