The aim of medical image watermarking is to preserve the integrity of a medical image after embedding the required data. With the evolution of the internet in almost every domain of life, telemedicine is a word that has gained popularity in the last four to five years. This article provides an overview of the research that are carried out on medical image watermarking techniques in the last several years. To carry out this survey, research papers on different techniques for medical image watermarking have been studied from Google Scholar, ACM, IEEE, etc. 89% of the data is considered from reputed journals, and the rest of the papers are from different conferences, and book chapters. This article describes the comparison between various techniques used for medical image watermarking. It helps out in identifying the gaps between the different techniques so that a naive approach can be designed to get better results.
