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.
