One of the main pillars of the digitalization and the European Digital Single Market is the development of the European Data Economy. The volume of data, industrial and personal data, is growing rapidly in the EU and worldwide and the value of the data economy will continue to grow in the coming years creating new opportunities, products, services and jobs. Europe aims to lead this new sector of the economy and has designed a European strategy for data, setting-up the framework conditions that will enable the development of the European Data Economy based on European values, and on the safeguard of citizens rights in the digital world. The strategy addresses the following aspects: (1) legislation on data governance, (2) data availability, public dataset for reuse, (3) development of data sharing tools and data processing infrastructures, and (4) secure and competitive cloud-based data processing services.
KRAKEN (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, answering to the overall strategy of the European Data Economy, fostered by the European Commission, by leveraging on:
(1) 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);
(2) Tested data marketplace technologies which support data sharing as well as aggregated data sharing;
(3) 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.
The project provides market-ready tools and services with industrial strength and suitable privacy metrics that convey to data subjects with high usability.
Taking advantages of the emergent models and lessons learned from previous experiences, Kraken proposes an unprecedented approach, which creates an alternative to mainstream paradigms while fully granting the privacy and self-sovereignty 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.
