Private Compute Services helps improve features inside Android’s Private Compute core - like Live Caption, Now Playing, and Smart Reply.
Android prevents any feature inside the Private Compute Core from having direct access to the network; but machine learning features often improve by updating models. Private Compute Services helps features get these updates over a private path. Features communicate over open-source APIs to Private Compute Services, which removes identifying information and uses a set of privacy technologies, including federated learning, federated analytics, and private information retrieval, to preserve privacy.
