The European General Data Protection Regulation (GDPR) gives primacy to purpose: Data may be collected and stored only when (i) end-users have consented, often explicitly, to the purposes for which that data is collected, and (ii) the collected data is actually necessary for achieving these purposes. This development in data protection regulations begets the question: how do we audit a computer system's adherence to a purpose?
We propose an approach that identies a purpose with a business process,
and show how formal models of interprocess communication can be used
to audit or even derive privacy policies. Based on this insight, we propose
a methodology for auditing GDPR compliance. Moreover, we show how
given a simple interprocess data ow model, aspects of GDPR compliance
can be determined algorithmically.
