Apple and Google Release Official COVID-19 Exposure Notification API
Apple and Google officially launch their exposure notification API, allowing public health agencies to build and release privacy-focused COVID-19 contact-tracing apps. Dozens of countries and US states already have access to the decentralized system.
Apple and Google officially release the first public version of their exposure notification API, allowing public health agencies to build and release COVID-19 contact-tracing apps. The tech giants do not create the apps themselves, but instead provide the underlying system that developers use to notify individuals of potential virus exposure. Dozens of countries and U.S. states already receive access to support their development efforts.
The system uses a decentralized identifier method that relies on randomly generated temporary keys rather than personal identity or location data. Public health agencies define what constitutes potential exposure based on time and distance, and they adjust transmission risk factors according to their own specific standards. Users also have the option to voluntarily submit additional data so authorities can contact them directly with next steps.
Privacy remains a top priority throughout the API's design. The companies encrypt all Bluetooth metadata, such as signal strength and transmitting power, to prevent anyone from identifying the specific type of device a person uses. These continuous improvements ensure that the tool helps slow the spread of the coronavirus without compromising user anonymity.
