In this paper, a digital image encryption algorithm is proposed based on the generalized
model of the chaos game. The chaos game is a well-known fractal, which acts as a pseudo …

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 …

In this paper, a novel watermarking approach is proposed to provide enhanced tampering
localization and self-recovery. A cross chaotic map is used to confuse the blocks generated …

Geometric distortion is known as one of the most difficult attacks to resist, for it can
desynchronize the location of the watermark and hence causes incorrect watermark …

In the modern world, high-bandwidth internet access has led to the theft of all types of digital
data, including digital video, and their illegal distribution. The digital video watermarking …

This paper proposes a local multi-watermarking method based on robust and adaptive
feature extraction. The Robust and Adaptive Feature Detector based on DAISY Descriptor …

In this paper, we suggest a new steganographic spatial domain algorithm based on a single
chaotic map. Unlike most existing steganographic algorithms, the proposed algorithm uses …

Reversible watermarking can be applied to the protection for important digital media, such
as medical and military image, it allows the watermark to be extracted and the original image …

Image steganography is a technique to hide secret information in an image without leaving
any apparent evidence of image alteration. Hiding capacity, perceptual transparency …

This work focuses on enhancing security for transmitted e-documents, such as e-stamp
papers, within wireless environments through dynamic authentication using variable circular …
