Receiving exposures documentation

When Exposure Notification Framework finishes comparing diagnosis keys with keys stored on the device and it detects some exposures when ExposureService.detectExposures() is called, then result of this method will contain potential exposures. In order to provide user a correct risk level that is shown in the PWA module application has to get detailed information about detected exposures and save them to the local, encrypted database.

Steps:

• Start by detecting exposures.
  • Service method: ExposureService.detectExposures()
• The list of Exposure objects is provided, based on list of ENExposureDetectionSummary objects.
• The app saves every exposure information to encrypted database with only the following data:
  • Day level resolution that the exposure occurred
  • Length of exposure (value is stored in seconds)
  • The total risk score calculated for the exposure
    • Service method: ExposureSummaryService.getExposureSummary()
