摘要
本文设计了一个基于可见水印的PPT课件版权保护系统,提供了课件格式转换、图片查看、水印嵌入、水印清除和网上发布等功能。该系统的设计充分考虑了PPT课件图片的特性,版权通告采用了自适应图像特性的可见水印技术,为能按需还原图像采用了基于直方图的可逆数据隐藏技术。
A PPT courceware copyright protection system based on visible watermarking is designed in this paper.This system includes courceware format conversion.image viewer, watermarking embedding,watermarking removal and Web publishing,An adaptive visible watermarking algorithm is used for copyright announcement by considering the characteristics of the original image, and to remove the embedded watermark,a data hiding algorithm based on the histogram is used.
