Query: Spatial Image Steganography Based on Generative Adversarial Network   With the recent development of deep learning on steganalysis, embedding
secret information into digital images faces great challenges. In this paper, a
secure steganography algorithm by using adversarial training is proposed. The
architecture contain three component modules: a generator, an embedding
simulator and a discriminator. A generator based on U-NET to translate a cover
image into an embedding change probability is proposed. To fit the optimal
embedding simulator and propagate the gradient, a function called
Tanh-simulator is proposed. As for the discriminator, the selection-channel
awareness (SCA) is incorporated to resist the SCA based steganalytic methods.
Experimental results have shown that the proposed framework can increase the
security performance dramatically over the recently reported method ASDL-GAN,
while the training time is only 30% of that used by ASDL-GAN. Furthermore, it
also performs better than the hand-crafted steganographic algorithm S-UNIWARD.
