Steganography and steganalysis are the prominent research fields in information hiding
paradigm. Steganography is the science of invisible communication while steganalysis is …

This paper presents a new efficient embedding algorithm in the wavelet domain of digital
images based on the diamond encoding (DE) scheme. Current discrete wavelet transform …

Image steganography is a technique of hiding secret data into a cover image and so as to
prevent the intruders from accessing the secret data. The efficiency of image steganography …

The fundamental requirements of information hiding systems are good visual quality, high
hiding capacity, robustness and steganographic security. In this paper, we propose a new …

Transmitting data over a public network—for instance, the Internet—necessitates increasing
the security of data communications, especially within the extremely sensitive category of file …

Medical images are of high importance and patient data must be kept confidential. In this
chapter, we discuss a new hybrid transform domain technique for medical image …

Data hiding is a technique for sending secret information under the cover of the digital
media. It is usually used to protect privacy and sensitive information when such information …

Steganography is the science of hiding secret message in an appropriate digital multimedia
in such a way that the existence of the embedded message should be invisible to anyone …

Image steganography is the art of concealing secret information in images in a way that is
imperceptible to unauthorized parties. Recent advances show that is possible to use a fixed …

In this paper, we present a 2D Logistic-Sine-Cosine map (2D-LSCM) which is based on the
classical 2D Logistic, Sine and Cosine maps. Performance analysis shows that it has larger …
