Apple's new iPhone 5S, which comes with a fingerprint scanner, won't store actual images of users' fingerprints on the device, a company spokesman confirmed Wednesday, a decision that could ease concerns from privacy hawks.

Rather, Apple's new Touch ID system only stores "fingerprint data", which remains encrypted within the iPhone's processor, a company representative said Wednesday. The phone then uses the digital signature to unlock itself or make purchases in Apple's iTunes, iBooks or App stores.

In practice, this means that even if someone cracked an iPhone's encrypted chip, they likely wouldn't be able to reverse engineer someone's fingerprint.

This seems relatively safe - but then again, only if you trust that government agencies don't have some sort of backdoor access anyway. This used to be tinfoil hat stuff, but those days are long gone.

I dislike the characterisation of privacy "hawks", though. It reminds me of how warmongering politicians in Washington are referred to as 'hawks", and at least in my view, it has a very negative connotation.

Although I presume that only works only with sensors that are very simple and only have a 2D model.

With 3D printers becoming affordable, if fingerprints as ID method becomes mainstream enough I'd bet you'd soon see specialized software to create 3D finger models out of a fingerprint scan, ready to be 3D-printed and used anywhere.

Trust me, as someone who is building a 3D printer. That problem is still quite far away! The current methods are not at the level of detail required for that. Give it a decade or so, then maybe.
