“…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.) [15,55,57,61,65,87] and integrity control (e.g., tamper detection and recovery) [8,59,[88][89][90].…”

“…A digital medical image application is therefore one of the prospective target areas of using digital watermarking. Studies show that various watermarking schemes can be used in teleradiology for (1) origin/content authentication [9,13,41,107,[113][114][115][116][117][118][119], (2) EPR annotation [57,65,88,[120][121][122], and (3) tamper detection and recovery of medical images [8,14,59,123,124]. Some important aspects of medical image watermarking schemes for their different objectives are summarized below.…”

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.

“…However, the LSB based self-restoration watermark is fragile and could be easily distorted. To reduce the size of the restoration watermark and to improve the robustness, Region of Interest (ROI) self-restoration schemes were proposed in [10,11]. The two restoration schemes were shown more robust against JPEG compression.…”

“…Watermarking, on the other hand, is an image authentication/protection technique that embeds invisible information into an image. Unfortunately, most of the existing watermarking and digital signature based image authentication systems can detect malicious tampering successfully; however there are few system that have recovery capability the tampered region without original image [6], [7]. In [6], a Slant Transform (SLT) based semi-fragile watermarking scheme is proposed.…”

In this paper, a block wise image authentication scheme using a semi-fragile watermark is proposed. The proposed scheme determines integrity of the image, detecting regions suffered some content modifications and altered region can be recovered without the original image. In the proposed scheme, the original image is divided into two regions: Region of Interest ROI, which is important region that requires protection against malicious modification and Region of Embedding ROE, which is the rest of the image where watermark sequence is embedded. The proposed scheme is evaluated from the several points of view: watermark imperceptibility, accuracy of tamper area detection, quality of recovered regions and robustness to nointentional manipulations, such as JPEG compression. Experimental results show excellent performance of the proposed scheme.
