Abstract: The digital anti-counterfeiting is a new high-tech anti-counterfeiting that synthesizes to make use of digital coding, encryption, database, computer network, correspondence and interactive voice response (IRV) technology. This article firstly analyses the security of digital anti-counterfeiting, designs a new digital anti-counterfeiting system, and enumerates two application examples of the system.

Key words: Anti-counterfeiting; Digital anti-counterfeiting; Digital cipher lock

摘要： 数码防伪是一种综合利用先进的数字编码、加密、数据库、计算机网络、交互式语音处理(IRV)等技术的新型高科技防伪技术，是当前国内最为流行的防伪技术之一。文章首先分析、借鉴了当前几种主要的数码防伪技术及其安全性；在此基础上进行创新，提出了一种新型的数码防伪系统；另外，还列举了两个应用实例进行检验。
