Toward the digitally named world with security and convenience using RFID tags

Recent years' advances in information technology and system LSI technology are spreading computing resources into ubiquitous places in the real world. In such an environment, 'What we should not do' is important as well as 'What we can do', since the problem in the computer science directly results in the problem in the real world. In this paper, we discuss the possibility and challenges in the 'Digitally Named World', which is the environment in which 'radio frequency ID's (RFIDs) are attached to any goods in the world, and any objects in the real world can be found by the readers of the RFIDs and the networked database system. Especially, we address the problem of security, privacy, total power consumption, and lifecycle management of the objects, and we propose the method for managing privacy about the relationship between objects and individuals.
