The differences between contact tracing and exposure notification

TIP – Tech Informed Policy has released its second briefing, the purpose of which is to provide an overview of the differences between contact tracing and exposure notification, and outline the current options for these technologies. We summarize the technical differences between the two approaches, and review the security and privacy risks, adoptability, and feasibility of three technologies:

  1. GPS-Based Contact Tracing
  2. Bluetooth Low Energy (BLE) Based Contact Tracing
  3. BLE-Based Exposure Notification (Apple/Google model)

You can find the full briefing and download it on the TIP site.
