DC proposal: Knowledge based access control policy specification and enforcement

Abstract

The explosion of digital content and the heterogeneity of enterprise content sources have resulted in a pressing need for advanced tools and technologies, to support enterprise content search and analysis. Semantic technology and linked data may be the long term solution to this growing problem. Our research explores the application of access control to a knowledge discovery platform. In order to ensure integrated information is only accessible to authorised individuals, existing access control policies need to be associated with the data. Through in-depth analysis we aim to propose an access control model and enforcement framework which can be used to represent and enforce various access models both inside and outside the enterprise. Furthermore, through experimentation we plan to develop a methodology which can be used as a guideline for the lifting of distributed access control policies from the individual data sources to a linked data network. © 2011 Springer-Verlag.
