Engineering lecture focuses on contact tracing: Monitoring COVID-19 infections while respecting privacy

Communities need a reliable method to track COVID-19 infections and slow the spread of the virus now affecting populations worldwide.

One option is contact tracing, a method for monitoring who has come in contact with whom, and, when appropriate, alerting a network of people if someone nearby has been diagnosed with the virus. Mobile phone apps offer opportunities to improve the accuracy of contact tracing but they come with privacy red flags — for example leaking a user’s location information or taking away people’s control over their own data.

This fall the University of Washington’s annual engineering lecture will feature Stefano Tessaro, an associate professor in the Paul G. Allen School of Computer Science & Engineering. Tessaro, whose research centers on cryptography, computer security and privacy, will discuss the benefits and drawbacks of contact tracing, its widespread use, and digital contact tracing methods being developed at the UW and Microsoft Research to protect the privacy of individuals.

Tessaro’s talk will be Wednesday, Oct. 21, at 5 p.m. This lecture is free and open to the public, but registration is required.

After the lecture, a recorded version will be embedded below.
