On Tuesday, I spoke at the Seattle Privacy/TechnoActivism 3rd Monday meeting, and shared some initial results from the Seattle Privacy Threat Model project.
Overall, I’m happy to say that the effort has been a success, and opens up a set of possibilities.
- Every participant learned about threats they hadn’t previously considered. This is surprising in and of itself: there are few better-educated sets of people than those willing to commit hours of their weekends to threat modeling privacy.
- We have a new way to contextualize the decisions we might make, evidence that we can generate these in a reasonable amount of time, and an example of that form.
- We learned about how long it would take (a few hours to generate a good list of threats, a few hours per category to understand defenses and tradeoffs), and how to accelerate that. (We spent a while getting really deep into threat scenarios in a way that didn’t help with the all-up models.)
- We saw how deeply and complexly mobile phones and apps play into privacy.
- We got to some surprising results about privacy in your commute.
