A crook can't cut off your finger and access your iPhone

One of the biggest features that Apple announced on new iPhone 5S during its event earlier this week was the Touch ID system. Apple has now offered more details on Touch ID that may help some that are concerned about privacy feel better.

Apple says that the scanner doesn't store actual images of the user's fingerprint on the device. Instead, the ID system stores "fingerprint data" which remains encrypted inside the iPhone’s 64-bit A7 processor.

The Wall Street Journal reports that even if someone cracked the encryption chip, it would be highly unlikely that they could reverse engineer someone's fingerprint from the digital signature. Apple also says that it won't allow third-party applications to use the fingerprint scanner for the time being, and people who use Touch ID also have to create a passcode as a backup.

One important aspect of the Touch ID system is that the passcode must be used to unlock the phone if the device is rebooted or hasn't been unlocked and 48 hours. With all that said, the iPhone fingerprint scanner doesn't work perfectly. For instance, testers have said that the device doesn't work well if your fingers are damp from sweat, water, or lotion.

Apple even went so far as to point out that if a criminal hacked off your finger, they would be unable to unlock your phone. Apple says the Touch ID sensor searches for vitality signs to ensure that the finger is attached to the hand of a living person.

forget fingerprint, I'll take better camera

It's interesting how there's more press on the fingerprint sensor than the better camera in the 5S. Perhaps I'm not seeing what the fuss is about but sharper images, improved color/light balance, better indoor photos. All these advances are automatic and all are far more useful to me than replacing my App Store password with my fingerprint or unlocking my phone with my fingerprint (yawn!)

Maybe it's the shutterbug in me talking..

I am pretty sure what he means is that you can put an apple logo on a Yugo and you would be impressed and call it the greatest car ever built

I never liked this

although seeing my daughters response when she first saw one I understood who it was aimed at.

I loathed this

I thought this was terrible

and pretty much anything Apple made in the 1990s (other than the OS) I thought was very boring.

LOL... So did the rest of the planet, but I am surprised you admit it, even for products long out of production.

Anything current?
