| 摘 要： | 隐写术是信息隐藏一个重要的研究分支。论文给出一种新的基于DCT域的可以实现“大容量”、“盲提取”的隐写术算法,经过少许的变动,算法可以成为一种能够涵盖空域、变换域大部分替换类算法的“统一模型”。算法的描述基于DCT域,但其思想可适用于其它变换域。实验结果表明:在满足“不可见”、“盲提取”的前提下,算法能正确嵌入/提取“大容量”的秘密信息。

| Abstract: | Steganography is a important field of information hiding.This paper proposes a new algorithm based on DCT domain,which has high capacity of data hiding,and is blind extracting.By changing a little,This algorithm can become a generalization model which can cover most of the "algorithms of substitution".This algorithm is based on DCT domain,but its thinking can be applied to other transfer domains.The experimental results demonstrate this algorithm can correctly embed and extract high capacity of secret data. |
