ID-based interoperation between digital and physical resources in ubiquitous environment

초록

The ubiquitous technology - mainly represented by RFID (Radio Frequency Identification) and USN (Ubiquitous Sensor Network) technology - has been attracting public attention in various fields of industry in the twenty-first century. In the meantime, people begin to think of real & ultimate ubiquitous services providing the convergent services interconnecting each area of the u-service systems. In order to connect various resources & services in u-environment, ID-system is so important in that resources including even creatures and plants will be given IDs and managed by ID-system for incorporations of u-services. In this idea, this paper introduces basic concept and various types of ID-system with some issues for interoperation among ID-systems. Then, main part of this paper proposes the method for enabling interoperation between two different types of ID-systems such as digital resource and physical resource ID-system in terms of 'identifiers' and ID management system'. New services generated by proposed method in this paper will be a potent catalyst to expand ubiquitous technology, considering that tangible and profitable itservices are still limited.
