In this paper, authors propose a new reversible data hiding scheme that has two passes. In
first pass, the cover image is divided into non-overlapping blocks of 2× 2 pixels. The secret …

Digital image steganography algorithms usually suffer from a lossy restoration of the cover
content after extraction of a secret message. When a cover object and confidential …

This paper proposed an innovative approach for reversible data hiding (RDH) within images
in such a way that the image can be accurately recovered after extracting the data. The work …

A new irreversible data hiding spatial domain method, A 2 MLSB, adaptive to pixel value
(PV) and pixel value difference (PVD) using variable threshold on PV and PVD ranges, and …

The data hiding technique is used to hide a secret message into a cover image which is then
sent to a receiver without raising any suspicions. With a reversible (lossless) data hiding …

This paper proposes a novel reversible data-hiding scheme utilizing two steganographic
images. The proposed method is able to hide more secret messages than other messages …

After the extraction of hidden data, reversible data hiding (RDH) algorithms are able to
completely recover the original image without any error. For the past few years, a number of …

In reversible compressed image data hiding, the exact cover image is restored at
approximate efficient rate after extracting the secret data from the stego-image. The …

There have been discussed various data hiding methods which can embed the secret data
in an image. However, the image gets destroyed after extraction of the secret data at the …

Data hiding techniques are very significant in the research area of information security. In
this article, the authors propose a new reversible data hiding (RDH) scheme using …
