A reversible data hiding method for encrypted images [PDF]
SPIE Proceedings, 2008 Since several years, the protection of multimedia data is becoming very important. The protection of this multimedia data can be done with encryption or data hiding algorithms. To decrease the transmission time, the data compression is necessary. Since few years, a new problem is trying to combine in a single step, compression, encryption and data ...

Exploring More Capacity for Grayscale-Invariance Reversible Data Hiding
IEEE Access, 2021 Grayscale-invariant reversible data hiding (RDH) in color images was developed recently in which the grayscales of the marked color image are required to be the same as that of the host color image.

A novel reversible data hiding based on adaptive block‐partition and payload‐allocation method
IET Image Processing, 2021 A reversible data hiding method based on partition is researched because it can effectively reduce shifting distortion in given embedding capacity. However, traditional partition is to divide an image into equal‐sized blocks, which cannot be divided ...

Efficient Reversible Data Hiding Simultaneously Exploiting Adjacent Pixels
IEEE Access, 2020 As an effective means to content authentication and privacy protection, reversible data hiding (RDH) permits us to hide a payload such as authentication data in a media file. The resulting marked content will not introduce noticeable artifacts.

A Novel Reversible Data Hiding Scheme Using Ripple Strategy and Histogram Shifting [PDF]
, 2014 [[abstract]]In this paper, we propose a reversible data hiding method based on pixel difference histogram shifting and ripple strategy. Because the local area has similar pixel value distribution in the natural image, the pixel differences will be ...
