Reversible Watermarking using Histogram Shifting and Pixel Differences with Inverse S-scan order and Local Prediction
Naseera P. A
The Reversible Watermarking enables the embedding of Watermarks in a host image without any loss of host content, which is proposed for image authentication that if the watermarked image is deemed authentic, it can revert in to the exact copy of the original image before the embedding occurred. This paper convey the improved histogram-based reversible watermarking scheme based pixel differences with local prediction.Before performing the embedding process flip the host image, For each pixel, calculate the difference between them. And take the difference value for finding peak value of the histogram and hide the watermark in the flipped images histogram peaks. This will perform high security in data hiding. The revers process is performed at the receiver.
