An extensive literature survey on medical image steganography

摘要

Steganography which is an art as well as a sci-ence of invisible transmission arrived as a saviour by providing utmost security through various techniques. Medical Image Steganography is a special subcategory of Image Steganography. It has come a long way to make the transmission of medical images more and more safe and to make sure that the diagnostic reading of the image does not get affected. Security is the most crucial aspect of communication in today's world. While sharing documents on the internet, one needs assurance of privacy and secrecy, as these days' communication is not only restricted to chatting but plays a vital role in almost all sectors. This paper discusses various algorithms used in medical image steganography and analyse the best out of all based on various characteristics of the algorithms like robustness, PSNR (Peak signal-to-noise ratio) value, MSE (Mean Squared Error) value, payload capacity etc.
