Secure Multi-Party Computation

Privacy and data sharing

Different organizations see the added value of sharing data. It often provides efficiency, ensures that risks or threats can be better assessed or averted, or provides new insights to better serve customers. Data is therefore also called the new oil. At the same time, the question arises as to whether all those data sets can simply be combined. With the advent of the General Data Protection Regulation (GDPR), new restrictions are placed on which data can be shared for which purpose and in which way. However, data protection is about more than privacy and personal data. For example, companies also want to prevent commercially sensitive information from falling into the wrong hands.

Innovative solutions

There are innovative technical solutions to generate the functionality of a shared database without having to reveal the data. One of those solutions is Secure Multi-Party Computation (MPC). This 'toolbox' of cryptographic techniques makes it possible for multiple parties to collectively count on data as if they had a shared database. At the same time, they can never see each other's data with mathematical certainty. With this 'toolbox' organizations connect the most sensitive databases securely. This paves the way for all kinds of new products and services that were previously thought impossible. TNO is conducting research with multiple parties into MPC and its applications. In addition to MPC, other privacy enhancing techniques are also being investigated.

The workshop

We are happy that TNO gave permission to make this video registration from the interactive workshop in which they introduce MPC. Be there too short some other privacy-enhancing techniques mentioned (federated learning, differential privacy and bloom filters). Of course, the legal challenges that should be taken into account when using these techniques are also addressed.

The following components are covered:

  • MPC introduction
  • Interactive MPC demos
  • Presentation of MPC applications
