  In this paper, a new framework for construction of Cardan grille for
information hiding is proposed. Based on the semantic image inpainting
technique, the stego image are driven by secret messages directly. A mask
called Digital Cardan Grille (DCG) for determining the hidden location is
introduced to hide the message. The message is written to the corrupted region
that needs to be filled in the corrupted image in advance. Then the corrupted
image with secret message is feeded into a Generative Adversarial Network (GAN)
for semantic completion. The adversarial game not only reconstruct the
corrupted image , but also generate a stego image which contains the logic
rationality of image content. The experimental results verify the feasibility
of the proposed method.
