Androids Private Compute Services is a suite of services that provide a privacy-preserving bridge between the Private Compute Core and the cloud. The Private Compute Core is a secure environment that is isolated from the rest of the operating system and apps where close-source features can safely operate. It is a secure partition for processing sensitive user data on-device, similar to ones used for passwords and biometric data. The Private Compute Core is where features like Live Caption, Now Playing, and Smart Reply operate in a network isolated manner from the rest of Android and apps. Private Compute Services provides a privacy-preserving bridge between the Private Compute Core and the cloud, making it possible for Google to deliver updated AI models and other updates to sandboxed machine learning features over a secure path. Communication between sandboxed features and Private Compute Services happens over open-source APIs that are included in the Android Open Source Project and can be controlled by publicly available surfaces like Android framework APIs. Private Compute Services helps the Android OS continue to innovate in machine learning while also ensuring user privacy.
