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
