What is Android 12 Private Compute Core?

Android 12’s Private Compute Core is a unified secure environment that acts as a sandbox for features that process sensitive data. With the help of Private Compute Core, Android isolates ML-enabled sensitive data from the rest of the OS and other apps you may have installed on your device. Thanks to this approach, features inside Private Compute Core do not have direct access to the Internet.

Having said that, the scope of Private Compute Core is noticeably limited at the moment. However, Google has promised to add more features to Private Compute Core with each new Android release.

What is Android Private Compute Services?

Machine learning models are often updated for enhancing overall efficiency and accuracy. Hence, there has to be a way for Google to push the updated ML models to the device in a secure manner that preserves privacy. To bridge the gap between your device and the cloud, Google has introduced Android Private Compute Services.

Private Compute Services offers a set of open-source APIs that lets components in Private Compute Core access the network. As per Google, these APIs will strip out identifiable information and utilizes privacy-focused techniques such as Federated LearningFederated Analytics, and Private information retrieval.

Private Compute Core: Supported Features in Android 12

With that said, let’s take a look at the features supported by the Private Compute Core:

  • Live Caption

Now Playing is a Pixel-exclusive feature that automatically identifies music playing near you without having to use a separate app to identify songs. It accesses the microphone, and Private Compute Core will help isolate the data processing involved here.

  • Smart Reply

Smart Reply is another crucial area where Private Compute Core is beneficial. Since the feature relies on suggesting relevant replies to your texts in messaging apps, privacy is a core aspect here. According to Google, Android will keep your reply hidden from the keyboard and the messaging app until you choose to tap the suggestion.
