The project goal is to develop a big-data analytics platform and tools for large-scale studies of data under special constraints, such as information that is privacy-sensitive, or that has a varying level of quality, associated provenance information, or signal-to-noise ratio. Ethical considerations are also considered when necessary. This will serve as a proof-of-concept for federating and analysing heterogeneous data from diverse sources, in particular for medical and biological research, using ideas and expertise coming from CERN and the broader high-energy physics community.
CERN is a living laboratory, with several thousand people coming to work at its main campuses every day. For operational purposes, CERN collects data related to health, safety, the environment, and other aspects of daily life at the lab. Creating a platform to collate and enable intelligent management and use of this data — while respecting privacy and other ethical and legal obligations — offers the potential to improve life at the lab. At the same time, such a platform provides an ideal testbed for exploring new data analytics technologies, algorithms and tools, including machine-learning (ML)/deep-learning (DL) methods, encryption schemes, or block-chain-based ledgers. It also provides a natural bridge to collaborate with other scientific research domains, such as medical research and biology.
This project is being carried out in the context of CERN's strategy for knowledge transfer to medical applications, led by CERN's Knowledge Transfer group.
In 2020, the project activities focused mainly on the investigation of privacy-preserving techniques for data analysis, particularly in cases where machine-learning or deep-learning models are used. A systematisation of the state-of-the-art was conducted looking at different methodologies, such as homomorphic encryption, secure multi-party computation and federated learning. The existing implementations and their capabilities were assessed against reference use cases, including the extraction of features from brain MRI scans and aggregated data classification for epidemiological research. In 2020, two new collaborators joined the initiative: the University of Madrid, Spain, and the Seoul National University Bundang Hospital (SNUBH), South Korea, sharing expertise in security and the analysis of medical data.
After our initial systematisation of knowledge related to privacy-preserving methods, we will begin work to develop one or more methods, integrating them into the ML/DL inference algorithms of the reference use cases. Extension to the full model training process will then be addressed.
In November 2020, CERN openlab entered into a collaboration with the OpenQKD project to assess the use of distribution infrastructures for the quantum keys used for secure analysis of data. The integration of QKD in the data analysis process will be investigated as an additional layer for protecting transactions.
