Government (and private) entities are able to gather and analyze data from several disparate sources with ease. This ability to do large scale analytics of publicly accessible data leads to significant privacy concerns, especially when done by governments. The converse is also true, with concerns about data being shared by individuals and organizations to the web and the cloud. Our work develops a semantically rich, policy driven approach to address the privacy, security and usage concerns around such data.4 pagesen-USThis item is likely protected under Title 17 of the U.S. Copyright Law.
