Data hiding in gray scale images using Integer Wavelet Transform

Abstract: This paper presents a novel data hiding using Integer Wavelet Transform (IWT) through lifting scheme that aims to achieve high quality of stego image. This method transforms a spatial domain cover image into a frequency domain cover image. It hides the secret message into detail coefficients (CH,CV,CD) of IWT by construct a binary image in any of selected bit in CH, CV, CD separately and compresses that bit by using arithmetic coding. This method is very simple and effective.
