数字指纹的编码技术研究

摘要

Encoding technology for digital fingerprint has significant influence to digital fingerprinting system, which is a critical factor whether ownership can track the pirates and a most important component of digital fingerprinting system. During the development of fingerprinting technology, a number of typical fingerprinting encoding schemes have been proposed. Aim at some typical encoding schemes, we conclude these research results, and discuss their design idea and specific implementation. At last we present a summary and prospect on this topic.%　　指纹编码技术对数字指纹系统起着非常重要的作用，是发行商能否正确跟踪盗版用户的关键因素，也是数字指纹系统最重要的组成部分。在指纹技术的发展过程中，出现了一些比较典型的编码方案。针对几种典型的指纹编码方案，对这些研究成果进行归纳，讨论了指纹编码技术的设计思想及其具体实现，最后进行了总结和展望。
