The ability of communicating the information and hiding secret information has gained much
advancement in the field of image processing. Watermarking in the image processing hides …

With the growing use of the digital world and its associated challenges, the use of digital
watermarking is a popular and appropriate way of protecting digital content against illegal …

This book is about the simulation and modeling of novel chaotic systems within the frame of
fractal-fractional operators. The methods used, their convergence, stability, and error …

Recent evidences suggest that complex behavior such as chaos can be observed in a
nonlinear system with stable equilibria. However, few studies have investigated chaotic …

Digital image watermarking plays an important role in digital content protection and security
related applications. Embedding watermark is helpful to identify the copyright of an image or …

Integrity protection is one of the security mechanisms used to prevent the originality of the
content from illegal manipulation. In this paper, the authors have proposed an efficient …

The conventional image hiding scheme based on computational ghost imaging (CGI) has
low-quality reconstructed watermark and unsatisfied security. In this paper, a high …

In this paper, we study the dynamic evolution of chaotic and oscillatory waves arising from
dissipative dynamical systems of elliptic and parabolic types of partial differential equations …

For the past five years there has been much attention to systems with uncountable equilibria.
This work introduces a new system with an infinite number of equilibrium points. It is worth …

As a primary method, image encryption is widely used to protect the security of image
information. In recent years, image encryption pays attention to the combination with DNA …
