Olha Drozd (WU Vienna) is in charge of a part of SPECIAL's research on user interfaces. Multi-level user interfaces, validated by user studies, give people access to the data that is collected about them, the purposes for that collection and the third parties who have access to the data. The multiple levels allow to get information either at a high level or very detailed, depending on the users' preferences and needs. Before consenting to give away personal data people can thus inform themselves about the consequences, without having to read long privacy policies. Later they can verify, with the same interface, what data has actually been collected and used, and they can change their consent accordingly.

The interface has multiple entry points. A user can select a functionality (a ‘purpose’) of the product/service they are interested in and see what data that functionality requires, then dig down deeper to see the actual data, and even deeper to see who is using that data, in case there are multiple parties involved. But the user can also start at a piece of data and see what functions it is used for, or look at the history of past interactions.

The poster & talk have the title Enabling Personal Data Processing Control via Dynamic Consent. and was created by Olha Drozd, Rigo Wenning (W3C) and Sabrina Kirrane (WU Vienna).

The OPERANDI workshop is part of the PET 2018 (Privacy Enhancing Technologies) Symposium, held in Barcelona, Spain, from 23 to 27 July 2018.

This project receives funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No. 731601
