Ashima Anand, Amit Kumar Singh, Huiyu Zhou · Institution of Engineering and Technology eBooks · 2022
With the growth and popularity of the utilization of medical images in smart health care, the large amount of health records and related images, which needs to be transmitted, is consistently increasing. However, exchanging these medical records among hospitals, doctors, and medical team faces many challenges associated to ownership conflicts, data security, and privacy. Medical image watermarking is an effective copyright protection tool by embedding copyright/secret information/logo into the carrier image. This chapter provides a detailed overview of watermarking along with its characteristics and current applications. We then provide a comparative survey of the different state-of-the-art approaches along with their merits and limitations. We further summarized each of the state-of-the-art approaches in detail, including objectives, goals, dataset used, evaluation metrics, and weaknesses, and discussed the recent challenges and their possible solutions. We believe this chapter will provide the readers a comprehensive insight to the field of watermarking research in the health care domain.
