Decentralized Privacy-Preserving Asymmetric Digital Contact Tracing (DP-ACT) protocol is a decentralized contact tracing protocol with both active and passive participants. Active participants broadcast BLE beacons with pseudo-random IDs, while passive participants model conservative users who do not broadcast BLE beacons but still listen to the broadcasted BLE beacons. Hence, passive participants learn about their potential exposure and can take proper action. On the other hand, once infected, passive participants may release their list of high-risk contacts based on the pseudo-random IDs they have received. This allows active participants to exercise home quarantine if their pseudo-random IDs are released by the passive participants. As a result, the proposed protocol enables high-precision digital contact tracing, by enabling and leveraging the participation of conservative/passive users.
