Dhanush Polisetty, Syed Wajahat Abbas Rizvi . GAN-based Adaptive Image Steganography. International Journal of Computer Applications. 187, 6 ( May 2025), 45-50. DOI=10.5120/ijca2025924951
Steganography through image hiding is one of the significant methods of secure communication. In the method of digital image hiding, the secret information is concealed without compromising its perceptibility. Classical steganographic techniques such as LSB-based approaches and DCT-based techniques face severe challenges regarding limited embedding capacity and susceptibility to steganalysis attacks. Here, a novel GAN-based steganography model that tries to find a balance between these two requirements and robustness against attacks has been proposed in this paper. We design GAN architecture for embedding secret data into the cover images such that these are left perceptually unchanged, and a discriminator that ensures the stego-images are indistinguishable from natural ones. The model is trained with a custom loss function that considers adversarial learning, perceptual quality, and embedding efficiency. Experimental assessment is performed on benchmark datasets, including COCO and Image Net, using the metrics of PSNR (Peak Signal-to-Noise Ratio), SSIM (Structural Similarity Index), and robustness. The results show that our GAN-based method surpasses traditional steganographic methods in terms of imperceptibility and resistance to steganalysis. Furthermore, the model remains robust against standard image transformations such as compression, noise addition, and cropping. This paper showcases the prospect of deep learning-driven steganography in the pursuit of improved data security and further proposes future improvements for real-world applications in secure communication and digital watermarking.
