摘要
针对在较大数据量传递的场景中使用可逆信息隐藏(RDH)保护数据时嵌入效率和抗检测能力较低的问题,提出一种基于二维模运算的高效率可逆信息隐藏方案。首先通过模运算较小的修改像素值嵌入较大的信息量,再结合增强的进制转换系统增加嵌入位数,最后使用折半法结合双图像赋予可逆性。在USC-SIPI标准图像库上进行的仿真实验结果表明,在嵌入高达100万比特秘密信息时,所提方案的隐写图像的峰值信噪比(PSNR)值保持在40 dB左右,且该隐写图像可有效抵抗RS(Regular Singular)隐写分析、像素差直方图(PDH)隐写分析和位平面隐写分析的静态攻击。因此,所提方案有效提高了对原始图像的嵌入效率,同时具有良好的抗检测能力。
Aiming at the problem of low embedding efficiency and anti-detection capability when using Reversible Data Hiding(RDH)to protect data in scenarios with large data volume delivery,an efficient reversible data hiding scheme based on two-dimensional modulo operations was proposed.Firstly,a larger amount of information was embedded in smaller modified pixel values by modulo operations,then the number of embedded bits was increased by combining with an enhanced base conversion system,and finally the reversibility was conferred by using the halving method in combination with a double image.Simulation experiments conducted on the USC-SIPI standard image library show that the Peak Signal-to-Noise Ratio(PSNR)value of the steganographic image by the proposed scheme is about 40 dB when embedding up to 1 million bits of secret information,and the steganographic image can effectively resist the static attacks of RS(Regular Singular)steganalysis,Pixel-Difference Histogram(PDH)steganalysis,and bit-plane steganalysis.Therefore,the proposed scheme effectively improves the embedding efficiency of the original image,and has good anti-detection capability at the same time.
