433Secure Cloud Query Processing for Semantic Web-Based Social Media
treats these objects as subjects as long as these objects are URIs. This will allow agents possessing
model level access to generate models on a given subject.
Our current work also examines secure query processing in hybrid clouds (Khadilkar et al., 2012;
Oktay et al., 2012), and we will apply them for social media systems in the cloud. In the future, we
will explore various types of access control models for social media query processing and evalu-
ate them. This will give us a better idea of the most suitable access control models for cloud-based
social media query processing.
