The introduction of the General Data Protection Regulation (GDPR) came to further strengthen the need for transparency—one of its main principles—and with it, the users’ empowerment to make service providers more responsible and accountable for processing of personal data. The technological infrastructures are not yet prepared to fully support the principle, but changes are bound to be implemented in the very near future. In this work (1) we comprehensively elicit the requirements one needs to implement transparency as stated in GDPR, and (2) we verify which current Transparency Enhancing Tools (TETs) can fulfil them. We found that work still needs to be done to comply with the European Regulation. However, parts of some TETs can already solve some issues. Work efforts need to be put on the development of new solutions, but also on the improvement and testing of existing ones.
