【摘要】 计算机网络的快速发展,使得数字内容比如音频、视频产品在网络上的传播变得更加容易,由此衍生出的版权保护问题受到了人们的广泛关注。如何在防止盗版的同时保护用户的隐私也是一个亟需解决的关键问题。本文重点研究了如何将数字指纹技术和叛逆者追踪技术应用到数字产品的版权保护中,主要取得了以下研究成果: (1) 系统地介绍了信息隐藏和数字指纹的研究背景、现状及进展,概述了信息隐藏技术的分类及其应用领域。 (2) 对数字指纹的概念进行了简要的阐述,列举了一些指纹的例子,总结和分析了数字指纹技术的研究成果,讨论了各种数字指纹方案的优缺点,并介绍了一个匿名数字指纹方案。 (3) 概述了叛逆者追踪技术的概念及分类,分析了现有的追踪方案的性能,并详细介绍了一个匿名的非对称公钥叛逆者追踪方案。 (4) 全面分析和总结了现有的匿名数字指纹方案,基于群签名设计了一个匿名的非对称数字指纹方案。更多还原

【Abstract】 The fast development of computer networks facilitates the distribution of digital contents such as music and video.How to protect the copyrights of digital contents and protect privacy is a big challenge and receives a lot of attention.This dissertation focuses on how to apply digital fingerprinting and traitor tracing to the copyright protection of digital contents and privacy protection.The main results are as follows:(1) An overview and introduction to information hiding and digital fingerprinting is provided,including their research history,recent studies and developments.A summary of the taxonomy and applications of information hiding is given.(2) A brief description of fingerprinting is presented,including its concepts and examples.An analysis of the existing digital fingerprinting schemes is given,and their advantages and drawbacks are discussed.A detailed description of an anonymous fingerprinting scheme is provided.(3) Introduce the concepts and taxonomy of traitor tracing.Analyze the existing traitor tracing schemes,and describe in detail an anonymous asymmetric public key traitor tracing scheme.(4) A summary and analysis of the existing anonymous fingerprinting schemes is given.Based on a group signature scheme, An anonymous fingerprinting scheme is proposed.更多还原
