Storing and communicating secret and/or private information has become part of our daily
life whether it is for our employment or personal well-being. Therefore, secure storage and …

Data encryption aims to protect the confidentiality of data at storage, during transmission, or
while in processing. However, it is not always the optimum choice as attackers know the …

Image hiding aims to hide a secret image into a cover image in an imperceptible way, and
then recover the secret image perfectly at the receiver end. Capacity, invisibility and security …

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 …

Currently, the most successful approach to steganography in empirical objects, such as
digital media, is to embed the payload while minimizing a suitably defined distortion …

This study presents enhancing images authentication by securing watermarking hidden data
via shares generated from counting‐based secret sharing. The trustfulness of shares utilised …

Steganographic schemes are commonly designed in a way to preserve image statistics or
steganalytic features. Since most of the state-of-the-art steganalytic methods employ a …

We describe a novel general strategy for building steganography detectors for digital
images. The process starts with assembling a rich model of the noise component as a union …

This paper presents a new approach to defining additive steganographic distortion in the
spatial domain. The change in the output of directional high-pass filters after changing one …

Steganography is the art and a science of obscuring the presence of communication by
hiding content in electronic media and so obscuring the presence of communication from the …
