电话数字防伪系统的设计与实现

为了防止假冒产品的蔓延，设计和开发了电话数字防伪系统。该系统为每一件产品产生惟一标识并存储在数据库中，用户通过电话在数据库中查询所购买产品的标识可以确定产品的真伪。系统采用了基于随机方式和混沌过程的标识产生算法，使得标识难于破译。在数据库设计上，采用了分表存储标识的方法，这样不仅便于数据库管理，而且还可以提高查询速度。该系统具有可靠性高、运行速度快和使用方便等特点。

Design and Realization of Telephone-number System for Anti-counterfeiting

In order to prevent counterfeit product from spreading, the telephone-number system for anti-counterfeiting is designed and realized. The system produces an exclusive label code for every product and stores in database. Users can confirm whether the products they purchased is counterfeit or not by querying the label codes of these products. The random method and chaotic sequence are adopted in the system for producing label codes in order that the label codes are difficult to be decrypted. The multi-tables are used in designing database. This leads to convenient database management and high query speed. The system is high reliable and used very conveniently and run fast.
