“…A feature-based watermarking scheme was first proposed in [5] where the authors use the Mexican Hat wavelet scale interaction to extract features in the image that can resist a series of attacks which makes them suitable to be used as emplacement to insert and to extract the mark. Another content-based approach in [6] uses a reworked copy of the traditional Harris corner detector. The reworked copy calculates the corner response function within a circular window originate from the image centre and covers the largest area of it to resist image centre based rotation attacks.…”

Nowadays, image content is frequently subject to different malicious manipulations. To protect images from this illegal manipulations computer science community have recourse to watermarking techniques. To protect digital multimedia content we need just to embed an invisible watermark into images which facilitate the detection of different manipulations, duplication, illegitimate distributions of these images. In this work a robust watermarking technique is presented that embedding invisible watermarks into colour images the singular value decomposition bloc by bloc of a robust transform of images that is the Radial symmetry transform. Each bit of the watermark is inserted in a bloc

“…Contrariwise, invisible watermarks are used in digital image applications, where watermarking objectives are to addressing security issues of the images. Like various digital image applications [68][69][70][71][72][73][74][75][76], invisibility of the watermark appears to be the main interest in the research of medical imaging [8-10, 12, 13, 41, 77-79].…”

“…In a robust watermarking, a watermark usually carries information regarding the owner in order to validate who the image belongs to (e.g., which person, which institute or organization, etc.). Thus, these watermarking schemes are being used for content authentication purposes in various digital image applications (e.g., copyright protection) [68,73,79,[82][83][84][85][86]. Semi-fragile and fragile watermarks are being used to carry much information about itself, its owner's metadata, its distribution, etc., and are thus used for annotation (e.g., hiding ETR or EPR, etc.)…”

A Review of Medical Image Watermarking Requirements for Teleradiology

Teleradiology allows medical images to be transmitted over electronic networks for clinical interpretation and for improved healthcare access, delivery, and standards. Although such remote transmission of the images is raising various new and complex legal and ethical issues, including image retention and fraud, privacy, malpractice liability, etc., considerations of the security measures used in teleradiology remain unchanged. Addressing this problem naturally warrants investigations on the security measures for their relative functional limitations and for the scope of considering them further. In this paper, starting with various security and privacy standards, the security requirements of medical images as well as expected threats in teleradiology are reviewed. This will make it possible to determine the limitations of the conventional measures used against the expected threats. Furthermore, we thoroughly study the utilization of digital watermarking for teleradiology. Following the key attributes and roles of various watermarking parameters, justification for watermarking over conventional security measures is made in terms of their various objectives, properties, and requirements. We also outline the main objectives of medical image watermarking for teleradiology and provide recommendations on suitable watermarking techniques and their characterization. Finally, concluding remarks and directions for future research are presented.
