The use of image communication has increased in recent years. In this approach, the encryption process is pe!formed by hiding the processing steps cf the wavelet transform. The attacker· cannot obtain the original image unless processing steps arc known. In this paper, the performance" of three different hidden wavelet-based schemes ace applied. First, hiding filter type« encryption scheme (HIT), second, hiding wavelet packet tree encryption scheme (HWP1), lastly, by combining the previous two methods (HFTWP1). Several experiments are given to illustrative the performance of the proposed schemes.
