Steganography is communicating in a way which hides the existence of the information. The
cover media can be any general digital format, such as, text, image, audio, video, etc. By …

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 …

In this paper, we propose a reversible data hiding scheme using (5, 3) Hamming code. A
cover image is partitioned into blocks of five pixels. An adjusted (5, 3) Hamming code …

Data hiding, also known as information hiding, plays an important role in information security
for various purposes. Reversible data hiding is a technique that allows distortion-free …

Reversible data hiding is a data-hiding technique which has the ability to recover the
original version from stego-images after the secret information is extracted. In this paper, we …

Reversible data hiding methods can embed secret data into multimedia to prevent attacks
from hackers. Reversible data hiding methods based on multiple stego-images have been …

Reversible data hiding can restore the original image from the stego image without any
distortion after the embedded secret message is exactly extracted. In this paper, a novel …

Recently, Jana et al. proposed the partial reversible data hiding (PRDH) based on (7, 4)
Hamming code, which deals with three images: the original image (OI), the cover image (CI) …

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 …

Reversible data embedding is a very important issue, especially in dealing with sensitive
images such as military data and medical data. Based on the edge-directed prediction …
