Two Stage Reversible Data Hiding Based On Image Interpolation and Histogram Modification
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 4
Abstract
In this paper a two stage reversible data hiding technique is proposed. At the first stage, an interpolation technique is used to generate a cover image from the input image. The difference values from input image and cover image is used as the carrier to embed data. At the second stage, a histogram modification is applied on a difference image to embed data. The extraction process also works in two stages. The proposed algorithm is expected to increase the embedding capacity as two techniques are combined. The interpolation technique helps to keep the distortion low. Experimental results show that the new method has higher embedding capacity than other existing methods.
