Scalable privacy-preserving technologies for cross-border federated computation in Europe involving personal data

Using big data for digital services and scientific research brings about new opportunities and challenges. For example, machine learning methods process medical and behavioural data for finding causes and explanations for diseases or health risks. However, a large amount of this data is personal data. Leakage or abuse of this kind of data and potential privacy infringement (e.g. attribute disclosure or membership inference) risks are a cybersecurity threat to individuals, society and economy and an impediment for further developing data spaces involving personal data. Vice versa, adequate protection of this data according to the GDPR can also prevent its full utilization for society. Advanced privacy-preserving computation techniques such as homomorphic encryption, secure multiparty computation, and differential privacy are being researched and have proven promising to address these challenges. However, further research is required to ensure their applicability in real-world use case scenarios. For example, fully homomorphic encryption is not practically applicable in many cases and secure multi-party computation often imposes special infrastructural requirements.

Building on research and innovation in the area of privacy-preserving computation, proposals should address scalability and reliability of privacy-preserving technologies in realistic problem areas and take integration with existing infrastructures and traditional security measures (e.g. access control) into account. They should respond to users’ needs, e.g. for research and digital services in access and data management for citizens geared towards their own profiles (incl. dynamic personalised recommendations for improved cybersecurity) or in personalised medicine, taking into account the gender dimension where relevant. They should further address the legacy variation in personal data types and data models across different organisations in the same business sector and/or across different potential application sectors. A proposed solution should include validation or piloting of privacy-preserving computation in realistic federated data infrastructures and more specifically European data spaces involving personal data (e.g. the EU heath data space). It should be guided by the EU’s high standards concerning the right to privacy, protection of personal data, and the protection of fundamental rights in the digital age. It should ensure, by-design, compliance with data regulations and specifically the GDPR. Wherever possible, solutions should be developed as open source software.

Consortia should bring together interdisciplinary expertise and capacity covering the supply and the demand side, i.e. industry, service providers and end-users. Participation of SMEs is strongly encouraged. Legal expertise should also be incorporated to assess and ensure compliance of the technical project results with data regulations and the GDPR.
