In this paper, a new robust steganography algorithm based on discrete cosine transform
(DCT), Arnold transform and chaotic system is proposed. The chaotic system is used to …

Evolutionary computation algorithms represent a class of stochastic methods that can be
applied to a wide set of different complex optimization problems. Recently, the combination …

Image fusion process consolidates data and information from various images of same sight
into a solitary image. Each of the source images might speak to a fractional perspective of …

This paper proposes a novel tamper detection, localization, and recovery scheme for
encrypted images with Discrete Wavelet Transformation (DWT) and Compressive Sensing …

Digital watermarking is the process of embedding secret information into a digital signal
which may be used to verify its authenticity or the identity of its owners. In this paper, a non …

Digital watermarking is the process of embedding secret information into a digital signal

The modern era of digital communication facilities bring digital watermarking techniques
which is required to copyright and authenticate owner's information which further tracks …

Earlier the digital watermarking was evaluated according to imperceptibility, capacity and
robustness. In this paper based on security considerations we address a new secure …

Nowadays, most prevailing approaches to advanced audio coding (AAC) steganography
are content non-adaptive which have low embedding capacity and poor security. In this …

In this paper, a digital image watermarking method in YCoCg-R color space is proposed that
uses YCoCg-R color space as a new working environment and coefficients Relation for …
