Apple and Google Partner on Decentralized COVID-19 Contact Tracing System
Apple and Google team up to build a cross-platform, Bluetooth-based contact tracing tool to help track COVID-19 exposure. The joint project aims to solve interoperability issues while prioritizing user privacy through a decentralized, opt-in approach.
Apple and Google join forces to create a decentralized contact tracing tool that helps individuals determine if they are exposed to COVID-19. The system uses Bluetooth beaconing to transmit anonymous rotating IDs over short ranges, allowing devices to log close interactions without collecting centralized location data. Public health authorities rely on contact tracing to track disease spread and notify potentially exposed individuals so they can get tested.
The companies roll out the project in two distinct phases to ensure broad adoption and technical reliability. The first phase provides an API that public health agencies integrate into their own apps, while the second phase builds a system-level tracing feature directly into iOS and Android operating systems. This unified approach solves the fragmentation problem that limits the effectiveness of standalone tracing apps.
Health organizations and universities previously attempt to build similar privacy-conscious tools but encounter technical hurdles like Bluetooth power drain and poor interoperability across device manufacturers. By working together, Apple and Google overcome these challenges and create a massive, unified network where users opt in to receive notifications if they spend significant time near someone who later tests positive. This prompt allows them to quickly seek medical care and self-quarantine.
