Apple and google forbidden an update of the app NHS covid-19 for england and wales because it should violate the data protection rules associated with the exposure notification framework. This reports among other things the BBC.
Accordingly, the update should actually add a check-in function, with which users and users can not only document their presence in one place or on an event on their smartphone, but can also pass this list in case of infection. Exactly this possibility to pass on the list of checked-in places but aborted against the specification that location data was not shared with the respective health workercies, apple or google.
Projected transfer of location data
The prevented update should be the contact tracking app of the british health service NHS used in england and wales actually to yield that function, as it is currently demanded in many places. Users are designed to scan a QR code created for DAFUR, which is provided in places where many people meet. Only locally on the smartphone creates a list of visited places and events. Find the contact tracker that someone with covid-19 was such a place or on such an event, download the associated code into its own database. The app regularly compensates for your list with this and informs about the possible contact, if necessary.
