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/….

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."

“When we think of what happens between the walls of our homes, we think of it as a trusted, private place. In reality, we find that smart devices in our homes are piercing that veil of trust and #privacy." @proffnes

Interesting piece by @DarianWoods and @VelocityWong of @theindicator about net neutrality, with a brief mention about our 2019 study showing cellular providers throttling video traffic in 2018/2019---a practice that continues to this day npr.org/transcripts/11979563…

Thanks @SteveLohr @JRosenworcelFCC for announcement and reporting on returnning #netneutrality nytimes.com/2023/09/26/techn… only the assertion that blocking, throttling and paid prioritization are not a problem is contradicted by good work & research from @proffnes & @MeasurementLab
