As per the new reports, Google and Apple now refer to “contact tracing” as “exposure notification,” which the companies expect better functionality of their upcoming API. which is Intended to notify a person of potential exposure, increase the broader contact tracing that public health authorities are undertaking.
Keys will be generated instead of deriving from a temporary tracing key, making it difficult for someone to guess how the keys are derived and use that same data to try and track people.
Bluetooth metadata will be encoded, enabling more security for someone to try and use that information to identify a user.
The discovery time will be recorded in the 5-minute interval and the maximum reported exposure time curbed to 30 minutes.
Google and Apple will allow developers to specify duration thresholds and signal strength to exposure events.
The information under the will include the power level of the Bluetooth signal in the data that is exchanged between two phones. This can be used simultaneously with the Received Signal Strength Indication to estimate the distance between two phones when contact was made.
The API will now detect the number of days since the last exposure event to determine what actions the user should take next.
Both the tech giants Google and Apple are targeting next week for the release of the seed version of Their respective Android and iOS operating system updates, which will support APIs to test by public authority developers. The update will support iOS devices released in the last four years, since the release of the iPhone 6 series including the 6 plus and the iPhone 6.
Apple and Google announced the plans for this exposure notification initiative on first week of April 2020. This joint system will use Bluetooth to alert users when they have potentially come in close contact with someone who later tests positive for the coronavirus, also both the companies have shared the updated frequently asked questions (FAQ) for its users with more details about the system.
