Pan-European Privacy-Preserving Proximity Tracing (PEPP-PT/PEPP) is a full-stack open protocol[3] designed to facilitate digital contact tracing of infected participants.[4] The protocol was developed in the context of the ongoing COVID-19 pandemic. The protocol, like the competing Decentralized Privacy-Preserving Proximity Tracing (DP-3T) protocol,[5] makes use of Bluetooth LE to discover and locally log clients near a user. However, unlike DP-3T, it uses a centralized reporting server to process contact logs and individually notify clients of potential contact with an infected patient.[6]: section. 3.2 [7] It has been argued that this approaches compromises privacy, but has the benefit of human-in-the-loop checks and health authority verification.[7] While users are not expected to register with their real name,[8]: p. 13 the back-end server processes pseudonymous personal data that would eventually be capable of being reidentified.[9] It has also been put forward that the distinction between centralized/decentralized systems is mostly technical and PEPP-PT is equally able to preserve privacy.[10]
