This workshop introduced participants to the process of Data Protection Impact Assessment. This new tool of the GDPR is highly relevant for any processing of personal data, as it helps to structure the process, be aware of data protection issues and the relevant legislation and implement proper safeguards to protect data subjects. For processing operations posing a high risk for data subjects, a DPIA is mandatory from May 2018. The interactive workshop provided a framework for DPIA and guidance on specific questions such as when a high risk is likely to occur or how specific risks can be evaluated, which was assessed by participants in an interactive session with two different scenarios.
