Providing Ontology-Based Access Control for Cloud Data by Exploiting Subsumption Property among Domains of Access Control

Auxilia Michael, Raja Kothandaraman, Kannan Kaliyan
2019 International Journal of Intelligent Engineering and Systems  
In this paper, Ontology-Based Access Control is proposed.  ...  The experimental results show that the number of rules to be stored in Policy Base is reduced and reasoning time is also considerably reduced because of applying subsumption property and hence access decision  ...  Policy Base includes the explicit access control rules defined by the system data owner through security administrates.  ...

Using OWL and SWRL to represent and reason with situation-based access control policies

Dizza Beimel, Mor Peleg
2011 Data & Knowledge Engineering  
Within the SitBAC knowledge framework, scenarios of data access are represented as formal Web Ontology language (OWL)-based Situation classes, formulating data-access rule classes.  ...  A set of data-access rule classes makes up the organization's data-access policy.  ...  These abstractions can be used to model data-access scenarios and thereby enable the modeling of data-access rules.  ...

Access control management for e-Healthcare in cloud environment

Lili Sun, Jianming Yong, Jeffrey Soar
2014 EAI Endorsed Transactions on Scalable Information Systems  
This paper addresses existing access control methods and presents a semantic based access control model which considers semantic relations among different entities in cloud computing environment.  ...  This work shows how the semantic web technology provides efficient solutions for the management of complex and distributed data in heterogeneous systems, and it can be used in the medical information systems  ...  Semantic web technologies are based knowledge bases. It aims to first annotate data via common ontology, then interlink data on the web and allow one to query this web of knowledge.  ...
