摘　　要：基于混沌密码技术,提出并完善了一种混沌密码数码防伪技术,以解决数码防伪技术长期面临的技术难题.研究一种混沌加密算法以生成商品防伪码和验证码,并提出一种支持多种查询方式多次查询验证的"双向验证"算法,形成并优化了"双标双码、双向验证"防伪工作机制;同时构建了一套既可现场识别又可通过电话、短信、网络(Internet、WAP)查询验证的全方位数码防伪系统,实现了防伪查询智能鉴别,以此证明所提数码防伪技术的有效性和可靠性.A novel chaotic digital anti-counterfeiting technology is proposed and improved based on chaotic cryptography, ordering to resolve the long-term technical problems. A new chaotic encryption algorithm is studied to generate commodity security codes and verification codes, and a new type of checking algorithm of ＂two-way authentication＂ is proposed which can provide many ways to search and multiple query verification, so as to form and optimize an anti-counterfeiting mechanism of ＂two codes, two-way authentication＂. Then a comprehensive digital anti-counterfeiting system is constructed to realize intelligent identification, which provides not only site identification but also checking by phone, short message and network （Internet or WAP）. It is proved that the proposed technology is effective and reliable.
