# Decentralized Privacy-Preserving Proximity Tracing
|
|
|
|
This repository contains a proposal for a secure and privacy-preserving decentralized privacy-preserving proximity tracing system. Its goal is to simplify and accelerate the process of identifying people who have been in contact with an infected person, thus providing a technological foundation to help slow the spread of the SARS-CoV-2 virus. The system aims to minimise privacy and security risks for individuals and communities and guarantee the highest level of data protection.
|
|
|
|
By publishing this document we seek feedback from a broad audience on the high-level design, its security and privacy properties, and the functionality it offers; so that further protection mechanisms can be added if weaknesses are identified. The [white paper document](DP3T%20White%20Paper.pdf) is accompanied by an [overview of the data protection aspects of the design](DP3T%20-%20Data%20Protection%20and%20Security.pdf), and a [three page simplified introduction to the protocol](DP3T%20-%20Simplified%20Three%20Page%20Brief.pdf).

## Apple and Google Proposal
|
|
|
|
Apple and Google have released a [joint specification](https://www.apple.com/newsroom/2020/04/apple-and-google-partner-on-covid-19-contact-tracing-technology/) describing their system support for privacy-preserving proximity tracing on iOS and Android . Their proposal is very similar to our early proposal named ["Low-cost decentralized proximity tracing"](https://github.com/DP-3T/documents/blob/master/DP3T%20White%20Paper.pdf).
|
|
|
|
DP-3T appreciates the endorsement of these two companies for our solution and is happy to work with both of them to implement our app on both platforms.
|
|
|
|
But, we also strongly believe that Apple and Google should adopt our subsequent enhancements, detailed in later versions of our [white paper](https://github.com/DP-3T/documents/blob/master/DP3T%20White%20Paper.pdf), which increase user privacy. We also strongly encourage both companies to allow an external audit of their code to ensure its functionality corresponds to its specification.

## The relationship between DP-3T and PEPP-PT
|
|
|
|
The Decentralised Privacy-Preserving Proximity Tracing (DP-3T) project is an open protocol for COVID-19 proximity tracing using Bluetooth Low Energy functionality on mobile devices that ensures personal data and computation stays entirely on an individual's phone. It was produced by a core team of over 25 scientists and academic researchers from across Europe. It has also been scrutinized and improved by the wider community.
|
|
|
|
DP-3T is a free-standing effort started at EPFL and ETHZ that produced this protocol and that is implementing it in a soon-to-be-released, open-sourced app and server.
|
|
|
|
DP-3T participates in the loose umbrella of the 'Pan-European Privacy-Preserving Proximity Tracing' (PEPP-PT) project. DP-3T is not the only protocol under this umbrella. PEPP-PT also endorses centralized approaches with very different privacy properties. Pandemics do not respect borders, so there is substantial value in PEPP-PT's role of encouraging dialogue, knowledge-sharing, and interoperability.
|
|
|
|
Nevertheless, as the systems endorsed by PEPP-PT have technical differences that yield very different privacy properties, it is a mistake to use the term 'PEPP-PT' to describe a specific solution or to refer to PEPP-PT as if it embodies a single approach rather than several very different ones.
