摘要:

针对信息隐藏中修改载体嵌入信息的方法会留有痕迹,从根本上难以抵抗统计分析算法检测的问题,文章提出一种基于生成对抗网络的图像隐写方案,通过生成更合适的载体图像来提高信息隐藏的安全性,能够有效抵抗隐写分析算法的检测。该方案提出的策略是联合生成对抗网络和传统信息隐藏技术,将生成式载密图像和传统式载密图像作为输入,进行迭代优化,使生成器生成的图像更适合作为载体信息。与SGAN和SSGAN方案相比,该方案使得攻击者在隐写分析错误率上分别提高了9%和4.1%。实验结果表明,该方案在抗隐写分析和安全性指标上明显优于对比方案。

Abstract:

Focused on the issue that information-hidden carriers will leave traces of modification, and it is fundamentally difficult to resist the statistical steganalysis algorithm detection. A new security steganography model based on Generative Adversarial Networks (GAN) is proposed.By generating more appropriate carrier information to ensure the security of information hiding and improving the imperceptibility, we can effectively resist the steganalysis algorithm detection.The proposed strategy is to jointly generate the anti-network and traditional information hiding, and use the “generated” image and the “traditional” image as the discriminator input, and iteratively optimizes it,which make the image generated by the generator more suitable as carrier information. Compared with SGAN and SSGAN, this model reduces the detection accuracy of steganalysis by 9% and 4.1% respectively. Experimental results show that the new scheme is superior to the contrast algorithm in Anti-steganography analysis and security indicators.
