Steganography and steganalysis are two interrelated aspects of the field of information
security. Steganography seeks to conceal communications, whereas steganalysis aims to …

Audio steganography is the process of hiding a message inside an audio container. This
study aims to present a systematic review of audio steganography methods. Existing reviews …

To improve a recently developed mel-cepstrum audio steganalysis method, we present in
this paper a method based on Fourier spectrum statistics and mel-cepstrum coefficients …

Multimedia data mining, particularly feature selection (FS), has been successfully applied in
recent classification and recognition works. However, only a few studies in the contemporary …

This article presents a second-order derivative-based audio steganalysis. First, Mel-
cepstrum coefficients and Markov transition features from the second-order derivative of the …

During the last decade, audio information hiding has attracted lots of attention due to its
ability to provide a covert communication channel. On the other hand, various audio …

MP3, one of the most widely used digital audio formats, provides a high compression ratio
with faithful quality. The widespread use enables MP3 audio files to become excellent …

We investigate the use of chaotic-type features for recorded speech steganalysis.
Considering that data hiding within a speech signal distorts the chaotic properties of the …

Steganography is the process of hiding messages inside an object known as a carrier. The
idea is establishing a covert communication channel where messages go unnoticed by …

Recently, merging signal processing techniques with information security services has
drawn a lot of attention. Steganography and steganalysis are among those trends. Like their …
