摘要:

为了进一步提高HEVC信息隐藏过程中的嵌入效率,提出了一种HEVC帧内预测模式调制的信息隐藏方法。该方法根据密钥生成每个CTU的空间点阵维数N(N=2,3,4),利用帧内预测模式选取规则选出N个顶角处的帧内预测模式,通过空间点阵映射算法计算出映射值 F;然后从秘密信息比特文件中读取 N 个比特,转换成十进制数D。实现了在N个帧内预测模式中最多改变一个模式即可嵌入N个比特秘密信息。实验验证该方法具有高嵌入效率、小码率增加以及视频质量几乎没有下降的特性,通过抗隐写实验证实所提方法有高隐蔽性。

Abstract:

For further improving the embedding efficiency in the processing of HEVC information hiding,a method for HEVC information hiding based on intra prediction models modulation was proposed.The space lattice dimen-sion N(N = 2,3,4)of each CTU was generated according to the key.The selection rule of intra prediction mode was utilized to select N modes which were located at vertex angle.The N modes were mapped to the value F through the space lattice mapping algorithm.Then N bits secret information were read from the bit file and converted to a deci-mal number D.In this way,N secret information bits were embedded in N intra prediction modes by modifying at most one mode.The experimental results approve that the proposed method has high embedding efficiency,small rate increase and minimal influence on the video quality and the anti-steganalysis experiment confirms that the pro-posed method has high concealment.

Key words: HEVC, information hiding, intra prediction modes, space lattice
