Motorola implemented fingerprint reader on Atrix, but it is strictly local authentication. I don't think fingerprint data on cloud causes a significant raise in exposure of your data because your phone number is already tied to you. On the other hand, a unified fingerprint database could pose serious risk to privacy if made queryable. I would only trust such system if I could encode my fingerprint's hash with another mean of authentication such as a password so that only with the password could my fingerprint be verified. That would, of course, lessen the appeal of the fingerprint scanner by making it harder to use than a simple password, but would make for a nice two-factor authentication.
