I am trying to make an app similar to the way you can set a password upon unlocking an iphone. I have access to face-recognition tech, and I want to make it so that when you slide to unlock you don't have immediate access to the homescreen. Instead, you"re asked to take a picture of your face, and if it matches then the homescreen unlocks. I'm aware that any app that changes the slide to unlock or the homescreen features will be rejected, but this one will just present another layer after the slide to unlock. Is there a way to do this?
Thanks a lot!
