To recover the original image losslessly, reversible wavelet transform should be used. Hence we employ the

integer wavelet transformation which maps integer to integer and can reconstruct the original signal without

any distortion. Although various wavelet families can be applied to our reversible embedding scheme, through

experimental comparison we have discovered that CDF(2,2) is better than other wavelet families in terms of

embedding capacity and visual quality of embedded images. In addition, it is noted that CDF(2,2) format h as
