Ontology Based Access Control: A Case Study through Ontology Based Data Access

Ontology Based Data Access (OBDA) is the provision of data access and integration as a result mapping that established between an ontology source. Thus, storing large amounts becomes easier, more powerful queries can be written, management complex information systems performed quickly effectively by using Semantic Web technologies. Control (OBAC) uses technologies to enable enforcement control mechanism. Therefore, only authorized persons protect privacy. In this study, OBDA OBAC are integrated improve security while providing virtualization with model-independent approach. use case study for healthcare domain presented. Hence, relational database hospital domain, Hospital related policy created. Also, relevant mappings Ontop framework finally, various executed SPARQL evaluate rules.
