“…The encoded watermark information is embedded in the quantized DCT/DST residuals of Iframes for different TUs sizes which they meet the conditions of free intra-frame error propagation which is proposed by Chang et. al., in [7]. The watermark data is extracted from the same set of I-frames on the decoding side.…”

“…In order to tackle the intra-frame error propagation problem, a free intra-frame error algorithm for HEVC has been proposed in [7]. The algorithm classifies the pixels to groups based on five cases along horizontal,vertical, and diagonal to protect a particular pixel set against intra-frame error effects.…”

When embed watermark into compressed video stream, distortion drift, including intraframe and inter-frame, is of the first important problem that must be taken into consideration. With the analysis of hierarchical b-picture (HBP) coding structure and drift-level mechanism, a new watermarking algorithm for 3D videos stream without distortion drift is proposed. Firstly the driftlevel of HBP coding structure is deeply investigated. Secondly, the spatiotemporal correlations of 3D videos are explored to increase the embedding capacity. Finally, the copyright information, which is preprocessed by secret sharing method, is embedded by matrix embedding method based on Error-correcting codes. Experimental results show that the proposed algorithm has higher embedding capacity and efficiency than the current algorithms.

Abstract-A large-capacity information hiding algorithm for HEVC is proposed. We modify the intra prediction modes in 4x4 luminance blocks to embed secret information. According to the probability distribution of the statistical optimal prediction mode and suboptimal prediction mode, we are establishing a mapping relationship between prediction modes and secret information. Modifying the intra prediction modes to embed secret information is based on the mapping. The extraction of information merely requires decoding the prediction mode from the bit stream. Experimental results show that the proposed hiding algorithm can embed information with large capacity and effectively guarantee the subjective and objective quality of video.
