I am interested in developing an application that uses Touch ID sensor, to collect people fingerprint and use it as they have signed a document, or say they have received an UPS package, for example. So far, my search found the touch id sensor is to be used internally only by Apple built in apps and to unlock the phone. I could not get any official confirmation that I am not allowed to use the Touch ID sensor with my own application. Is it possible ?
With that in mind, I don't mean to access phone's security storage area or acess any fingerprint stored in the phone. I just want to get the fingerprint of a prove an event happened (like a person received a package) and keep that info inside my apps database.
