摘要
针对JPEG2000基本压缩编码系统,提出了一种基于量化指标调制的信息隐写算法。该算法可以有效保持离散小波系数的直方图特性,抵御图像隐写直方图攻击。实验证明了算法的可行性和有效性。
An information steganographic algorithm is proposed based on QIM for JPEG2000 compression coding system. The algorithm can effectively maintain the discrete wavelet coefficients histogram features, and withstand stego-image histogram attack. Experiment proves the feasibility and effectiveness of the algorithm.
