SECURE TELEMEDICINE TRANSMISSION USING WATERMARKING TECHNIQUES

Abstract

Under the growing numbers of medical digital images and the need to share them in between specialists and hospitals for better and more accurate diagnosis require that patient’s privacy should be protected. As a matter of this, there is a need for medical image watermarking. However, it needs to be performed with special care for two reasons. Firstly, the watermarking process or procedure can’t compromise the quality of the image. Secondly, confidential patient information embedded within the image should be fully retrievable without risk of error after image decompressing. Despite extensive research undertaken in this field, there is still no method available to fulfill all the requirements of medical image watermarking. This study aims to provide a useful survey on watermarking and offers clear perspective for interested researchers by analyzing the strengths and weaknesses of different existing methods such DWT with SVD or without the SVD.
