Unified Architecture for Managing User Profiles

Most of ubiquitous applications use proprietary information source to make user’s profile. And these information sources are not inter-operable with other applications. We developed the unified architecture for managing user’s profiles which can provides integrated access to the various information source as a form of user’s profiles and provides unified method to obtain user’s profile for the application. Using proposed architecture, ubiquitous applications can be developed more easily, and newly developed service or sensor can be integrated into existing applications quickly.
