Google and Apple Unveil Decentralized COVID-19 Exposure Notification System
Google and Apple release sample code and privacy guidelines for a new COVID-19 exposure notification system that relies on state-developed apps. The decentralized approach protects user privacy by avoiding location tracking and government data sharing.
Google and Apple share sample code and privacy guidelines for a jointly developed COVID-19 exposure notification system. The technology uses Bluetooth to help slow the spread of the virus by notifying individuals who come into close contact with an infected person. State and public health authorities are responsible for developing the actual applications that conform to these new Google-Apple specifications.
The system requires a confirmed positive person to input a state-verified test result identifier, which triggers the app to send anonymous alerts to other users who were recently nearby. This method prevents bad actors from sending false positive alerts and maintains the integrity of the network. Users voluntarily download the application and opt into the system, meaning participation is entirely optional.
This decentralized approach differentiates itself from other tracing apps by strictly limiting its scope and protecting user data. The application cannot access other location information from the device, does not share personally identifiable information, and prevents data from being shared with governments. Additionally, the companies design the system to be temporary, ensuring it automatically disables once the pandemic abates.
