You are your Password

Project Vault (being discussed at Google I/O right now – no links online yet) analyzes device usage in real time to produce a live-updated trust score that can be adaptively applied to various actions the user of the device attempts to make. Use case: trust score drops below 50, may allow user to play a game, but not launch a banking app. Very smart idea.

EDIT: It turns out that I’d conflated Project Vault with Project Abacus. Project Vault is a microSD ARM computer that handles trusted operations on Android phones via a faux FAT-filesystem interface. Also cool, but not what I originally posted about.
