Secure multi-party computation (MPC) is a promising solution in the digital advertising toolbox, allowing firms to protect data while continuing to offer existing services and innovating new ones. We will introduce some building blocks of MPC as well as basics of Ads measurement. Then we will present how MPC is being deployed at Meta to solve the private Ads measurement problem.
