An example for such a use case is machine learning on clinical data.

The need for data privacy and security -- enforced through increasingly strict data protection regulations -- renders the use of healthcare data for machine learning difficult.

To address this, we propose a secure 3-party computation framework, CECILIA, offering PP building blocks to enable complex operations privately.

In this setting, it can also be a problem to compute the global AUC, since the labels might also contain privacy-sensitive information.

We address this problem by introducing ESCAPED, which stands for Efficient SeCure And PrivatE Dot product framework, enabling the computation of the dot product of vectors from multiple sources on a third-party, which later trains kernel-based machine learning algorithms, while neither sacrificing privacy nor adding noise.

Eye tracking is handled as one of the key technologies for applications that assess and evaluate human attention, behavior, and biometrics, especially using gaze, pupillary, and blink behaviors.
