Abstract

Image steganography is a technique that hides secret information into the cover image to protect information security. The current image steganography is mainly to embed a smaller secret image in an area such as a texture of a larger-sized cover image, which will cause the size of the secret image to be much smaller than the cover image. Therefore, the problem of small steganographic capacity needs to be solved urgently. This paper proposes a steganography framework that combines image compression. In this framework, the Vector Quantized Variational AutoEncoder (VQ-VAE) is used to achieve the compression of the secret image. The compressed and reconstructed image is visually indistinguishable from the original image and facilitates more embedded data information later. Finally, the compressed image is transmitted to a SegNet deep neural network that contains a set of encoders and decoders to achieve image hiding and extraction. Experimental results show that the steganographic framework guarantees the quality of steganography while its relative steganographic capacity reaches 1. Besides, Peak Signal-to-Noise Ratio (PSNR) and Structural Similarity Index (SSIM) values can reach 42 dB and 0.94, respectively.
