“…In contrast, separation of ROI and RONI in medical images is not straightforward and may require the interaction/approval of doctor/radiologist. In addition, making such separation is sometimes very difficult, although it is applied in several watermarking schemes [9,12,77]. Besides, developing reversible watermarking is promising for medical image application with taking no risk for sacrificing the diagnostic accuracy, although computational properties may incur additional complexity in different processing domains.…”

“…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.…”

“…These requirements are being achieved by different conventional measures, which are thought to be incapable of providing the required security of the electronic radiology information in the PACS/RIS-based teleradiology [5][6][7]. On the other hand, recent studies show the possibility of using digital watermarking for improving security in teleradiology [8][9][10][11][12][13][14][15][16].…”

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.

“…For instance, in [27,28], reversible and non-reversible methods are used for embedding the watermark in ROI and RONI, respectively, and in [29,30], fragile and robust methods are used for embedding the watermark in ROI and RONI, respectively.…”

“…For example, in [14,16,18,20,22,25,[31][32][33][34], the ROI is manually assigned by defining a rectangle box around it, and in [15,17,21,27,28], the polygonal ROI is specified manually. In automatic ROI partitioning [19,23,24,26,29,30], there are some problems which will be highlighted later in this paper.…”

A Heuristic Automatic and Robust ROI Detection Method for Medical Image Warermarking

2015

This paper presents an automatic region of interest (ROI) segmentation method for application of watermarking in medical images. The advantage of using this scheme is that the proposed method is robust against different attacks such as median, Wiener, Gaussian, and sharpening filters. In other words, this technique can produce the same result for the ROI before and after these attacks. The proposed algorithm consists of three main parts; suggesting an automatic ROI detection system, evaluating the robustness of the proposed system against numerous attacks, and finally recommending an enhancement part to increase the strength of the composed system against different attacks. Results obtained from the proposed method demonstrated the promising performance of the method.
