摘要
提出数据挖掘技术应用于多重数字水印的嵌入中,避免传统方法直接嵌入提取出的多重水印特征,而是将多重水印特征采用数据挖掘算法找到水印深层稳定特征,并将挖掘出的稳定特征嵌入到数字图像中,克服水印特征不稳定的影响,保证了数字图像多重数字水印嵌入的鲁棒性。仿真研究表明,这种方法能够有效克服不稳定水印特征的影响完成图像的多重数字水印嵌入,并具有较高的嵌入鲁棒性。
This paper put forward the data mining technology applied to multiple digital watermarking embedding.Avoid the traditional method direct embedded extracted multiple watermarks features,but will feature multiple watermarks with data mining algorithm to find the deep stable watermark features.And the stabilization of the dig into the digital image,overcome with characteristics of the influence of the stable watermark,ensure the digital image multiple digital watermarking embedding robustness.The simulation results show that this method can effectively overcome the influence of stable watermark features complete image multiple digital watermark,and has high embedded robustness.
