Solutions > Google Find Hub Network

Introduction

Google Find Hub Network is a device tracking service for the Android ecosystem. Users can securely track the location of lost or stolen devices using a decentralized network of Android devices worldwide. The service employs end-to-end encryption throughout to protect user privacy.

Basic Working Principle

Crowdsourced Network

The Google Find Hub Network is a crowdsourced network of billions of Android devices that use Bluetooth wireless technology to detect missing devices or items nearby, and report their approximate location back to the owner using the Find Hub app on Android. The entire process uses end-to-end encryption and remains anonymous, ensuring that no one else (not even Google or third-party manufacturers) can view the location or information of the device.

Google’s Find Hub Network is based on the Fast Pair specification, which allows accessory devices to communicate with Android devices to let the owner locate their accessory using the network. The network consists of all Android 6.0+ devices that support Fast Pair.
