Keeping people safe and their data secure and private is a top priority for Android. That is why we took our time when designing the new Find My Device, which uses a crowdsourced device-locating network to help you find your lost or misplaced devices and belongings quickly – even when they’re offline. We gave careful consideration to the potential user security and privacy challenges that come with device finding services.
During development, it was important for us to ensure the new Find My Device was secure by default and private by design. To build a private, crowdsourced device-locating network, we first conducted user research and gathered feedback from privacy and advocacy groups. Next, we developed multi-layered protections across three main areas: data safeguards, safety-first protections, and user controls. This approach provides defense-in-depth for Find My Device users.
How location crowdsourcing works on the Find My Device network
The Find My Device network locates devices by harnessing the Bluetooth proximity of surrounding Android devices. Imagine you drop your keys at a cafe. The keys themselves have no location capabilities, but they may have a Bluetooth tag attached. Nearby Android devices participating in the Find My Device network report the location of the Bluetooth tag. When the owner realizes they have lost their keys and logs into the Find My Device mobile app, they will be able to see the aggregated location contributed by nearby Android devices and locate their keys.
Find My Device network protections
Let’s dive into key details of the multi-layered protections for the Find My Device network:
In addition to careful security architectural design, the new Find My Device network has undergone internal Android red team testing. The Find My Device network has also been added to the Android security vulnerability rewards program to take advantage of Android’s global ecosystem of security researchers. We’re also engaging with select researchers through our private grant program to encourage more targeted research.
Prioritizing user safety on Find My Device
Together, these multi-layered user protections help mitigate potential risks to user privacy and safety while allowing users to effectively locate and recover lost devices.
As bad actors continue to look for new ways to exploit users, our work to help keep users safe on Android is never over. We have an unwavering commitment to continue to improve user protections on Find My Device and prioritize user safety.
