Apple to use “trust score” such as in Black Mirror

I'm guessing this is basically a "bot score" and if it is too high/low they'll start hitting you with a CAPCHA when you try to buy something through your phone. I seriously doubt it will involve other people rating their interactions with you, making it rather unlike the Black Mirror episode they mentioned.
Probably right on the usage of the word "trust". Someone probably thought "This is how much I trust that the legitimate owner is doing this" and it ran from there.
There's a clear separation between bank account activity and a person, but the separation between what's done on an account attached to a phone and a person is starting to blur. We have moved so quickly toward identifying with activity on our devices that we aren't entirely comfortable with systems monitoring for fraud, but we probably also don't want those systems not to exist.
