Privacy-Preserving Exposure Notification

Our efforts advocating and supporting privacy-preserving exposure notification technology to help fight the COVID-19 crisis.


The TCN Coalition is a global team of technologists and experts supporting exposure notification applications during the COVID-19 pandemic. They support and advocate for privacy-preserving technologies, realizing that exposure notification apps must be interoperable, trusted by the public, and privacy-preserving in order to succeed. Crimson Vista's Ellie Daw has been involved in the coalition nearly since the beginning, leading a working group for interoperable design, providing feedback to policy makers, and publishing thought-leadership in the space.
