摘要

With coding stream layered structure and progressive Transmission characteristics in JPEG2000, the paper presents a method research of the hiding fingerprint information. By means of the ranked bit-stream according to the fingerprint feature importance in space bit Planes, the method may adaptively embed hidden fingerprint data into wavelet coefficients from low to high frequency sub-band based on the coefficients redundancy. Experiment results shows, the algorithm achieves higher quality to the hided images, and better tradeoff between invisibility and robustness in various Conditional compression..
