Pixel value differencing (PVD) and least significant bit substitution (LSB) are two widely used
schemes in image steganography. These two methods do not consider different content in a …

This paper proposes two different implementations of a double-layer message security
scheme. In both schemes, the first layer is of a cryptographic nature, employing the AES …

Since the rise of the Internet, information security has been one of the most important factors
in networking. Cryptography and steganography are the arts and sciences of secret …

Background: The confidentiality of a message may at times be compromised.
Steganography can hide such a message in certain media. Steganographic media such as …

Steganography is a technique of concealing the message in multimedia data. Multimedia
data, such as videos are often compressed to reduce the storage for limited bandwidth. The …

We introduce the notion of an application-based covert channel—or ABCC—which provides
a formal syntax for describing covert channels that tunnel messages through existing …

In recent, the confidentiality of important data is indispensable for Internet users. Although
both the encryption and steganography schemes are well suited to protect the confidentiality …

The rapid growth of the internet and the internet of things (IoT) refers to the next phase of
information revolution whose context involves billions of smart devices and sensors …

The goal of steganography is to hide the data in another medium, meaning disguising the
data, so that the existence of the messages can be concealed. Steganography can be …

Data hiding or information hiding is a prominent class of information security that aims at
reliably conveying secret data embedded in a cover object over a covert channel. Digital …
