Reversible Data Hiding Through Histogram Shifting With A General Framework
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 engrafted functions on the front image. The hidden Image is inside the front
image using several steps of specific shifting of pixels with an order. The hidden image or logo is retrieved without any loss
in data on the cover and as well as in the hidden image. The Experimental results show the better Peak Signal to Noise Ratio
(PSNR) with the existing methods.
