Abstract This paper presents a robust steganography method for HEVC based on secret sharing. To prevent intra-frame distortion drift, three Classes of intra-frame prediction are defined. To improve the robustness of the secret message, the embedded message has been encoded into n sub-secrets by using (t, n)-threshold secret sharing. Then the encoded message is embedded into the multi-coefficients of the selected 4 × 4 luminance DST blocks which meet the Classes mentioned above. When the test video faced with different loss-rates, the survival rate of the proposed steganography method has increased by around 24.27%, 27.38%, 61.91% and 32.26% compared with Swati, Hayat, and Shahid (2014), respectively; the survival rate of the proposed steganography method has increased by around 28.74%, 34.60%, 56.05% and 41.40% compared with Liu, Liu, and Zhao (2017), respectively; when the loss-rate is less than 15%, the proposed steganography method can get 100% survival rate. And the experiments prove that the proposed method can achieve high performance than previously video steganography methods based on HEVC, especially for visual quality and robustness performance.

一种基于秘密共享的HEVC鲁棒隐写方法

摘要 本文提出了一种基于秘密共享的健壮的HEVC隐写方法。为了防止帧内失真漂移，定义了三类帧内预测。为了提高秘密消息的鲁棒性，嵌入的消息通过使用 (t, n) 阈值秘密共享被编码为 n 个子秘密。然后将编码的消息嵌入到满足上述类别的所选 4 × 4 亮度 DST 块的多系数中。当测试视频面临不同的损失率时，所提出的隐写术方法的存活率与 Swati、Hayat 和 Shahid（2014）相比分别提高了 24.27%、27.38%、61.91% 和 32.26%；与刘、刘、和赵（2017），分别；当损失率小于 15% 时，所提出的隐写术方法可以获得 100% 的存活率。并且实验证明，所提出的方法可以实现比以前基于HEVC的视频隐写方法更高的性能，尤其是在视觉质量和鲁棒性方面。
