That Touch ID used great security to store our fingerprints and data is not new. What happens is that when storing this data on the A7 chip makes home button replacement impossible maintaining the functionality of the biometric sensor.
The find occurred when a customer sent to mendmyi your iPhone 5s for a color treatment. This treatment consists of changing the aluminum parts, including the main chassis of the phone, for other colored ones. When the customer got their phone back, they found out that Touch ID was not working.
In order to try to fix the problem, many alternatives were tried; change the Touch ID sensor to verify its operation, replace the Touch ID dock connector with which it makes contact, and even replace the logic board itself. Nothing worked.
Going back in the process, they reinstalled the original button and Touch ID started working again. After extensive research, they discovered that actually the button cable that connects it to the motherboard, does so to an individual part of the A7 chip.
I do not think this procedure is designed to prevent you from making cheaper replacements if you have an incident, it is more accurate to say that it is a way to increase and surround the protection that our footprints have. Apple has already explained to us that our fingerprints They are not accessible to iOS applications, and they are never stored on your servers or in the iCloud backup, so it is not easy to hack them. If we add that each Touch ID sensor is linked to its attached tab of the A7 chip, we rule out the possibility that the hacked home buttons could intercept the communications between the two ends of the system.
Apple has really gone to great lengths to make a biometric system, using Touch ID, safe and reliable. For users, this means that it is almost impossible to access the fingerprints stored on your iPhone.

Remember that the system used by the iPhone 5S is like the ones used by the military. Only they included the original functions to access the main screen of the iOS and exit the applications, in addition to all the original functions of the home button that it already had. But without a doubt this information that you bring confirms that it does indeed have a direct connection with the A7. Unlike all previous iPhones.
MMM good to read ...
Pretty good. Well, it was no wonder since they always give us quality, of course for a high price but it is part of the service that is not seen
