“…The experimental results showed the effectiveness of the algorithm in providing the authenticity, integrity and tamper localization requirements with PSNR greater than 32.9232 dB. In [34] DFT based watermarking method is proposed to avoid detachment of medical images from their corresponding EPR data. The watermark pattern is produced by combining DICOM metadata and encryption techniques.…”

Telemedicine is an emerging science that can help in solving the modern global health problems. Exchanging medical images and Electronic Patient Records (EPR) between clinicians, specialists, and radiologists provides a platform for discussing and consulting diagnostic and therapeutic problems.Using Information and Communication Technologies (ICT) in the transmission of medical information for improving healthcare access, diagnosis, and treatment requires various means for security and privacy issues, since, digital information can be easily attacked to be duplicated and manipulated. Digital watermarking is a data hiding technique which used for improving the security of various multimedia applications and extensively investigated to protect the privacy of patients through telemedicine systems. This paper aims to provide a useful preview on telemedicine and the using of digital watermarking in this field.

“…Their results demonstrated significant robustness against amplitude modulation, the print-scan process (PS), half-toning, the print-cam process (PC), cropping, and attacks from the StirMark benchmark software. Cedillo-Hernandez et al [89] studied a robust watermarking method in the DFT domain for managing medical images, which ensured high robustness and preserved the quality of the watermarked images. The proposed method inserts the watermark into the magnitude spectrum of the middle frequencies of the DFT of the original medical image.…”

Digital image authentication is an extremely significant concern for the digital revolution, as it is easy to tamper with any image. In the last few decades, it has been an urgent concern for researchers to ensure the authenticity of digital images. Based on the desired applications, several suitable watermarking techniques have been developed to mitigate this concern. However, it is tough to achieve a watermarking system that is simultaneously robust and secure. This paper gives details of standard watermarking system frameworks and lists some standard requirements that are used in designing watermarking techniques for several distinct applications. The current trends of digital image watermarking techniques are also reviewed in order to find the state-of-the-art methods and their limitations. Some conventional attacks are discussed, and future research directions are given.

“…This is because the phase conveys essential information on the image [35,85]. Embedding the watermark in the magnitude part of DFT [34] generates lower Other valuable properties of the magnitude component are shift and translation invariant. With these properties, the embedded watermark will not be affected by a translation or shift in the spatial domain.…”

Watermarking Techniques used in Medical Images: a Survey

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.
