Congrats to @umaarr6 and the @proper_data team (@zubair_shafiq, @proffnes, ++). Happy to see our work on auditing smart speakers recognized at @PET_Symposium #pets2024 as Runner-Up for the Caspar-Bowden PET Award. The paper had quite a ride so far: properdata.eng.uci.edu/2023/10/24/sma….

Honored to be recognized as one of the runners-up for the 2024 Caspar Bowden PET award. Our work proposes a framework to facilitate independent & repeatable audits on unmodified, off-the-shelf smart speakers without relying on cooperation from the platform vendors. Details here:

Thank you to those who attended Kashmir Hill's Fireside Chat last Friday! Here are some of her words from her talk with Dave Choffnes and Dean Beth: "It can be hard to get people to care about privacy as a value, and many people don’t appreciate it until it’s harmed in some way."
