This is one of the one of the 2019 R&I Actions for H2020 Topic identifier: ICT-24-2018-2019, Next Generation Internet - An Open Internet Initiative.
According the call text, this RIA will cover the following scenario:
"addressing critical challenges related to increasing trust in the internet such as authentication, authorisation, traceability, privacy and confidentiality in personal and non-personal interactions. This topic will engineer federated and/or decentralised technologies for supporting internet-wide e-identities with various levels of identification, reputation and trust, to serve as a basis for new business models for verifying and valuating personal data. Proposers should pay attention to the following dimensions: scalability, ease of use, deployability, sustainability, standardisation and compatibility with the eIDAS framework"
This discussion area will help to identify the challenges arising within the scenario described above, as well as potential solutions to address these challenges, and to identify gaps that need to be filled by research and innovation projects within this topic area.
