Review of Image Watermarking Technique for Medical Images

Abstract

This article looks at using watermarking methods in medical images to make them safer and easier to manage. The idea is to protect trustworthiness, honesty, and safe sharing of health records. This paper looks at cases where watermarking has been used well in healthcare systems. Experts stress the main worry of keeping medical records accurate. Watermarking of medical images is an effective way to keep important health data safe and helpful for checking diseases and referencing information in the healthcare system. It explains current health image marking methods, focusing on the Region of Non-Interest (RONI) while keeping the key area safe. As nanoscience and nanotechnology progress, their use in medicine gets more common. Nano technology medical imaging gear gives clear and correct images of people's organs. This is key for finding out what is wrong in medicine. In today's world medicine and changing computers, scientists look at what is inside living things to find illness early and make science-based treatments. Medical images used in research often need to be shared or sent online for many uses like remote care. Telemedicine uses phone and computer science to give healthcare from far away, especially in places that do not have quick medical help. Telemedicine systems often use parts of images called regions of interest (ROI) and areas that are not important (RONI). The ROI is needed for doctors to make decisions about a patient's health. This paper focuses on about why watermarking medical images is important to keep information safe.
