Touch ID: the Security Design of iPhone 5S

    As expected, Apple has successfully taken the wraps off of its latest flagship smart phone- iPhone 5s at its headquarters in Cupertino, Calif on Tuesday. Though, it is outwardly similar to the previous-generation iPhone 5, it also has a number of key upgrades which are represented by Touch ID, A7 chip with 64-bit architecture, iSight camera and LTE wireless. Among these breakthroughs, I think the Touch ID impresses me most.

Touch ID is an integrated fingerprint identity sensor in the home button, which scans the fingertip of the person pressing the button and unlocks the phone. This feature can also eliminate the need for entering your Apple ID password every time you download a new app. The fingerprint sensor, which has a protective layer of durable sapphire crystal and a stainless steel detection ring around, can store multiple fingerprints and read them in any orientation, so you can share your phone with specific family members without having to reveal your pass code.

Since there are no fingerprints are exactly alike,by adopting this technology, it is much harder for thieves to crack the new fingerprint identifier than the traditional password. What’s more, users’ fingerprints data will be stored in the phone instead of the Apple server, which largely reduces the risk of being stolen through the Internet.
