Reversible Data Hiding for Video

2018
Difference expansion (DE) and histogram modification (HM) are efficient ways for reversible data hiding (RDH) into digital video. In most occasions, the reversibility of an algorithm cannot be confirmed until the data extracting experiments have been carried out, it means the design of a reversible data hiding algorithm lacks theoretical guidance.

Improved PVO-based reversible data hiding

Digital Signal Processing, 2014
This work extends a recently proposed reversible data hiding (RDH) scheme of Li et al. which is based on pixel-value-ordering and prediction-error expansion. In Li et al.?s method, the maximum and minimum of a pixel block are predicted and modified to embed data.

Reversible Data Hiding

2005
This paper presents a novel reversible data hiding algorithm, which can recover the original image without distortion from the marked image after the hidden data have been extracted. This algorithm utilizes the zero or the minimum point of the histogram and slightly modifies the pixel values to embed data.

Reversible Data Hiding in Shared Images With Separate Cover Image Reconstruction and Secret Extraction

IEEE Transactions on Cloud Computing
Reversible data hiding is widely utilized for secure communication and copyright protection. Recently, to improve embedding capacity and visual quality of stego-images, some Partial Reversible Data Hiding (PRDH) schemes are proposed.

Histogram-Based Reversible Data Hiding

2010
This paper presents a novel histogram-based reversible data hiding technique to embed secret data into gray-scale host image. This method utilizes the difference of the pixel values of the host image and the zero or the minimum points of the histogram of the difference image and modifies the pixel grayscale values slightly to embed secret data into ...
