摘要
为了实现盲提取,提出了把图像的DFT域系数进行量化处理,将秘密数据隐藏在隐秘图像的DFT频域系数量化结果的奇偶特性上.通过一系列攻击实验表明,该算法具有稳定性和安全性,能抵抗滤波攻击和奇偶统计分析.
In order to realize blind extraction,the DFT coefficients is modified according to the quantify mode. The secret data is embedded in the parity of quantified value. By a serie of aggressive experiments,the results show that,this hiding method not only is high stable and safe, but also can defend filtering offensive and odd and even statistics analysis.
