A reversible watermarking scheme is one of the improvement in a histogram shifting modulation modifies local precision of image content. In existing schemes hides a very less images and the capacity, distortion is more so that we propose dynamic histogram shifting insert higher images into a single original images and with the lesser distortion. For the same capacity, achieve the Peak Signal-to-noise ratio(PSNR) is more than 1to 4DB. Invariant image classification is to classify the parts of the images and embedder, extractor remain synchronize with the watermarked image. Classification of original images derives from image itself.
