A reversible data hiding scheme based on integer-tointeger wavelet transform is proposed
in this paper. The scheme uses a Sudoku-based method to embed data by modifying the …

This paper proposes a novel reversible data hiding scheme based on the histogram-shifting-
imitated approach. Instead of utilizing the peak point of an image histogram, the proposed …

Secret information protection has received increasing attention from the information
technology community. Proposing a novel information hiding scheme to effectively conceal …

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 joint photographic experts group (JPEG) is the most popular format of digital image. In
this paper, a novel reversible data hiding scheme based on JPEG image is proposed. In …

Reversible image data hiding technology can not only ensure that the receiver can extract
the hidden data like the traditional data hiding technology, but also restore all the pixel …

Communication by transferring data using computer networks have an important role
nowadays. There are many activities which require sending or receiving data from one host …

This paper presents a lossless data hiding scheme. The proposed scheme is based on the
pixel difference histogram shifting to spare space for data hiding. Pixel differences are …

When JPEG images are used as cover objects for data hiding, many existing techniques
require the images to be fully or partially decompressed before embedding. This makes …

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 …
