清真牛羊肉溯源系统中 QR Code 二维码的应用研究

建立清真牛羊肉溯源系统可以对肉品生产运销过程中的危害物及穆斯林禁忌物进行有效控制，提高肉品质量安全。首先阐述了QRCode二维码的基本特性，设计了清真牛羊肉溯源系统的总体框架，实现了溯源系统QR码的生成，并利用DES算法对QR码进行加密，最后完成了QR码识别和溯源查询功能。建立基于QR码的清真肉品溯源系统，一方面保障了消费者对产品的知情权，另一方面提高了内品的安全性与可靠性。

Applied Research of QR Code in the Halal Beef and Mutton Traceability System

Establishing the traceability system of halal beef and mutton not only can control the hazards and Muslim taboo in the meat production marketing process, but also improve the security of meat quality. Firstly, the basic characteristics of the QR Code were elaborated and the framework of halal beef and mutton traceability system was designed. Then, the QR Code generation of traceability system was implemented, and using the DES algorithm, the QR code encryption and decryption were achieved. Lastly, the QR Code recognition and query function of traceability system were completed. This traceability system based on QR code, on the one hand, ensure the consumers right to know the products, on the other hand, improve the security and reliability of meat
