文本数字水印技术研究

Research of Digital Watermarking for Text Document

随着计算机技术和网络技术的飞速发展,数字文本的传播、拷贝、分发更加容易,同时也面临着非法传播和随意篡改的问题。文本数字水印技术可以保护数字作品的版权,防止盗版和侵权行为。该文分析了基于格式文本的数字水印技术的算法和研究现状,并重点讨论了针对当今比较流行的PDF格式化文档的数字水印算法,最后探讨了今后研究的发展趋势。

With the rapid development of computer technology and Internet technology, it is easier to transmit ,copy text, and at the same time it faces the problem of transmitting illegally and tampered hostility, Digital watermarking can protect copyright of digital products and prohibit piracy, This paper analyses the algorithms and research actuality of basis of formatted text document, and discusses the watermarking algorithms with regard to PDF document prevalent in and distribute the digital based on text document the watermarking on the current. Finally it gives the further research directions,
