N2 - In this paper, a robust method for hidden information in the wavelet domain is presented. The proposed steganographic method uses the Wavelet domain iterative center weighted median (WDICWM) algorithm to estimate the noise areas of an RGB color image. The noise areas or pixels are proposed as places to hidden information to provide good invisibility and fine detail preservation of processed images. The proposed steganographic method consistently identifies if the wavelets coefficients of an image contains noise pixels or not, this algorithm works with variances and standard deviations of the same wavelet coefficients of image. The experimental results from a known technique are compared with the proposed method to demonstrate its performance in terms of objective and subjective sense.
