Getting to data nirvana – a user’s guide to data lakes and GDPR

A data lake is an infrastructure that permits different data sets from within a group to be combined and analysed together.

To analyse a data lake under GDPR, it is helpful to think of a data lake in two phases, which we analyse in our user guide.

The infrastructure phase

Here, the guide covers:

  • Identify the entity that is hosting the data lake.
  • Implement an intragroup data processing agreement.
  • Check data localisation rules.
  • Data protection impact assessment.
  • Data lake governance committee.

The applications phase

Specifically, we look at:

  • Data lake service provider becomes data controller.
  • Instructions from each affiliate as (original) data controller.
  • Mapping value transfers from data lake applications.
  • Data lakes and applicable law.
  • Anonymisation.
  • Additional purposes that are “compatible”.
  • Data protection impact assessments.
