With the rapid growth of multimedia technologies, many images are communicated over
public channels. Therefore, significant interest has been given to providing secure …

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

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 …

Image Steganography is a thriving research area of information security where secret data is
embedded in images to hide its existence while getting the minimum possible statistical …

Abstract Information hiding is an active area of research where secret information is
embedded in innocent-looking carriers such as images and videos for hiding its existence …

In steganography, secret data are invisible in cover media, such as text, audio, video and
image. Hence, attackers have no knowledge of the original message contained in the media …

Recently, unmanned aerial vehicles (UAV) technology has been utilized to monitor and
capture images from disasters to analyze, process, and take action in real‐time for a speedy …

This paper proposes an advanced scheme of message security in 3D cover images using
multiple layers of security. Cryptography using AES-256 is implemented in the first layer. In …

Abstract Conventional one-dimensional (1D) chaotic map have a simple structure, which is
easy to implement and has a low computational cost, but has a drawback that the range of …

Data hiding algorithms, which have many methods describing in the literature, are widely
used in information security. In data hiding applications, optimization techniques are utilized …
