IPhone 5S/C biometric reader confirmed

An imgur album with a couple screengrabs confirms nothing. I could create those folders and that file in about 5 minutes, too. It might be authentic, but there's no proof that it is.

It's not that I doubt that biometrics will be a part of the 5s - I mean, my laptop did this ages ago, and biometric authentication is already running on present-day phones. The imgur album just doesn't confirm anything without a credible source.
