The mainstream adaptive steganography algorithms often cannot transmit secret messages
correctly when stego images suffer from JPEG compression. In this respect, researchers …

The frequency of digital data transmission or sharing online has heavily increased due to the
number of people regularly accessing the internet. This guide explores how easily copyright …

In this paper, an image watermarking algorithm with high security and robustness using
matrix decomposition and Gyrator transform is proposed, which is developed in the invariant …

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 this paper, we propose a novel robust blind color image watermarking method, namely
SMLE, that allows to embed a gray-scale image as watermark into a host color image in the …

Data security is a main concern in everyday data transmissions over the Internet. A possible
solution to guarantee secure and legitimate transaction is via hiding a piece of tractable …

Recently, data hiding scheme developed rapidly. But its permanent distortion does not
satisfy some sensitive applications. Accordingly, reversible data hiding (RDH) has …

This paper presents a new robust multiplicative watermark detector. Due to the strong
robustness against various attacks, polar harmonic Fourier moment (PHFM) magnitudes are …

Imperceptibility and robustness are two main requirements of any image watermarking
systems to guarantee desired functionalities, but there is a tradeoff between them from the …

The illegal duplication of digital copies became easier because of increased communication
speed and rapid growth of internetworked multimedia systems. So it is required to …
