TRUSTEE: Trust & Privacy Preserving Computing Platform For Cross-Border Federation Of Data

As we live in a data-driven era, the emergence of interdisciplinary, geographically dispersed, data repositories, is inevitable. The fact that these repositories do not necessarily abide with existing interdisciplinary data representation standards, nor do they necessarily belong to any data federation initiative, renders them unusable, since researchers cannot easily access this data. Moreover, most of the times, integrity, privacy, and security in such interactions is either very difficult, or impossible to maintain. Towards this end, TRUSTEE aims to bring a green, secure, trustworthy, and privacy-aware framework that will aggregate various interdisciplinary data repositories, such as Healthcare, Education, Energy, Space, Automotive, Cross-border etc. and also consider other European data federation spaces and trans-national initiatives, such as Gaia-X and EOSC. TRUSTEE will offer a secure-by-design framework, wherein stored data is homomorphically encrypted, thus offering researchers i) ability to search and use data in the encrypted domain, ii) a unified and meaningful FAIR representation of data, in an open and fair manner, iii) complex and context-aware queries through advanced ontologies, iv) data processing and analysis through transparent trustworthy ML workflows, over an intuitive AI playground, which will promote AI eXplainability, interoperability, and re-usability, by utilizing state of the art methods and paradigms, v) compliance with European privacy and ethical frameworks, e.g. GDPR, PIA, etc., vi) enforce privacy by applying a Homomorphic encryption layer, through which all data interaction will take place, vii) a blockchain-based transaction recorder to ensure accountability. TRUSTEE’s fully encrypted solution will be validated through six different use cases supporting GAIA-X, EOSC, EGI, etc. demonstrating a multi-disciplinary, Pan-European federated FAIR and private data ecosystem.

Our Role in the Project

In the context of TRUSTEE, K3Y will lead the implementation of the trustworthy and Explainable (XAI) solutions by investigating the security level of the AI models and explaining their decisions. K3Y will ultimately create a tool that will utilize and simplify the use of AI models. More specifically, it will be able to interpret and explain ML/DL models that are applied in homomorphically encrypted data. Moreover, K3Y will lead the market analysis activities of the TRUSTEE exploitable items and results. K3Y will contribute first to the identification of exploitable assets-results (EA/ER). Afterwards, K3Y will analyze the intellectual property rights (IPR) for each exploitable asset. K3Y will also identify the exploitable types and pathways and will map these paths per asset and partner. K3Y will proceed with asset analysis and value proposition using the business model canvas (BMC) and value proposition canvas (VPC). Lastly, K3Y will perform a SWOT and PESTEL analysis.
