A Reversible Data Hiding Scheme Based on Two Dimensional Difference-Histogram Modification to Embed Binary Data
In this paper, a reversible data hiding scheme based on two dimensional difference histogram modification is proposed. We adopted difference-pairmapping (DPM) strategy. A sequence of pairs of difference values is calculated by taking each pixel-pair and its surroundings. Then, a two-dimensional difference-histogram is produced by counting the frequency of the resulting difference pairs. Then, a...
متن کاملLossless data hiding based on histogram modification
Lossless data hiding is the technique of embedding data in an image and retrieval of the data with lossless reconstruction of original image. In this paper, we present a novel lossless data hiding scheme based on histogram modification. This technique is based on differences of adjacent pixels for embedding data and has more hiding capacity compared to existing methods. The number of message bi...
متن کاملA Framework to Reversible Data Hiding Using Histogram-Modification
A Novel method of Stegnography to achieve Reversible Data Hiding (RDH) is proposed using Histogram Modification (HM). In this paper the HM technique is revisited and a general framework to construct HM-based RDH is presented by simply designing the shifting and embedding functions on the cover image. The Secret Image is embedded inside the cover image using several steps of specific shifting of...

متن کاملReversible Data Hiding Based on Median Difference Histogram
This work proposes a reversible data hiding algorithm that is based on the median difference histogram. The method divides the cover image into non-overlapping identical blocks. In each block, the median pixel is selected to calculate absolute differences between the median pixel value and the values of the other pixels. Then, these differences are used to generate a histogram and the histogram...
