The past few months at our #domesticviolence computer security clinic have brought many reminders of what a boon 2-factor authentication can be for abuse survivors.
And yet many don't know about it. We need to get the word out.
Check out our guides: ipvtechresearch.org/resources

If you have user id's (and don't mind leaking some bits about them) you can bucketize just using hash prefix. For password-only check (like HIBP), our frequency-smoothed bucketization suggestion is more complicated, intuitively tuning the # of bits revealed to password popularity

Yeah the approach is bucketization + OPRF-based private set membership (and yes, slow hashing). The key issue is how to bucketize safely to make the private set membership tractable

Yeah actually a key challenge was overcoming how wildly impractical directly applying PSI would be for this application. Hear about it at #realworldcrypto 2020, or see arxiv.org/abs/1905.13737 and usenix.org/conference/use…

My group is looking for PhD students this year. We're researching text generation, struct. prediction, generative NLP / vis, and compression. Also excited to hear what interests you.
I'm at Cornell Tech in NYC (student's view below). If you are interested, apply to Cornell CS. pic.twitter.com/Dmn0ULGcQI

I'm proud & excited to have joined @cornell_tech as the Director of its computer security clinic for survivors of intimate partner violence.
Faculty & graduate students here are doing incredible work to help survivors reclaim their privacy - and safety.

Researchers at Cornell and NYU have pointed out that even legitimate location-sharing apps can be used by abusers who can get physical access to a victim's phone. So I tested them, and found they don't do nearly enough to warn users they're being tracked. wired.com/story/common-a…
