| 摘 要： | 该文提出一种针对JPEG图像的隐藏算法,通过修改非0的DCT系数,使得要嵌入秘密信息位的奇偶性和非0的DCT系数与其对应的位置的差值的奇偶性相同,从而实现嵌入的目的.实验结果表明,该文提出的算法比经典的LSB算法有较好的隐藏容量,且隐秘图像有更好的视觉效果,且能够抵抗RS攻击.

| Abstract: | This paper presents a hiding algorithm for JPEG images,By modifying the non-zero DCT coefficients,makes the to embed hidden information bits and the difference between the non-zero DCT coefficients and its corresponding position of the same parity,to achieve the purpose of the embedded.The experimental results show that the proposed algorithm is better than the classic LSB algorithm in hidden capacity,and the secretimage has better visual effect,and be able to resist RS attack. |
