Scalable Oblivious Data Analytics (SODA)

Advanced security solutions for big data analytics in healthcare

The Alexandra Institute’s Security Lab joins EU-funded research project to develop privacy-preserving techniques and prototypes for data analytics.

Big data analytics holds a huge potential for knowledge and value creation in society. But how can companies and organisations harvest the benefits of for example healthcare data, while at the same time protecting people’s privacy?

This topic has high priority at EU level. Therefore, the EU financially supports research projects on the development of privacy-preserving techniques that enable companies and organisations to perform data analytics on for example patient and healthcare data without compromising on security. 

The Alexandra Institute’s Security Lab and the Department of Computer Science at Aarhus University have received a total of DKK 9.4 million from the EUs' research and innovation programme Horizon 2020 for the research project SODA (Scalable Oblivious Data Analytics). The purpose of the project is to develop privacy-preserving techniques for big data analytics in the healthcare domain. The project is carried out in collaboration with Eindhoven University of Technology and the technology giant Philips Research – a world leader in healthcare technology. 

The SODA project investigates how to use sensitive data from multiple data assets without compromising on privacy. To achieve this, the project will optimise the performance and security of two techniques. 

Multi-Party Computation (MPC), which enables processing on encrypted data from multiple sources.

Differential Privacy, which is a method to obscure an individual’s identity and ensure that data remain anonymised at all times.

The objective is to be able to analyse data from multiple databases simultaneously without merging the databases. However, we need to improve the performance of existing technologies. To achieve this, the project will develop theory, build on existing software, and develop prototypes and applications based on the above techniques. 

The role of the Alexandra Institute is to implement software components, carry out user studies and build prototypes.

In the SODA project we collaborate with the technology giant Philips Research – a world-leading provider of innovative technology solutions for the healthcare sector. This includes for example scanners and measuring equipment that collect huge amounts of data in hospitals.

Philips is interested in adding an analytical service to their solutions – but without having access to data. In the future, this can be developed into a product that can help physicians and researchers determine if a therapy works, why it does not work, or how to improve it. But in order for that to happen, data needs to be secured.

User studies are an important part of the project. The project investigates how hospitals, doctors and researchers adopt new software and prototypes, and what patients feel about making their health data available provided that they are properly secured. We will therefore involve patients in different European countries in the project

Our project partners are:

The project is funded with 22.2 million DKK by the EU's research and innovation programme Horizon 2020. The Alexandra Institute and the Department of Computer Science at Aarhus University receive 9.4 million DKK of the total budget.

Take good care of your users' data!
