Secur-e-Health results: safely combining data for better healthcare
January 2026This article was originally published in Dutch on TNO.nl. For your convenience, we have translated it here.
As a partner in the Secur-e-Health consortium, we work together with UMC Utrecht and Zilveren Kruis, among others, on safely combining healthcare data. The results of the Dutch pilot have now been published — and they show that our approach works.
The problem
Healthcare data is fragmented across hospitals, insurers and clinics. Combining this data can improve treatments, but privacy legislation makes this difficult in practice. Traditional research methods are time-consuming and often lead to underrepresentation of minorities and women in datasets.
Our approach
In the Dutch pilot, we used Secure Multi-Party Computation (MPC) to refine the SMART2 cardiovascular risk model. UMC Utrecht and Zilveren Kruis combined their data through our platform — without the data ever leaving their own organisation. The result: more accurate risk predictions tailored to the local population. An independent penetration test confirmed the safety of the approach.
“Hospitals see that their patients differ from European averages, yet they still rely on traditional predictions that they doubt are locally applicable.”
— Jannick Dorresteijn, internist at UMC Utrecht
The PET Travel Guide
The consortium has also published the PET Travel Guide: a practical handbook for healthcare organisations looking to get started with Privacy Enhancing Technologies. Our CEO Martine van de Gaar is one of the authors. The guide describes the complete journey from research question to structural adoption and identifies six key roles — researcher, data manager, privacy officer, lawyer, IT administrator and security officer.
Proven in practice
The technology that Linksight delivers — combining data without sharing it — has once again been proven in practice. In 2022, we started the Secur-e-Health project. Now there are concrete results showing that privacy-preserving data analysis in healthcare is not only possible, but also delivers better outcomes.
