Users are able to use the information and service more free than previous wire network due to development of wireless network and device. For this reason, various studies on ubiquitous computing have been conducted. Also, applications in ubiquitous computing environment will be connected wireless network and various devices. According to, recklessness access of information resource can make trouble of system. So, access authority management is very important issue both information resource and adapt to system through founding security policy of needed system. But, existing security model is easy of approach to resource through simply user ID and password. For this reason, we suggest D-PACs(Dimension Profile and Access Control system), which stores location, time, and frequency information of often used services, and propose model of automated context-aware access control using ontology that can more efficiently control about resource through inference and judgment of context information that collect user's information and user's environment context information in order to ontology modeling.
