High capacity lossless data hiding based on histogram modification
This letter introduces a lossless reversible data hiding method. The original image is recovered without any distortion from the marked image following the extraction of the hidden data. The main algorithm is based on the relocation of zeros (or minima) and peaks of the histograms of the blocks of the original image to embed the data. It leads to the modification of the grey values of some pixe...
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 کاملHigh Capacity Data Hiding based on Predictor and Histogram Modification
In this paper, we propose a high capacity image hiding technology based on pixel prediction and the difference of modified histogram. This approach is used the pixel prediction and the difference of modified histogram to calculate the best embedding point. This approach can improve the predictive accuracy and increase the pixel difference to advance the hiding capacity. We also use the histogra...
متن کاملLossless Data Hiding Based on Histogram Modification of Difference Images
In this paper, we propose a new lossless data hiding method where distortion due to data embedding can be completely removed from the watermarked image after the watermark has been extracted. In the proposed method, we utilize characteristics of the difference image and modify pixel values slightly to embed the data. We show that the lower bound of the PSNR (peak-signal-to-noise-ratio) values f...
متن کاملA High Capacity Reversible Data Hiding Scheme Based on Multi-Level Integer DWT and Histogram Modification
A reversible data hiding scheme based on integer DWT and histogram modification is proposed. In the scheme, the cover media is firstly transformed by Integer DWT (Discrete Wavelet Transformation); then information is embedded through the modification of histograms of the middle and high frequency sub-bands of the DWT coefficients. In order to increase the embedding capacity, a multi-level schem...
