(Internship) Integration of Privacy-Preserving Machine-Learning for Health Insurance Industry


SUMEX builds an innovative and market leading solution for Swiss medical invoice verification. Major accident and health insurers in Switzerland rely on SUMEX to detect mistakes and irregularities in medical invoices.


For our next-generation SUMEX Analytics Platform, we are going to offer machine learning (ML) services that are trained on the combined data of multiple insurers. This collaborative approach provides higher value than traditional ML models, which are trained on isolated data repositories.


However, the insurance market in Switzerland is competitive and subject to strict data protection regulations. Different insurers (data controllers) may be unable or unwilling to share data about their customers (data subjects). In a previous internship, various distributed and privacy-preserving Federated Learning (FL) frameworks were explored and a first concept for integration was written.

By operationalizing Federated Learning approaches in the SUMEX Analytics Platform, we aim to offer new ML services to Swiss insurers that:

  • Provide high business-value.
  • Encourage potentially competing data controllers to offer data access.
  • Protect the data of the data subjects from unauthorized access.

In this role

Challenges: This is a joint project of ELCA’s data science team and the SUMEX analytics team. You will closely collaborate with both. To be successful, you will need to learn about medical invoicing and understand the Analytics Platform’s architecture. You will work on a real-world problem and improve an important component of the SUMEX Analytics Platform to leverage FL solutions in a productive context.


What you will learn: You will take the role of a junior data scientist and help with the integration of a FL solution into the SUMEX Analytics Platform. To do so, you will explore the emerging field of privacy-preserving federated learning, as well as MLOps best practices and tools. You will evaluate different models and operationalize them in the SUMEX Analytics Platform.

  • Implement & Evaluate a ML Service based on existing FL technology.
  • Implement & Evaluate privacy preserving protocols.
