Research on Privacy Protection in Express Information Management System

Due to use plaintext in express paper, the disclosure risk of user's privacy information widely exists in various express business processes. The paper analysis of the privacy information disclosure channels and reasons, research on the privacy protection method based on DES and RSA encryption and decryption technology. At the same time, this paper improvs the express acquiring process and delivery process to adapt to the implementation of privacy protection algorithm.In the express acquiring process, the system encrypts part of key privacy information then generates a two-dimensional code.Then the courier print and paste the electrical waybill which is used instead of partial key words. After transportation,delivery staffs use the mobile client to scan two-dimensional code on the waybill, and system will auto-decrypt the message then showing on the screen. By using these methods, it will reduces the risk of leaking effectively.
