An Information Hiding Algorithm for Color Images Using the Luminance Component

提出了一种利用亮度分量的彩色图像信息隐藏算法．本算法实现了隐藏信息的盲检测，并在５１２× ５１２的 ＲＧＢ彩色图像中嵌入多达 ２０４８字节的数据．算法有效地利用了数字通信理论中的前向纠错编码技术和数据扰乱技术，使水印抵抗各类攻击的性能得到了有效地提高．实验证明该算法能较好地平衡隐形水印的不可见性和稳健性之间的矛盾，所隐藏的数宇水印在ＳｔｉｒＭａｒｋ的攻击下，具有较好的抵抗能力．

An information hiding algorithm for color images using the luminance component is proposed. This algo-rithm not only can hide data as many as 2048 bytes, but also can implement blind extraction of the hidden informa-tion without resorting to the original image and any side information. The proposed algorithm adopts error- correcting coding and data interleaving techniques to improve the performance of resisting diverse attacks. The algorithm trades off the conflict of invisibility and robustness of the invisible watermark well. The experimental results show that the hidden watermark is robust to most attacks in StirMark.
