Matrix barcode authentication scheme base on public Key cryptosystem

摘要

This paper presents an improved matrix barcode to verify authenticity of products. In this scheme, the server use Java to generate reliable and secure keypairs, use public key to encrypt product information, then use the cipher text to generated Qrcode barcode, customers use handset to decode Qrcode barcode, get cipher text and transfer to manufacturer, and then verified through GPRS networks. The scheme combines matrix Qrcode barcode and public key cryptography advantages, we show the framework of the scheme, and give the implementation key codes, can help manufacturer to verify the authenticity of products, also have a good industrial efficiency.
