Fractional Fourier transform (FRFT) is a generalization of the Fourier transform, rediscovered
many times over the past 100 years. In this paper, we provide an overview of recent …

Over the past several decades, digital information science has emerged to seek answers to
the question: can any technique ensure tamper-resistance and protect the copyright of …

The growth of the Internet has fueled the demand for enhanced watermarking and data
hiding technologies and has stimulated research into new ways to implement watermarking …

This paper utilizes deep neural networks for robust digital watermarking and authentication
of speech signals. We present two adversarial neural networks, called embedder and …

Three novel blind watermarking techniques are proposed to embed watermarks into digital
images for different purposes. The watermarks are designed to be decoded or detected …

Embedding of a watermark signal is an interesting research and application field in the
copyright protection of multimedia signals (images, sounds, movies)[1–4]. The goal is to …

In this paper, we proposed a novel blind digital image watermarking algorithm based on the
