Network covert channels are increasingly used to endow malware with stealthy behaviors,
for instance to exfiltrate data or to orchestrate nodes of a botnet in a cloaked manner …

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 …

Describes Information Hiding in communication networks, and highlights their important
issues, challenges, trends, and applications. Highlights development trends and potential …

Steganography is an ancient art that encompasses various techniques of information hiding,
the aim of which is to embed secret information into a carrier message. Steganographic …

The rapid advance and popularization of VoIP (Voice over IP) has also brought security
issues. VoIP-based secure voice communication has two sides: first, for legitimate users, the …

Abstract Information hiding is increasingly used to implement covert channels, to exfiltrate
data or to perform attacks in a stealthy manner. Another important usage deals with privacy …

This paper presents a new steganalysis method that uses a deep belief network (DBN) as a
classifier for audio files. It has been tested on three steganographic techniques: StegHide …

In this study, the authors present a new steganographic technique called random least
significant bits of pitch and Fourier magnitude steganography (RLPFS). It is based on hiding …

Information hiding based on bitrate switching is a novel steganographic scheme for voice
over IP, which can resist traditional steganalysis methods. However, the state-of-the-art …

This paper presents an improved version of a steganographic algorithm for IP telephony
called HideF0. It is based on approximating the F0 parameter, which is responsible for …
