KRAKEN Secure and privacy preserving platform (broKeRage And marKEt platform for persoNal data) aims to bring
personal data sharing and trading at a level of maturity that does not yet exist, by leveraging on:
i) the emerging paradigm of self-sovereign identity built upon a stack of distributed ledger technologies (multi-ledger) which
ensures future compatibility with different specific blockchain implementations for identity management. It will provide a
decentralized user-centric approach on personal data sharing and proving that it can incorporate the trust and security
assurance levels deriving claims from national identity schemas (eIDAS-compliant);
ii) tested data marketplace technologies which support data sharing as well as aggregated data sharing;
iii) A set of different data protection techniques based on advanced crypto tools (P/F/HE, FE, MPC, ABE…) coupled with
privacy preserving (AI/ML) analytics, featuring management of privacy / utility trade-offs and metadata privacy.
iv) The project will provide market-ready tools and services with industrial strength and suitable privacy metrics that will be
conveyed to data subjects with high usability.
Taking advantages of the emergent models and lessons learned from previous experiences, including existing and mature cloud-based personal data platforms CREDENTIAL and MHMD, as well as Streamr marketplace services, Kraken proposes an unprecedented approach, which creates an alternative to mainstream paradigms while fully granting the privacy and selfsovereignity of the data subject. KRAKEN enables advanced, convenient data sharing control relying on innovative end-to-end encryption and use of sophisticated proxy cryptography schemes grants data subjects with unprecedented control over their data. Furthermore, this ensures that even the cloud provider (data processor) cannot access the data in plain-text and hence protect access to personal data.
