Earlier today Apple introduced two new iPhones, the affordable 5C and the flagship 5S.
The 5S not only came in two new colors (Gold and Space Gray) but it also confirmed the rumors of a fingerprint scanner in the home button called Touch ID.
See how it works, how secure it is and watch a hands-on video of it in action below:
Put your finger on the Home button, and just like that your iPhone unlocks. It’s a convenient and highly secure way to access your phone. Your fingerprint can also approve purchases from iTunes Store, the App Store, and the iBooks Store, so you don’t have to enter your password. And Touch ID is capable of 360-degree readability. Which means no matter what its orientation — portrait, landscape, or anything in between — your iPhone reads your fingerprint and knows who you are.
Senior Vice President of Hardware Engineering Dan Riccio stated that all information of your fingerprint is encrypted and stored within the new A7 chip within the iPhone itself. Your fingerprint information is NOT stored in Apple servers, NOT backed up with iCloud and NEVER available with other software. Your personal info is only accessible through the Touch ID home button.
The iPhone 5S uses an advanced capacitive touch sensor to read your fingerprint. Because of this, it is waaaayy more difficult to 'fool' or 'trick' compared with a more common optical fingerprint scanner by simply using a high-res photograph of a fingerprint. In order to fool a capacitive touch sensor such as the one in the 5S, one would have to make a 3-D mold of a fingerprint and engineer it so the mold would activate the capacitive sensor when touched... in other words not likely.
