In this proposed work, a dual image watermarking algorithm is used to protect the data
against copyright violations. In this work, the DICOM image is used as a host image. Two …

Image quality assessment (IQA) is an important task of image processing and has diverse
applications, such as image super-resolution reconstruction, image transmission and …

The paper addresses the issue of ensuring the authenticity and copyright of medical images
in telemedicine applications, with a specific emphasis on watermarking methods. While …

Due to the differences of observation equipment and technical means, the size of the color
digital image is not the same. In addition, most of digital watermarking methods used to …

In this article, we propose a key secret-sharing technology based on generative adversarial
networks (GANs) to address three major problems in the blockchain: 1) low security; 2) hard …

With the rapid progression in Internet technologies, content authentication and copyright
concerns have increased exponentially. To overcome these challenges, this paper proposes …

Watermarking scheme is not helpful in conveying the original image continually so as
identifying the owner's mark from the watermarked image. In the current situation, our …

In this paper, a novel image zero-watermarking scheme against rotation attacks is proposed
based on nonsubsampled pyramid decomposition (NSPD) and discrete cosine transform …

It still remains a challenging problem to improve both of the imperceptibility and robustness
for the digital image watermarking task. In this study, a color image watermarking scheme is …

In order to contribute to the security of medical image, we present in this paper a blind and
robust watermarking technique that allows the integration of the electronic patient's record …
