An Efficient Prediction-and-Shifting Embedding Technique for High Quality Reversible Data Hiding

open access: yesEURASIP Journal on Advances in Signal Processing, 2010
The embedding capacity of a histogram-based reversible data hiding technique is primarily determined by the peak height of the histogram. Recently, some studies have tried to embed data in the histogram of prediction errors by modifying the error values ...

Adaptive Reversible Data Hiding via Integer-to-Integer Subband Transform and Adaptive Generalized Difference Expansion Method [PDF]

open access: yes, 2014
We propose an adaptive reversible data hiding method with superior visual quality and capacity in which an adaptive generalized difference expansion (AGDE) method is applied to an integer-to-integer subband transform (I2I-ST).

A contrast-sensitive reversible visible image watermarking technique [PDF]

open access: yes, 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 ...

A New High Capacity Separable Reversible Data Hiding in Encrypted Images Based on Block Selection and Block-Level Encryption

open access: yesIEEE 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.
