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.

desperate to find faults?

Before the units are even out (and after media praised the sample units for their accuracy) we see negative press on one reviewer and it gets front page news on DT.

Yes, I would expect smudging the scanner with hand lotion would cause it to not work in the same vein with 'closing your eyes will not work with eye retina scanner' headline.

I'll wait for the big players to do a real review before harping on this technology.

Good post.

Yes of course you can't drive if you cant see out the windshield, of course you can use motion detection if your a quad, of course you cant drink liquids if you don't have a cup or bowl, but we don't have common sense any longer as this proves!

Thanks for the laugh!
