DCT-based Reversible Data Hiding Scheme
Journal of Software, 2009 To enhance the hiding capacity of Chang et al.’s reversible DCT-based data hiding scheme, in this paper we propose another method called a layer-1 data embedding strategy. Our proposed layer-1 strategy considers some areas not used by Chang et al.’s scheme, which we call layer-2 data embedding.

IEEE Access, 2019 Reversible data hiding in encrypted image (RDHEI) is a technology that can simultaneously implement privacy protection and reversible information hiding. For RDHEI, the main problem is the conflict between embedding capacity and real reversibility.

A contrast-sensitive reversible visible image watermarking technique [PDF]
, 2009 A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

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.
