I was thinking along the line of the government(who currently wants apple to add a back door) having a system where they could have someones fingerprint digitally, plugging in a computer and sending the finger print signal to the phone through the existing fingerprint scanner port. It is currently possible to make a fake fingerprint made
. but it takes a while and the system locks out after 24 hours. The government could make a system that would allow them to plug in their system, send the emulated signal. and unlock it quickly. I know this sound like paranoia, and its not something I would worry about, but it is something that Apple should worry about, and stay ahead of the curve.
