Group Management System of RFID Passwords for Item Life Cycle

摘要

The data on RFID tags placed on items must be protected to secure the privacy of that information throughout the item life cycle from production to purchase to recycling. Therefore, we propose low cost RFID tags with an access control function of using a password and a system that assigns and manages a different password for each group of RFID tags. We also explain how using the system could protect consumer privacy, and how the RFID tag could be used throughout the entire life cycle of an item.
