The ever-growing numbers of medical digital images and the need to share them among specialists and hospitals for better and more accurate diagnosis require that patients’ privacy be protected. As a result of this, there is a need for medical image watermarking (MIW). However, MIW needs to be performed with special care for two reasons. Firstly, the watermarking procedure cannot compromise the quality of the image. Secondly, confidential patient information embedded within the image should be flawlessly retrievable without risk of error after image decompressing. Despite extensive research undertaken in this area, there is still no method available to fulfill all the requirements of MIW. This paper aims to provide a useful survey on watermarking and offer a clear perspective for interested researchers by analyzing the strengths and weaknesses of different existing methods.read more

Robust Object-Based Watermarking Using SURF Feature Matching and DFT Domain
TL;DR: A robust object-based watermarking method, in which the watermark is embedded into the middle frequencies band of the Discrete Fourier Transform magnitude of the selected object region, altogether with the Speeded Up Robust Feature (SURF) algorithm to allow the correct watermark detec- tion, even if the watermarked image has been distorted.

Verification of image content integrity by using dual watermarking on wavelets domain
TL;DR: A fragile watermarking scheme, which embeds dual watermarks (one is naturally fragile and the other is actually robust) in JPEG-2000 compressed images with ROI (region of interest) selection, which is scalable in view of detecting attack's intension as well as accuracy in localizing the tampered areas.
