There is little doubt that Big Data is an increasingly important topic as more and more of our data is digitized. Large organizations were quick to realize the enormous potential of correlating vast amounts of data. As with many technology advances, there are issues to be addressed – including the significant potential for Big Data analysis to flaunt privacy rules and expose the analysts to liabilities. This paper considers the privacy issues relating to Big Data analysis and investigates how emerging attribute-based access control technology can assist in protecting against unauthorized access to personal data in a Big Data context.
