The role of personal data gained significance across all business domains in past decades. Despite strict legal restrictions that processing personal data is subject to, users tend to respond to the extensive collection of data by service providers with distrust. Legal battles between data subjects and processors emphasized the need of adaptations by the current law to face today’s challenges. The European Union has taken action by introducing the General Data Protection Regulation (GDPR), which was adopted in April 2016 and will inure in May 2018. The GDPR extends existing data privacy rights of EU citizens and simultaneously puts pressure on controllers and processors by defining high penalties in case of non-compliance. Uncertainties remain to which extent controllers and processors need to adjust their existing technologies in order to conform to the new law. This work designs, implements, and evaluates a privacy dashboard for data subjects intending to enable and ease the execution of data privacy rights granted by the GDPR.
