The Private Compute Core silos data away from the rest of the operating system to reduce the privacy risks associated with machine learning and user data. Some Android features currently handled in the Core include Live Caption — which uses speech recognition to caption any video — and Smart Reply, which suggests responses in messaging apps based on context. Without a silo, Google and other companies could potentially peer deeper into individuals’ lives.
Private Compute Services will allow machine learning to update without giving the Core direct access to the internet, Google said via its Security Blog. Specifically, it’s offering an open-source, intermediate framework with multiple privacy technologies, such as code to strip out personally identifiable information.
Google is promising to publish its source code so Services can be audited by outside parties, such as security researchers.

The company didn’t say when Private Computer Services will actually roll out. Android 12 is just days or weeks away from release, however, and it would make sense for the Core to have update mechanisms already in place.
