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) …

Steganography is the science and art of covert communication. Conversely, steganalysis is
the study of uncovering the steganographic process. The evolution of steganography has …

Multiple image hiding aims to hide multiple secret images into a single cover image, and
then recover all secret images perfectly. Such high-capacity hiding may easily lead to …

This paper presents a literature review of image steganography techniques in the spatial
domain for last 5 years. The research community has already done lots of noteworthy …

In order to improve the robustness and capability of resisting image steganalysis, a novel
coverless image steganography algorithm based on discrete cosine transform and latent …

Video steganography is the art of unobtrusively concealing secret data in a cover video and
then recovering the secret data through a decoding protocol at the receiver end. Although …

This paper proposes a new adaptive least-significant-bit (LSB) steganographic method
using pixel-value differencing (PVD) that provides a larger embedding capacity and …

Most of the existing image steganographic approaches embed the secret information
imperceptibly into a cover image by slightly modifying its content. However, the modification …

Images have been repeatedly used as the perfect environment to hide information through
the use of steganography techniques. Whether messages, documents or even other images …

A novel local binary pattern‐based reversible data hiding (LBP‐RDH) technique has been
suggested to maintain a fair symmetry between the perceptual transparency and hiding …
