Data hiding is a security technique used to conceal secret information into digital media.
Reversible data hiding can guarantee that the secret message can be extracted correctly …

Image Steganography is one of the most well-known methods where a top-secret data is
embedded into the pixels of an image by altering some of its pixel values. Reversible Image …

Recently, Luo et al. proposed a new block-based reversible data hiding method that divides
an image into blocks, sorts all pixels within a block and then chooses the middle sorted pixel …

This paper introduces a new reversible data hiding algorithm in the encryption domain. It
integrates data hiding into the image encryption process to achieve different level of access …

In 2008 Lin et al. proposed a reversible steganographic method with a high payload for
JPEG images. Because modifying the quantized DCT coefficients may lead to serious image …

Recently, many researchers have proposed reversible data embedding schemes in which
payload can be added and extracted to digital multimedia. In this paper, we propose a …

Reversible data hiding can embed secret data into the cover image to cheat hackers,
thereby avoiding the interception attack. The previous methods modify non-embeddable …

The main goal of reversible data hiding algorithms is to embed the secret information in
cover image and recover it back successfully. So we have implemented two methods. In first …

Reversible data hiding is the technique that allows embedding (hide) data inside an image
and later the hidden data can be retrieved as required and the exact copy of the original …

Steganography means hiding the fact that communication is taking place, by hiding an
information in another information. Different applications have different requirements of the …
