| 摘 要： | 提出了一种基于3D-DCT的彩色图像信息隐藏盲检测算法.本算法不但可以在512×
512的RGB彩色图像中嵌入多达2048字节的数据,而且实现了完全盲检测,即在信息检测时,该
算法不需要原始图像和任何附加信息.同时,采用3D-DCT和算法中的信息嵌入方式,能充分地
利用信息载体的容量,很好地平衡隐藏信息的不可见性和稳健性之间的矛盾.算法采用了纠错编
码技术和数据扰乱技术,以提高算法抵抗各类攻击的性能.实验证明,该算法所隐藏的信息在
StirMark的攻击下,对高达3×10-1～10-2的误比特率,仍具有很好的稳健性.

| Abstract: | An information hiding algorithm for color images is proposed. This algorithm not only can hide data as many as 2048 bytes, but also can implement blind detection of the hidden information without resorting to the original image or any other additional information. The algorithm can trade off the conflict of invisibility and robustness of the invisible watermark by adopting 3D-DCT and the embedding method in this paper. The proposed algorithm adopts error-correcting coding and data interleaving techniques to improve the performance of resisting diverse attacks. The experimental results show that the hidden watermark is robust, even when the bit error rate before correction can be 3×10-1～3×10-2 under many attacks in StirMark. |
