But, just as the authentication is an option, it might not take much to change off to an option for going beyond 'local' as I see it. A checkbox option for remote verification, for example, like for Office updates or similar where Microsoft really wants to make sure it is you, the paid party. Something that is much more easily employed after the system has been up and running for some time, creating a sense of 'implied trust' with the user.
And since the sell is for secure local info - where "information about a fingerprint, iris or face will be stored locally and not shared with others."
Are we talking about data or also storing actual images of fingerprints, data, etc? And is the data and/or image(s) secure? Can you encrypt an image so as to not make it readable?

And while we're on the topic -- what about everyone who has pictures of themselves posted along with names. On LinkedIn, for example. Is fingerprint the best way to go?
