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

Nowadays, the prevailing detectors of steganographic communication in digital images
mainly consist of three steps, ie, residual computation, feature extraction, and binary …

We describe a novel general strategy for building steganography detectors for digital
images. The process starts with assembling a rich model of the noise component as a union …

Today, the most accurate steganalysis methods for digital media are built as supervised
classifiers on feature vectors extracted from the media. The tool of choice for the machine …

This paper presents a complete methodology for designing practical and highly-
undetectable stegosystems for real digital media. The main design principle is to minimize a …

This paper presents a novel method for detection of steganographic methods that embed in
the spatial domain by adding a low-amplitude independent stego signal, an example of …

Digital audio, video, images, and documents are flying through cyberspace to their
respective owners. Unfortunately, along the way, individuals may choose to intervene and …

Steganography is the art and science of hidden (or covered) communication. In digital
steganography, the bits of image, video, audio and text files are tweaked to represent the …

This paper models the messages embedded by spatial least significant bit (LSB) matching
as independent noises to the cover image, and reveals that the histogram of the differences …

The term, steganography, comes from Greek and means “covered writing”(Johnson and
Jajodia, 1998a; Petitcolas et al., 1999). The intent of steganography is to hide a message in …
