Nowadays, data hiding has become important for different reasons such as copyright violation and authentication. Conventional data hiding approaches may suffer from high capacity and high fidelity. In general, increasing capacity leads to distortion in carrier signal. In this paper, an efficient data hiding method, which has high capacity and high fidelity, is proposed for high-efficiency video coding. Hidden data are embedded into the coefficient of the discrete sine transforms at the transform domain level. The proposed method is basically based on matrix encoding approach that provides high capacity and high fidelity. In this paper, additionally, error propagation issue caused by data hiding is handled in the video encoding. Then, data hiding process is carried out without error propagation. Thus, distortion in visual quality is kept at minimum level during video encoding. Experimental results reveal that the proposed method exhibits outstanding performance in terms of visual quality and embedding capacity.

HEVC中基于矩阵编码的大容量高保真可逆数据隐藏

如今,由于侵犯版权和身份验证等不同原因,数据隐藏变得很重要。传统的数据隐藏方法可能会受到高容量和高保真度的影响。一般来说,增加容量会导致载波信号失真。本文提出了一种具有高容量和高保真度的高效数据隐藏方法,用于高效视频编码。隐藏数据在变换域级别嵌入到离散正弦变换的系数中。所提出的方法基本上基于提供高容量和高保真度的矩阵编码方法。在本文中,另外,在视频编码中处理了由数据隐藏引起的错误传播问题。然后,在没有错误传播的情况下进行数据隐藏过程。因此,在视频编码过程中,视觉质量的失真保持在最低水平。实验结果表明,所提出的方法在视觉质量和嵌入能力方面表现出优异的性能。
