先前已经提出了具有扩频序列(SS)的数字水印技术。然而,在以前的研究中使用的SS序列不一定具有良好的相关性。前人的研究也提出了具有理想自相关和互相关特性的完全互补码(CCC),以及完全互补码的构造和扩展方法。然而,在研究中的一些方法不具有良好的自相关或互相关特性。本文利用最新的完全互补码构造器从水印图像中检测出嵌入的秘密信息。在实验结果中,我们成功地检测出秘密信息的水印对各种攻击。
Digital watermarking technologies with spread spectrum sequences (SS) have previously proposed. However, the SS sequences used in previous studies do not necessarily have good correlation properties. The previous studies also have proposed the complete complementary codes (CCC), which have an ideal auto-correlation and cross-correlation properties and methods for the construction and extension of the complete complementary codes. However, some methods in the studies do not have good auto-correlation or crosscorrelation properties. In this paper, we used the latest complete complementary code constructor to detect the embedded secret information from the watermarked images. In the experimental results, we successfully detected the secret information from the watermark against various attacks.
