摘要:

针对图像隐写中载体修改会留有修改痕迹的问题,文章提出一种基于数字化卡登格的图像隐写方案。首先自动生成数字化卡登格,作为信息隐写和提取的密钥;其次以空白图像作为载体,根据数字化卡登格的区域填充秘密信息;在整个隐写过程保持秘密消息不变的情况下,再利用深度生成模型补全受损的图像,生成具有自然语义的含密图像。文章方案不受载体类型的限制,还可以扩展到其他数字媒体。实验结果表明,新的图像隐写方案具有良好的可行性,相比其他隐写方法,文中方案在实际通信中安全性较高。

Abstract:

In order to solve the problem that the carrier modification in image steganography will leave the modification trace, this paper proposes an image steganography scheme based on digital Cardan Grille. The scheme first generates the digital Cardan Grille automatically as the key of information steganography and extraction. Secondly, the blank image is used as the carrier to fill in the secret information according to the area of digital Cardan Grille. Under the condition that the secret message is kept unchanged in the whole steganography process, the damaged image of the model is generated by depth to generate the stego image with natural semantics. The results of experiments on CelebA dataset and LUSN dataset show that the new steganography scheme is feasible. Compared with other steganographic methods, this scheme is more secure in actual communication.

Key words: image steganography, digital Cardan Grille, semantic completion, GAN
