Google announced Friday that its exposure notification API, designed in partnership with Apple, has been improved to make it more useful to public health departments,media Macrumors reported. Most notably, THE API supports interoperability between countries and Bluetooth calibration has been improved. The full list of updates is as follows:
When exposure is detected, public health authorities can now more flexibly determine the level of risk associated with the exposure based on the technical information of the API.
Bluetooth calibration values for hundreds of devices have been updated to improve detection of nearby devices.
Based on government feedback that has rolled out exposed notification applications, the API now supports interoperability between countries.
To help public health agencies build applications more efficiently, we’ve added reliability improvements to applications and developer debugging tools.
We improve clarity, transparency and control for our users. For example, the exposure notification setting on Android now includes a simple on/off switch that appears at the top of the page. In addition, if ENS is turned on, users will also see a regular reminder.
In the past few weeks, Google said, it has also released more technical guidance on how the Exposure Notification API works and provides more information on its exposure notification site.
According to Google, 16 countries and territories in Africa, Asia, Europe, North and South America are using apps built with exposure notification APIs, and 20 U.S. states are “exploring” apps, with the first available in “the next few weeks.”
