Apple and Google Partner on Opt-In COVID-19 Contact Tracing Technology to Be Added to iPhone and Android Smartphones

Apple and Google today announced a joint effort that will see them using Bluetooth technology to help governments and health agencies reduce the spread of the COVID-19 virus around the world.


Apple says that user privacy and security will be central to the design of the project. Participation will be opt-in, and privacy, transparency, and consent are "of the utmost importance of this effort."

Since COVID-19 can be transmitted through close proximity to affected individuals, public health officials have identified contact tracing as a valuable tool to help contain its spread. A number of leading public health authorities, universities, and NGOs around the world have been doing important work to develop opt-in contact tracing technology. To further this cause, Apple and Google will be launching a comprehensive solution that includes application programming interfaces (APIs) and operating system-level technology to assist in enabling contact tracing. Given the urgent need, the plan is to implement this solution in two steps while maintaining strong protections around user privacy.

Starting in May, Apple and Google will release APIs that enable interoperability between Android and iOS devices using apps from public health authorities. These apps will be available for users to download from the iOS App Store and Google Play.


In the coming months, Google and Apple will work to enable a broader Bluetooth-based contact tracing platform by building this functionality into their underlying platforms. Apple says that this solution is more robust than an API and will allow more individuals to participate, if they choose to opt in, and it will enable interaction with a broader ecosystem of apps and government health authorities.

All of us at Apple and Google believe there has never been a more important moment to work together to solve one of the world’s most pressing problems. Through close cooperation and collaboration with developers, governments and public health providers, we hope to harness the power of technology to help countries around the world slow the spread of COVID-19 and accelerate the return of everyday life.

All information about the work being conducted by Apple and Google will be openly published and built in consultation with interested stakeholders. Initial details on the contact tracing technology are available on Apple's new webpage for the feature, which has links to technical documentation on Bluetooth specifications, cryptography specifications, and the framework API.

TechCrunch has specific details on how the tracking procedures will work. A random, rotating identifier will be assigned to a person's phone, and it will be transmitted via Bluetooth to other nearby devices.

The identifier, which rotates every 15 minutes and has no personally identifiable information, will pass through a relay server that can be run by health organizations worldwide. The list of identifiers a person has been in contact with doesn't leave the phone unless the user explicitly decides to share it. Users that test positive will not be identified to other users, Apple or Google.

All identification matching is done on device, allowing users to see within a 14-day window, whether their iPhone has been near the device of a person who has self-identified as having tested positive for COVID-19. Users who are notified that they have been exposed will then receive steps on what to do through a public health app.

Apple and Google are not using any location data for the tracking feature, including from the users who report being positive. The tool is meant to determine not where affected people have been, but rather if they've been around other people so that those people will know to self isolate due to the exposure.

If technology can help everyone, I don't care about someone's privacy issues

If you're a US citizen, I don't think you comprehend how privacy and civil liberties are intertwined.

And I don't trust Google to make this only opt-in.

There is no way I will consent to this. The government doesn’t need to track me. Covid-19 be damned.

Contact Tracing on one hand is innocent; you ask who someone's been in touch with and them them who they've been in touch with...

Enabling this on an API and Bluetooth level is straight up Dark Knight Rises, and we don't have Batman looking out for us.

Google made their fortune spying on people and selling user data. So why would I suddenly trust anything Google to be anything but spyware. Especially when the "opt in" choice is removed for "reasons of national security".

Beyond creepy...and a VERY slippery slope.

Once these apps are available, some schools and busnesses may *require* opting in to this contact tracking in order for anyone to return to school, work, or etc, when they open back up. Or the business's insurance company or lawyer may require this to reduce liability.
