More about Touch ID technology in iPhone 5S
Around innovative fingerprint recognition technology called Touch ID with more questions than answers. The latest probe appeared in the iPhone 5S and was developed by the Israeli company AuthenTec, which Apple bought last year. Simply scan a finger applied to a button Home, allows you to unlock your phone and log when purchasing content from the iTunes Store , App Store, or iBookstore. But what happens next?
Neither the online Apple, nor in the promotional video does not tell about the technical details related to the operation Touch ID. Apparently to allay the legitimate concerns of users about maintaining the confidentiality of data, the company decided to delegate a representative of his press service, who spoke in detail about the technology in an interview with Wall Street Journal:
“The new iPhone 5S from Apple, is equipped with a fingerprint reader does not store fingerprint images at the user’s device. Instead, the new Touch ID system only stores the data on the prints, which are encrypted within the processor iPhone »
After the saved profile of your fingerprint is compared with the sensor to authenticate the user. Even if anyone is able to crack the chip (which is virtually impossible), the attacker can not simply recreating the fingerprint pattern the user to access the phone.
In addition, an Apple representative told about another feature designed to improve safety. As a backup option for users to make us familiar password. Only the password (not the finger scan) can unlock the phone if it crashes or is not enabled for 48 hours. This will give hackers a minimum stock of time trying to somehow develop a solution to bypass the procedure of verification of biometric data. Of course, the settings can be switched on and off Touch ID, however, the mandatory reserve entering the password, we hear for the first time.
Another feature: although the Touch ID technology is more advanced than the thermal fingerprint scanners found on some notebook models, Apple claims that the system can not work if you have too sweaty fingers. Mandatory password entry also can be useful if the scanner can not read your “fingers” due to perspiration. If one of your fingers from injury suffered or been under the surgeon’s scalpel, Apple says that for a successful unlock the iPhone, you can take advantage of surviving fingers.
As mentioned above, the user’s biometric data is stored in a special secure unit of the new A7 processor. Only Touch ID chip allowed to access this module. In addition, Apple says that the results of the scan are stored locally and are not downloaded to cloud services. In other words, prone to delusions of persecution of people who had heard about the stories from the PRISM program , can sleep peacefully.
“These data will never be stored on Apple’s servers and downloaded to iCloud, – said in a press release from Apple. – All the information about the fingerprint is stored securely in an isolated area inside the processor A7 new iPhone 5S »
The location of said separate zones can be seen in the illustration below:
Vice president of Apple’s hardware design Dan Riccio says that “the sensor uses capacitive touch technology to obtain images of your fingerprints in high definition.”
Finally tell you about one particular that caused mixed reactions from users and some confusion among developers. Apple has decided not to provide third-party developers API, related to the operation of the scanner Touch ID. Although it is impossible for us to use the system as efficiently as possible, it is further proof of Apple desire to best protect your personal information, so that they do not fall into the wrong hands. Therefore, if the Touch ID and will continue to develop and improve, it is likely that it will happen within the ‘walled garden »Apple: for example, for logging into websites through the browser Safari.Viewing:-127
