Intrusion Detection in Android 16: What we know about this new security feature

Google is preparing to introduce a potentially game-changing security feature with Android 16: Intrusion Detection. This new tool is designed to give users deeper insight into suspicious activity on their devices, using encrypted logs and private storage for maximum protection. Though not yet officially confirmed, the discovery in Google Play Services hints at a major privacy enhancement on the horizon.

What is Intrusion Detection and how it works

The feature was uncovered in a beta version of Google Play Services rather than Android 16 itself. Internally referred to as Intrusion Detection, this system may be part of Google’s Advanced Protection Program, which offers heightened security for high-risk users such as activists, journalists, and political workers.

Once enabled by the user, Intrusion Detection would allow Android devices to log encrypted information about sensitive data, including browsing history, app installations, saved Wi-Fi and Bluetooth connections, and lock screen credentials. All of this would be stored securely in the user’s Google Drive, in a space that is private and accessible only to them.

Why it matters and who it protects

This feature could play a key role in protecting against unauthorized access or forensic investigations after suspicious activity. The collected logs would help users and security professionals trace back security incidents more effectively. While the function remains optional and requires explicit permission, its implications are significant.

Intrusion Detection appears to be an extension of Google’s broader move toward eliminating traditional passwordsthrough biometric-based passkeys, ensuring tighter account protection. Whether it debuts with the full Android 16 release or later, it underscores Google’s growing focus on proactive, user-controlled digital security.
