Reversible Data Hiding Based on Histogram by Using Gradient Adjacent Prediction
نویسنده
چکیده
In this paper, we use gradient adjacent prediction to present a new data hiding method based on histogram. Our method can increase the amount of hidden data, and keep higher PSNR of stego-image. According to experiment results, our method increases the amount of hidden data by 12.5% on the average as compared with Jang et al.’s method.

A Novel Reversible Data Hiding Based on the Prediction Error Image
Reversible data hiding has drawn a lot of interest recently. Being reversible, the original image can be completely restored without distortion. In this paper, a novel reversible data hiding scheme is proposed, which is based on histogram shifting of prediction errors. The JPEGLS prediction method is employed. We apply the peak point of a histogram in a prediction error (PE) image to generate a...
متن کاملHierarchical reversible data hiding based on statistical information: Preventing embedding unbalance
For reversible data hiding, the histogram-based difference expansion (DE) is one family of the generic methods where secret bits are embedded into an image by DE on prediction error. However, the ratio of the count of bit 0 to that of bit 1, embedded into the pixels with the same prediction error, will vary with the image and the secret bits, which leads to the embedding unbalance and image dis...

Recently, progressive interest is paid to reversible data hiding (RDH) in encrypted images, since it preserves the original cover can be recovered without any loss after embedded data is extracted to protect the confidentiality of image content’s.Earlier method used“vacate room after Encryption” in which data can be embedded by reversibly vacating room from the encrypted images. This might caus...
متن کاملReversible image hiding scheme using predictive coding and histogram shifting
In this paper, a reversible image hiding scheme based on histogram shifting for medical images is proposed. As we know, the histogram-based reversible data hiding is limited by the hiding capacity, which is influenced by the overhead of position information that has to be embedded in the host image. To solve this problem, the similarity of neighboring pixels in the images was explored by using ...
متن کاملReversible data hiding based on histogram modification of difference images by s-type and Hilbert curve scanning
Reversible data hiding technology has currently attracted great attention recently. Using reversible data hiding methods, original cover images can be recovered losslessly from the cover image embedded information. In this paper, spatial reversible data hiding schemes based on histogram modification of difference images are discussed, in which the pixel gray values of difference image are alter...
