With the advent of Internet, images and videos are the most vulnerable media that can be
exploited by criminals to manipulate for hiding the evidence of the crime. This is now easier …

This survey presents a brief discussion of different aspects of digital image watermarking.
Included in the present discussion are these general concepts: major characteristics of …

The outbreak of digital devices on the Internet, the exponential diffusion of data (images,
video, audio, and text), along with their manipulation/generation also by artificial intelligence …

This paper presents a robust watermarking approach for hiding grayscale watermarks into
digital images. Plugging the codebook concept into the singular value decomposition (SVD) …

In this paper, we propose a novel algorithm for pseudo random number sequence generator
based on the samples of Chen chaotic system. The proposed algorithm can be used to …

In this article, a novel sensitive encryption scheme to secure the digital images based on the
Zaslavsky chaotic map is proposed. We employ the Zaslavsky chaotic map as a pseudo …

A robust copyright protection scheme for digital image is proposed in the paper. In the
proposed scheme, the watermark does not require to be embedded into the protected image …

A wavelet-based copyright-proving scheme that does not require the original image for logo
verification is proposed in this paper. The scheme is strong enough to resist malicious …

With the rapid growth of numerous multimedia applications and communications through
Internet, secret image sharing has been becoming a key technology for digital images in …

In this paper we propose a novel and efficient hardware implementation of an image
watermarking system based on the Haar Discrete Wavelet Transform (DWT). DWT is used in …
