摘要
数字水印作为一种防护技术,在数字产品的保护认证方面越发显得重要,成为当前计算机领域研究的热点问题之一。提出了一种在空域采用分块重复嵌入水印信息和HVS相结合的水印技术。实验结果说明,分块技术在空域的使用提高了水印的嵌入强度和降低计算复杂度,该算法在抵抗旋转、裁剪、缩放方面等有较强能力;水印算法与HVS技术的有效性相结合,数字水印具有很好的掩蔽性。
As a technology of protection, digital watermarking is becoming more and more important in copyritht and protection of digital products. Digital watermarking is one of hotspot of time. This issue presents a block watermarking algorithm in pace domain base on HVS. Experiments show that this algorithm can increase intensity of watermarking and reduce complexity of calculation. The algorithm of space domain owns better abilities to against outer attacks such as rotation, cutting and distortion. Integrating HVS technology and the digital watermarking, the digital watermarking has invisibility.
