中文摘要：

针对不法快递人员将快递单信息用以市场交易,甚至根据快递单信息跟踪、骚扰收件人、发件人的违法行为,提出并实现了基于二维码技术的个人信息隐私保护物流系统（LIPPS）。采用分段加密技术对物流信息进行分层加密后转储到二维码进行二次封装,并设计不同等级授权机制解密相应信息完成物流业务操作。系统通过分层加密方案和权限分级设计解决了物流信息加密与物流业务流程的矛盾,实现了物流个人信息隐私保护,其方法可推广应用到其他需要分段封装的领域。

英文摘要：

Personal privacy was an important issue in logistics transit since plaintext information contained in the express list, even leading to criminal cases because of the recipient and sender privacy disclosure. This paper proposed a method, named logistics information privacy protection system based on encrypted QR code（LIPPS）. It used segment encryption method to en- crypt personal information and store ciphertext in the QR code, and designed authorization mechanism of different levels to de- crypt the corresponding information to complete the logistics business operations. This system can solve the contradiction be- tween information encryption and logistics business process by segment encryption design, and the solution can also be exten- ded to other segment encryption areas.
