iOS 7.1.1 Behind the scenes of touch ID

Touch ID takes a 88x88 500ppi scan of your finger and temporarily sends that data to a secure cache located near the RAM, after the data is vectorized and forwarded to the secure enclave located on the top left of the A7 near the M7 processor it is immediately discarded after processing. The fingerprint scanner uses subdermal ridge flows (inner layer of skin) to prevent loss of accuracy if you were to have micro cuts or debris on your finger.

With iOS 7.1.1 Apple now takes multiple scans of each position you place finger at setup instead of a single one and uses algorithms to predict potential errors that could arise in the future. Touch ID was supposed to gradually improve accuracy with every scan but the problem was if you didn't scan well on setup it would ruin your experience until you re-setup your finger. iOS 7.1.1 not only removes that problem and increases accuracy but also greatly reduces the calculations your iPhone 5S had to make while unlocking the device which means you should get a much faster unlock time.

The purchase of authentec has given Apple a huge future advantage and touch ID is most likely a temporary place holder of a future display with an embedded fingerprint sensor

Here is the source about how touch ID works (starts on page 6) http://images.apple.com/ipad/business/docs/iOS_Security_Feb14.pdf.

The 2nd paragraphs source is magical ;)

In acelasi timp tinand cont ca Apple si NSA sunt prieteni, NSA si-a rezolvat problema amprentarii masive. Oricum, pentru cei care mai cred in "inovatii" si tehnologie, sa il ascultam un pic pe Applebaum (gasiti si de iPhone, nu mai stiu la ce minut):
