本文首先介绍了基于扩频原理的数字水印生成技术,概述了在图像处理中被广为利用的小波变换。在对印技术理论分析基础上,提出了基于离散小波变换一维水印嵌入算法的一种实现方法,并给出实验仿真结果。

Abstract: This paper firstly introduces the digital watermark production technology based on
expanding frequency principle, also sums up to the small wave transformation in picture process on basis of analysis of watermark technology theory. What’s more, the paper suggests an experimental method---one dimension watermark inlayed calculation based on dispersed small wave transformation, at the same time gives out the experimental emulating result.
