Abstract :
A wavelet domain steganography algorithm based on redundancy evaluation, named as RES, is proposed for the JPEG2000 baseline system. The compatibility and reversibility is ensured by taking into account both the process of uniform quantization and rate-distortion optimized truncation. Every embedding point and its intensity is adjusted image adaptively to enlarge the information hiding volume. The experiment shows that the proposed method is feasible and effective
