Steganalysis and steganography are the two different sides of the same coin.
Steganography tries to hide messages in plain sight while steganalysis tries to detect their …

Steganography is the primary method by which individuals can communicate covertly;
cryptography, on the other hand, fails at this, as it is possible to detect (the presence 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, the art of hiding of information in apparently innocuous objects or images, is
a field with a rich heritage, and an area of rapid current development. This clear, self …

This letter proposes a modification to the least-significant-bit (LSB) matching, a
steganographic method for embedding message bits into a still image. In the LSB matching …

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 …

Cryptology is the practice of hiding digital information by means of various obfuscatory and
steganographic techniques. The application of said techniques facilitates message …

Owing to the inefficiency to hide large volume of secret data for the reversible data hiding
(RDH) image steganography approaches, we propose two improved RDH based …

We consider methods for answering reliably the question of whether an image contains
hidden data; the focus is on grayscale bitmap images and simple LSB steganography. Using …

Since the inception of pixel value differencing (PVD) image steganography, it has drawn
considerable interest among the researchers of this field. However, most of the PVD based …
