本文对数字指纹技术的应用及国内外的研究进展做了综述。首先简单介绍了数字指纹系统及其在版权保护 上的应用。然后分别介绍了传统的数字指纹技术，以及新型的基于多用户通信技术的指纹技术。指出了当前数字指纹技术存 在的不足，提出数字指纹技术今后的发展方向是以通信技术的角度作为切入点来研究对抗合谋攻击问题。

This paper gives a review on the application of digital fingerprint technology, and the domestic and international research work on this topic. Firstly, it briefly introduces a digital fingerprint system and its application in intelligence protection. And then it introduces the traditional digital fingerprinting technology and the new fingerprint technology based on multi user communication technology. It points out the shortcomings of current digital fingerprinting technology, and proposes that the development direction of digital fingerprint technology in the future is to research anti collusion attack using communication technology perspective as a starting point.
