摘要:

目前,已有大量的工作将卷积神经网络引入到隐写分析中,并超越了传统的隐写分析算法。这些工作显示了深度学习在信息隐藏领域的改进潜力。也有几个基于深度学习做图像隐写的作品,但这些作品在容量、不可见性和安全性上还存在问题。在本文中,我们提出了一种新的CNN架构命名为\isgan隐藏秘密灰度图像到彩色封面图像的发送端和准确地提取秘密图像的接收端。我们的工作有三个贡献:(i)我们通过将秘密图像仅隐藏在覆盖图像的Y通道中来提高不可见性;(ii)我们引入生成对抗网络,通过最小化隐藏图像和自然图像的经验概率分布之间的差异来加强安全性。(iii)为了更好地与人类视觉系统相关联,我们构造了一个更适合隐写的混合损失函数,以生成更真实的隐写图像,并揭示出更多更好的秘密图像。实验结果表明,ISGAN在LFW、Pascal VOC 2012和ImageNet数据集上均能达到最佳性能。

英文摘要:

Nowadays, there are plenty of works introducing convolutional neural networks (CNNs) to the steganalysis and exceeding conventional steganalysis algorithms. These works have shown the improving potential of deep learning in information hiding domain. There are also several works based on deep learning to do image steganography, but these works still have problems in capacity, invisibility and security. In this paper, we propose a novel CNN architecture named as \isgan to conceal a secret gray image into a color cover image on the sender side and exactly extract the secret image out on the receiver side. There are three contributions in our work: (i) we improve the invisibility by hiding the secret image only in the Y channel of the cover image; (ii) We introduce the generative adversarial networks to strengthen the security by minimizing the divergence between the empirical probability distributions of stego images and natural images. (iii) In order to associate with the human visual system better, we construct a mixed loss function which is more appropriate for steganography to generate more realistic stego images and reveal out more better secret images. Experiment results show that ISGAN can achieve start-of-art performances on LFW, Pascal VOC2012 and ImageNet datasets.
