There will be an estimated 35 zettabytes (35× 1021) of digital records worldwide by
the year 2020. This effectively amounts to privacy management on an
ultra-large-scale. In this briefing, we discuss the privacy challenges posed by
such an ultralarge-scale ecosystem-we term this “Privacy in the Large”. We will
contrast existing approaches to privacy management, reflect on their strengths and
limitations in this regard and outline key software engineering research and
practice challenges to be addressed in the future.
