【摘要】 数字产品的版权保护问题越来越受到人们的重视，而密码技术是解决这一问题的重要手段之一，本文中重点研究如何将现代密码学技术应用到数字产品的版权保护中，即数字指纹技术，以保证数字产品的出版发行能够按正常商业形式运作。研究成果如下：( 系统地介绍了信息隐藏与数字指纹的由来、研究进展和现状，概述了信息隐藏技术的应用与分类，阐述了密码学、信息隐藏与数字指纹间的关系。( 简要地介绍数字指纹概念及指纹的例子，解释了一些常用的相关术语，对现有的研究成果进行了全面总结，分析、讨论了各类数字指纹技术的优缺点。( 针对现有的匿名指纹方案进行分析与总结，设计了两种匿名指纹方案。( 分析了现有的追踪方案的各方面性能，设计了两种非对称的公钥叛逆者追踪方案。更多还原

【Abstract】 Copyright protection is taken into account by more and more people and cryptography is one of the important solutions to this problem. This dissertation focuses on how to apply the modern cryptography to the copyright protection of digital content, namely the digital fingerprinting technology, in order that the issue of digital content is run by natural commercial format. Following are the main result of this thesis:( Introduce the origin, evolvement and states of information hiding and digital fingerprinting technology, summarize the application and class of information hiding, expatiate the relation of the cryptography and information hiding and digital fingerprinting technology.( Introduce the conception and examples of the digital fingerprinting simply, explain the terms in common use, summarize the results of the research, analyze and discuss the strongpoint and shortcoming of all kinds of fingerprinting scheme. ( Analyze and summarize the existing anonymous fingerprinting scheme, design two anonymous fingerprinting scheme.( Analyze the performance of the existing traitors tracing scheme, design two asymmetric public-key traitors tracing scheme.更多还原
