Apple, Google make it easier for states to use virus-alert technology
Several state governments may soon send residents an alert asking them to turn on “exposure notifications.”
Apple and Google said last week they would make it easier for states to use their new technology that detects phones that come close to one another and can notify people who may have been exposed to the coronavirus.
States that sign on will be able to send a notice directly to smartphones asking people to opt in to the technology. Previous versions of the technology had required people to seek out a state health agency’s app.
The new approach could spur the popularity of such virus-alert technology in the United States by significantly lowering the hurdles for its use. Maryland, Virginia, Nevada and Washington, D.C., already plan to use the new system, Apple and Google said, and about 25 other states were exploring using the earlier app version.
Apple and Google called the changes a “next step in our work with public health authorities.” They said the shifts would help “public health authorities to supplement their existing contact-tracing operations with technology without compromising on the project’s core tenets of user privacy and security.”
In April, Apple and Google announced they were developing the technology, which uses Bluetooth signals to enable iPhones and Android devices to detect nearby phones. If someone using the technology tests positive for the virus, that person can enter the positive result into the system using a unique authentication code. An automatic notification would then go to other phones that had opted in and had been in close contact.
The Apple-Google technology does not collect personal health details or track users’ locations. That has made the system attractive in Europe and elsewhere. Germany, Denmark and Ireland have already released apps using the technology, and millions of people in Europe have downloaded them.
Now, to use Apple and Google’s technology, state public health authorities simply need to provide certain parameters to the companies, such as how close people need to be to trigger an exposure notification and recommendations for those with possible exposures. Google would then create an app for the state, while Apple would enable the technology on the iPhone software. The system would then use approximate location data to send an alert to residents’ phones in that state, asking if they would like to enroll.
