A study of information services based on personal belongings

In this paper we will discuss a general idea about an information system which provides information a user really needs in various situations, at home, at train station, and/or at office, etc. We will discuss how RFID could be applied for this kind of system especially from the standpoint of using RFID as a way to collect information of personal belongings. Also we will discuss security issues of using RFID as a component of the proposed system because while RFID could provide usefulness, it could also be very dangerous for revealing private information without user's awareness. Some solutions to this issue will be shown by introducing an additional tag to be attached to the original RFID.
