What is BlueTrace?

Contact tracing is an important tool to reduce the spread of infectious diseases like COVID-19. BlueTrace is a privacy-preserving protocol for community-driven contact tracing using Bluetooth devices, that allows for global inter-operability.



BlueTrace is designed for decentralised proximity logging and supplements centralised contact tracing by public health authorities. Proximity logging using Bluetooth addresses a key limitation of manual contact tracing: that it is dependent on a person’s memory and is therefore limited to contacts that a person is acquainted with and remembers having met. BlueTrace therefore enables contact tracing to be more scalable and less resource-intensive.
