Digital images are everywhere—from our cell phones to the pages of our online news sites.
How we choose to use digital image processing raises a surprising host of legal and ethical …

In this paper, we propose an extension of the spatial rich model for steganalysis of color
images. The additional features are formed by three-dimensional co-occurrences of …

This tutorial paper reviews the theory and design of codes for hiding or embedding
information in signals such as images, video, audio, graphics, and text. Such codes have …

Steganography is the art of secret communication and steganalysis is the art of detecting the
hidden messages embedded in digital media using steganography. Both steganography …

The contribution of this paper is two-fold. First, we describe an improved version of a blind
steganalysis method previously proposed by Holotyak et al. and compare it to current state …

Blind steganalysis techniques detect the existence of secret messages embedded in digital
media when the steganography embedding algorithm is unknown. This paper presents a …

In the last few years, we have seen many new and powerful steganography and
steganalysis techniques reported in the literature. In the following tutorial we go over some …

There are many detectors for simple Least Significant Bit (LSB) steganography in digital
images, the most sensitive of which make use of structural or combinatorial properties of the …

The difficult task of steganalysis, or the detection of the presence of hidden data, can be
greatly aided by exploiting the correlations inherent in typical host or cover signals. In …
