Abstract

The progress in data transmission technology has underscored the significance of safeguarding information, particularly with regards to confidentiality. Researchers have therefore dedicated their attention to tackling this concern by introducing various techniques for protecting data confidentiality, including cryptography and steganography. Steganography, a data hiding method that has showcased better results in data security in images, gained significant attention from information security practitioners. Nevertheless, the existing methods show a significant tradeoff between the payload capacity and the stego image's quality, making them not applicable to sensitive domains such as military and medical. In this work, we propose a new steganography method working in medical images based on difference expansions to optimize the alleviation of the imbalance between the payload size and the imperceptibility of the stego image. Our experimental results achieve the best performance of a psnr of 75.1312 dB and the best psnr capacity of 0.6831. Our results showed an improvement in payload capacity from 0.4835 bpp by comparing the existing method to 0.6705 bpp with the same cover image labeled 'Leg'.
