> If a photo of your passport or whatnot is private information that must be kept secret, or else identity theft... well then it can't be sent to AirBnB en masse. I think the main issue is that it’s not really you, but service providers who get to decide what’s an information that need to be kept secret. For instance if most banks decide to exclusively use bits of your fingernails to verify you, your fingernails become something you need to keep secret, your personal position be damned. And the more agencies that decide to use your fingernail bits, the more valuable they get. For Airbnb, if the practice propagates enough, your photo with your passport in it will become the new way to fake you.
