Stego Image

Steganography, the art of hiding information within other data, is experiencing renewed interest, particularly in image and text formats. Current research focuses on improving the capacity and imperceptibility of hidden messages, employing techniques like large language models (LLMs) for text steganography and convolutional neural networks or diffusion models for image steganography, often aiming for lossless recovery of the hidden data. These advancements are driven by the need for secure communication and data protection, with applications ranging from covert communication to protecting sensitive information within multimedia. The development of novel architectures, such as those based on implicit neural representations and order-preserving mechanisms, is pushing the boundaries of both capacity and robustness against detection.
