SteganoGAN: High Capacity Image Steganography with GANs
This addresses the need for high-capacity and undetectable image steganography for secure communication, though it is incremental as it builds on existing GAN techniques.
The paper tackled the problem of hiding binary data in images by proposing a GAN-based steganography method, achieving a state-of-the-art payload of 4.4 bits per pixel while evading detection by steganalysis tools.
Image steganography is a procedure for hiding messages inside pictures. While other techniques such as cryptography aim to prevent adversaries from reading the secret message, steganography aims to hide the presence of the message itself. In this paper, we propose a novel technique for hiding arbitrary binary data in images using generative adversarial networks which allow us to optimize the perceptual quality of the images produced by our model. We show that our approach achieves state-of-the-art payloads of 4.4 bits per pixel, evades detection by steganalysis tools, and is effective on images from multiple datasets. To enable fair comparisons, we have released an open source library that is available online at https://github.com/DAI-Lab/SteganoGAN.
