Abstract:
Telemedicine is a well-known application, where enormous amount of medical data need to be
securely transfer over the public network and manipulate effectively. Medical image
watermarking is an appropriate method used for enhancing security and authentication of
medical data, which is crucial and used for further diagnosis and reference. This paper
discusses the available medical image watermarking methods for protecting and authenticating
medical data. The paper focuses on algorithms for application of watermarking technique on
Region of Non Interest (RONI) of the medical image preserving Region of Interest (ROI). The
medical images can be transferred securely by embedding watermarks in RONI allowing
verification of the legitimate changes at the receiving end without affecting ROI.
