The Technology of Digital Image Hiding Based on Discrete Wavelet Transform

On the basis of researching wavelet transform, we give a fast wavelet image hiding algorithm. Wavelet transform coefficient of the carrier image will fusion the information image's, Then using inverse wavelet transform gets the original image. In order to improve the performance of anti-attack of the hidden image, before hiding information image we do the scrambling operation. Experimental results show that the scrambling algorithm and hiding algorithm combines not only further enhance the security of the hidden system and robustness has also been enhanced.
