Recently, context information of studies on ubiquitous networks have been conducted, and techniques for reducing the time of service and increasing accuracy of recommendation are also being studied. But it is difficult to quickly and appropriately provide a number of services, because only basic context information is stored. And Applications in context-aware computing environment will be connected wireless network and various devices. Reckless access of information resources can make trouble of system. So, access authority management is a very important issue of both information resourcess and adaptation to system through founding security policy of needed system. For this reason, we suggest D-PACs which stores location, time, and frequency information of often used services, and propose the model of automated context-aware access control using ontology that can more efficiently control resources through inference and judgment of context information.
