摘要
根据对现有技术的分析,对数字水印算法的某些方面进行了改进,即将加密的二维图像作为水印嵌入到数字作品中。以人类的视觉模型为依据,进行嵌入算法的设计。实验结果表明,这种改进方法具有良好的鲁棒性和安全性。
The research focuses on digital watermarking in DCT-domain.An encrypted binary image is used as the watermark and then based on the features of human visual system(HVS)a new watermarking algorithm is proposed.The simulation has shown that better robustness and security can be resulted with the proposed system.
