Abstract:Aiming at the low capacity of steganography method of image carrier， a generative carrier-free information steganography method based on Wasserstein distance was proposed in this paper，which core model was Generative Adversarial Network（GAN）.Firstly，a specific information-noise mapping matrix that supporting customization was proposed.On this basis，specific information was re-encoded as noise fragments and inputted into the pre-trained WGAN.Finally，the network outputted a visualization image that contained specific information.The experimental results showed that the proposed steganography method could effectively improve the anti-detection efficiency and reduce the number of steganographic images while increasing the capacity of the generative information steganography.In addition，the proposed method could be implemented based on a relatively simple network structure and did not depend too much on system performance and resources，and had preferable practicability.
