一种基于图像内容特征的自适应水印认证系统

An Adaptive Watermark Authentication System Based on Image Content Features

随着计算机网络和多媒体处理技术的快速发展,图像作品的处理、复制传播以及销售越来越便捷,但随之带来了潜在的安全隐患.数字水印技术是保证图像作品的真实性与完整性的一个重要手段,本文提出了一种自适应图像水印认证系统,系统提取图像内容特征作为水印信息,并利用人类视觉系统(HVS)特性,实现水印的自适应嵌入和盲检测功能.

With the rapid development of internet and multimedia processing technology, image process- ing, copy propagation and its selling become more and more convenient, but it also brings potential secu- rity hazards. It＇s known that digital watermarking technology is of vital importance to ensure the authen-
