隐形加密PDF417条码的药品防伪系统探析

Discussion on Drug Anti-counterfeit System Based on Invisibly Encrypted PDF417 Barcode

分析了目前常见药品防伪系统的不足,介绍了PDF417条码的基本原理。探讨了采用红外隐形油墨印刷的PDF417条码隐形方法和基于DES,ECC,RSA的三重条码加密方法,并设计了基于隐形加密PDF417条码的药品防伪系统,详细阐述了该防伪系统的工作原理、防伪系统结构设计和防伪系统软件设计,分析了系统的防伪能力。结果表明,该系统有较强的防伪能力,适合药品防伪,可有效杜绝假冒伪劣药品的泛滥,充分保护商家和消费者的权益。

The defects of common drug anti-counterfeit systems were analyzed and the basic principles of the PDF417 barcode were introduced. The invisible method of PDF417 by IR invisible ink printing and the encryption method of treble barcodes based on DES, ECC and RSA were discussed. A drug anti-counterfeit system based on invisibly en- crypted PDF417 barcode was designed. The working principles, structure design, and software design of the anti-coun- terfeit system was illustrated in details. The anti-counterfeit capability of the system was analyzed. The result indicated that this system is powerful enough in anti-counterfeit and proper for the anti-counterfeit of drugs. Besides, it can effec- tively put an .end to the spread of counterfeit drugs and fully protect the rights and interests of sellers and consumers.
