Cover Image for COVID-19: Extending automated tracing with manual tracing

We believe we can provide the extension to Bluetooth contact-tracing that will fill the gaps, reliably warning people of their risk without revealing the source of the risk.

COVID-19: Vaccine trial and mobile application

Today, we reached two significant milestones. The first one is not related to our contact-tracing service: human trial of a COVID-19 vaccine, led by Oxford, Bristol, London and Southampton universities, has started.

COVID-19: Bluetooth-tracing and distance measures

Measuring distance is a challenge. Bluetooth signal is attenuated with distance, but there are hundreds of different devices, designs, and antennas. A device 5 meters away can have a stronger signal than another one just 2 meters away. To this, we see added complexity due to reverberation and interferences.

COVID-19: Improved authority bridging: maximised impact

Watching the various efforts currently made by the community and carefully reviewing the advantages and pitfalls of each, we feel that we are now close to a comprehensive final proposal and expect to release our technical paper soon.

COVID-19: Some privacy concerns

Companies such as health and life insurance or mortgage dealers, in the absence of available science, may start relying on worst-case assumptions and start discriminating against infected people. The identities of infected people must remain private to avoid this risk.

COVID-19: The critical role of authorities

We can help increase the impact by bridging authorities' data internationally, in the case of an infected user crossing a border. With the consent of the user, we can forward pseudonymised identifiers to all relevant authorities.

COVID-19: A welcome effort from Apple and Google

To prevent the spread of the COVID-19, we have explored Bluetooth-based contact-tracing techniques. Other solutions based on GPS, antenna towers or local wifi triangulation, are not precise or reliable enough.
