Yes, in that case it's often called Photo-TAN or QR-TAN. See https://en.wikipedia.org/wiki/Transaction_authentication_num...

Previously there were also so called "flicker TAN" approaches: https://de.wikipedia.org/wiki/Transaktionsnummer#chipTAN_com...

Evil and careless can be one and the same. They (FB) could not care-less about the consequences of their actions on other peoples' lives.

In 2015, when I was asked by friends if I'm worried about Self driving Cars and AI, I answered: "I'll start worrying about AI when my Tesla starts listening to the radio because it's bored." ... that didn't take too long

I like the Bayesian Surprise definition for this. It's not about predicting the exact next state of the world (or the next frame of the noisy TV) but about how much the next state changes your model of the world.

I spent some (too much) time trying to get pretty much the same thing running using GOW [1]. Was quite a bit harder than I thought, requiring a hdmi dummy plug to get the xserver config right etc.

See e.g. Ian Osband's work (he calls it 'risk' VS 'uncertainty' for some good examples that help in differentiating this: https://scholar.google.com/citations?view_op=view_citation&h...

I think the paper "Explaining Explanations in AI" by Brent Mittelstadt (https://arxiv.org/abs/1811.01439v1) gives a really good overview of the different goals and approaches.

New comment by sdl in "Extracting Qualcomm's KeyMaster Keys – Breaking Android Full Disk Encryption"

sdl — Thu, 30 Jun 2016 15:55:57 +0000

So if I understood correctly, there are 5 requirements for such a system to be secure:

  1: secure/unmodifiable cryptographic processor
  2: with unremovable rate limiting
  3: and exclusive access to a hardware key
  
  4: cryptographic processor has the only function of encrypting user data based on
  5: hardware key and a user supplied pin/key

Errors done by Qualcomm:

  Violated 3: Hardware key not exclusivly readable by cryptographic processor
  Violated 5: Encryption based on derived key

Anything I overlooked?

So true. At first I couldn't believe it, but it is IMPOSSIBLE to completely remove a paired bluetooth device from windows. After having connected my wireless keyboard to my mac for a day, I tried to reconnect it to windows. It fails silently and doesn't show up any more in available bluetooth devices. The connection to my mac obviously changed the pairing code, while windows still tries the old one. I googled for hours, tried everything from uninstalling bluetooth drivers to removing entries from the registry. Windows always silently re-adds the keyboard to the installed devices and fails at pairing. So I've got 2 choices left: Buy a new keyboard or reinstall Windows. Yay!
