This paper targets to search so-called good generators by doing a brief survey over the
generators developed in the history of pseudo-random number generators (PRNGs), verify …

Chaos game representation (CGR), a milestone in graphical bioinformatics, has become a
powerful tool regarding alignment-free sequence comparison and feature encoding for …

In order to secure the exchanged medical images in telemedicine, we propose in this work
two blind watermarking approaches for the medical images protection. In the first scheme a …

The design and utilization of suitable fractal structures is one of the prominent areas of
security for the protection of digital data. This paper proposes a generalized fusion fractal …

Millions of confidential images are transmitted every day by people through the multimedia
systems of the internet. Such confidential information in the images may be belong to the …

In order to contribute to the security of medical image, we present in this paper a blind and
robust watermarking technique that allows the integration of the electronic patient's record …

Watermarking is one of the techniques used to protect multimedia data, and images in
particular, from malicious attacks by inserting a signature into these images. However …

In this paper; we propose two new substitution schemes for digital audio watermarking
based on the Fourier transform. The integration of the watermark will be performed by …

In the last two decades, the use of chaotic iterative maps in cryptographic systems,
especially chaotic hash functions, has been expanding. Sensitivity to small changes in initial …

In this paper, using a new two-dimensional complex map, a secure video watermarking
system is presented. Standard analyzes have been performed to analyze a dynamical …
