Survey of Medical Image Watermarking Algorithms
K. A. Navas, M. Sasikumar · 2007
Watermarking in medical images is a new area of research and some works in this area have been reported world wide recently. Most of the works are on the tamper detection of the images and embedding of the Electronics Patient Record (EPR) data in the medical images. Watermarked medical images can be used for transmission, storage or telediagnosis. Tamper detection watermarks are useful to locate the regions in the image where some manipulations have been made. EPR data hiding in images improves the confidentiality of the patient data, saves memory storage space and reduce the bandwidth requirement for transmission of images. This paper discusses various aspects of medical image watermarking and makes a review of various watermarking algorithms originally proposed for medical images.
