As ubiquitous computing environment is expanding into our real society and the majority of IT technologies are focusing on ubiquitousness, the procedure for identifying an entity is getting more significan't in the future security system. However, users should be authenticated by every security application since they are heterogeneous and not collaborative each other. So in this paper, we propose a new authentication mechanism for guaranteeing ubiquitousness and usability with intelligent collaborations among authentication applications and surveillance systems for inter-space intelligent security applications.
