基于逻辑签署技术的证件防伪系统

New anti-counterfeit system of identity documents based on logic signing technique

提出一种新型的基于逻辑签署技术的防伪机制,将它应用于证件的防伪系统中,对证件进行实时、离线验证。该防伪系统不依赖于数据库和网络的支持,通过证件的综合信息与验证信息之间的逻辑约束关系确保了证件在密码学意义上的高安全性,有效解决了证件的防篡改、防伪造和防盗用问题。

A new secure mechanism using logical signing technique was proposed to protect identity documents against forgery, tampering and illegal possession. And it is applied to the anti-counterfeit system of identity documents so as to make it verified real-time and off-line. It is an open system totally independent of databases and networks, and it is eryptographieally secure due to the close logical association between synthetie information and verification information of identity documents.
