The Senate passed the USA Freedom Act today by 67-32, marking the first time in over thirty years that both houses of Congress have approved a bill placing real restrictions and oversight on the National Security Agency’s surveillance powers.

It’s not actually banned in the EU yet—the legislative process is much more complicated than that—but it’s a step: a total ban on biometric mass surveillance. To respect “privacy and human dignity,” MEPs said that EU lawmakers should pass a permanent ban on the automated recognition of individuals in public spaces…
We study subliminal learning , a surprising phenomenon where language models learn traits from model-generated data that is semantically unrelated to those traits. For example, a "student" model learns to prefer owls when trained on sequences of numbers generated by a "teacher" model that prefers owls. This same…

freeOTP is a soft token authenticator that can be used for two-factor authentication, and is available as a free Android app or iOS app. Two-factor authentication — requiring a user to have “something you have”, as well as “something you know” i.e. a password — is being supported on many more services these days…
One of the more curious behaviors of Apple’s new iPhone 11 Pro is that it intermittently seeks the user’s location information even when all applications and system services on the phone are individually set to never request this data. Apple says this is by design, but that response seems at odds with the company’s…
I learn about cryptographic vulnerabilities all the time, and they generally fill me with some combination of jealousy (“oh, why didn’t I think of that”) or else they impress me w…
