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 …

Information hiding refers to the process of inserting information into a host to serve specific
purpose (s). In this paper, information hiding methods in the H. 264/AVC compressed video …

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 this paper, a reversible image hiding scheme based on histogram shifting for medical
images is proposed. As we know, the histogram-based reversible data hiding is limited by …

Image steganography is a covert communication method that uses an image as the cover to
hide the truth from potential attackers that some secret message hidden in the image is …

The main objective in develo** a robust image watermarking technique is to obtain the
highest possible robustness without losing the transparency. To achieve this objective, this …

In this paper, we present a novel, reversible steganographic method, which can reconstruct
an original image effectively after extracting the embedded secret data. The proposed …

In this paper, we propose a novel interpolation and a new reversible data hiding scheme for
upscaling the original image and hiding secret data into the upscaled/interpolated image …

Most of the proposed methods of reversible data hiding based on difference expansion
require location maps to recover cover images. Although the location map can be …

In this paper, a novel optimal watermarking scheme based on singular-value decomposition
(SVD) using genetic algorithm (GA) is presented. The singular values (SVs) of the host …
