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.

Our members are affiliated with the Systems Group and the Applied Cryptography Group at ETH Zurich CS Department.
