Even if venti scores are completely unguessable, using them as an authentication mechanism is a mistake, because you can't change them. It would be like having a fixed, unchangeable password assigned to your account: once the password leaked out into the world, one way or another, you'd have no way to stop anyone on the internet from masquerading as you or telling the password to others.
