Due to exponential growth of digital world the online data is also drastically increasing. This
multimedia data may contain text, video, audio, and images. After the Covid-19 pandemic …

In this paper, two logistic-map based fragile image watermarking schemes are proposed.
The first scheme is a conventional irreversible, whereas the second scheme is a reversible …

Image watermarking is an effective and promising technology. Robust watermarks, resistant
to various attacks, allow authors and owners of digital images to protect their rights to digital …

In this study, a high-capacity QR decomposition (QRD) based blind watermarking algorithm
with artificial intelligence (AI) technologies for color images was proposed. Watermarking …

Compared with binary and grayscale watermark, the color watermark has a larger amount of
information, which makes color blind watermarking algorithms more challenging in terms of …

Medical data is transferred between hospitals and healthcare providers via telemedicine to
improve patient care. This transfer exposes medical data to a number of security risks, and …

Digital watermarking schemes based on a single value of embedding strength do not take
into account the local characteristics of the host signal for watermark embedding …

This paper proposes an encryption-based image watermarking scheme using a combination
of second-level discrete wavelet transform (2DWT) and discrete cosine transform (DCT) with …

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

Increasing the robustness, reliability and security of the digital image watermarking methods
against image processing and geometrics attacks are a key issues especially for image …
