This is disconcerting. I don't like the idea of biometric and other characteristic data being used to identify me, but at least with fingerprint sensors, retina scanners and other such devices I am aware what is happening and give consent each time. This system proposes to silently identify me by the way I type, click or use a device, constantly learning and improving. No doubt the processed data, like a signature, will reside in the cloud and eventually be used identify users on any device they happen to be using. Convenience above all else, yet again.
