To enhanced robustness and capacity as well as maintains of image transparency of the watermark,a novel watermarking technique combination bit plane is proposed.In this method,carrier image and fingerprint image are decomposed into bit planes after discrete multiwavelet transform(DMWT),respectively.By means of the ranked bit-stream of the image sub-band coefficients using the bit planes combination,the method may adaptively embed hidden fingerprint data into wavelet sub-band coefficients.Experimentation results shows that the algorithm achieves better tradeoff between invisibility and robustness in various Conditional compression.
