How does this involve voting? The Authentec chip (Authentec is now owned by Apple) stores portions of the fingerprint (you do NOT need to roll your fingerprint onto the screen. You touch the button several times (this registers a 360 degree rotation of how you touch the home button) with several fingers. Those fingers don't even have to belong to you (spouse can put a finger or two). I don't know how many fingerprints can be logged onto the account. The fingerprint is stored in the A7 chip - where it is used to identify YOU to the phone. That's it. Your fingerprint never leaves the phone - it was designed and built with security in mind. The iPhone simply says "You are YOU - I know this by your fingerprint or by your passcode". If someone steals your phone - the iPhone will now that who ever is attempting to use the phone is not a legitimate user. Because they are illegitimate, there are some things they are NOT allowed to do. Like, reset the phone.
Thats what apple says, anyway. And we all know you can trust the govt and large corporations. You cannot access the iOS operating systen to find out
I was joking, but trust me, the dems would pull out the stops to somehow use this tech to make dem votes.
During the Zimmerman trial, the prosecution argued that certain of Trayvon's texts were inadmissible, because it could not be proved that Trayvon sent them, as opposed to someone having access to his phone.
If your phone unlocks by fingerprint, and the phone maintains a log of access and whether it was by fingerprint or passcode, then a prosecutor could successfully argue that you, beyond shadow of doubt, were the person on the phone when a call/text/pic was made, as opposed to some other person working your phone without your knowledge.
