设计并实现了一套基于混沌的数码防伪系统.基于混沌密码技术,分别提出一种生成防伪码和验证码的混沌密码加密算法,并采用"双标双码、双向验证"防伪工作机制,构建了一个能进行电话查询的混沌数码防伪系统,实现了防伪查询智能鉴别,系统测试表明该系统防伪效果好且方便实用,适合推广.
A chaotic digital anti-counterfeiting system is designed and implemented.At first,a new chaotic encryption algorithm to generate anti-counterfeiting code and identifying code is proposed on the basic of chaotic cryptography.Then an anti-counterfeiting mechanism of "two codes,two-way authentication" is adopted.And a digital anti-counterfeiting system inquired by telephone is constructed to realize intelligent identification.At last,the results of system testing show that the system is effective,convenient and practical to popularize.
