Privacy Preserving Systems Lab
We at the PPS Lab build, investigate, and research software systems for data privacy and data security. Our mission is to develop technologies that enable applications to safely and securely interact with users data while preserving individual's privacy and make it easy for developers to build and develop privacy preserving applications.

This award will foster a new collaboration with Google that aims to bring efficient and scheme-agnostic FHE support to the TensorFlow framework.
This grant aims at expanding our efforts to build an ecosystem for developing and deploying FHE applications.
Check the talk here and an extended version of the talk, ending with an interesting discussion on FHE tools development here.
This grant aims at expanding our efforts on end-to-end systems designs for data privacy.
Anwar Hithnawi got awarded the SNSF Ambizione grant to start the PPS Lab at ETH Zurich.
