Google has revealed plans for an authentication convergence strategy which would see rich behavioural data gathered from mobiles and then used for continuous authentication on both smartphones and desktops.Called Trust API (formerly Project Abacus) the behavioural biometrics system aims to kill passwords and replace them with a combination of gait, typing patterns and other data gathered on smartphones – including face data and location.On Project Abacus, Google had said users would unlock devices or sign into applications based on a cumulative “Trust Score”, calculated using a variety of factors, including your typing patterns, current location, speed and voice patterns, facial recognition, and other things.Different apps could require different Trust Scores depending on how critical is the data it handles – banking apps, for example, would require a higher score compared to a game.Daniel Kaufman, head of Google's Advanced Technology and Projects division, says that testing for the new biometric security measure is underway for this summer, TechCrunch reports.Google will begin trials with “several financial institutions” next month with the goal of becoming available to every Android developer by the end of the year.Neil Costigan, CEO at BehavioSec, told Planet Biometrics: “We are thrilled to see our long evangelism of continuous authentication via behavioural biometrics and our DARPA work arriving where we predicted … Ubiquitous in every device.”
