Android app that demonstrates the use of Ver-ID to unlock a screen without showing the camera preview.
This demo addresses the use case for unlocking an app for a user based on a single registered face, without going through any liveness detection, or showing the user their face at all. With the demo apk, the first step is to register a face - then after clicking "unlock" it goes into a mode where it is looking for the registered face and when authenticated the icon changes to "unlocked." A suggested implementation would be to have a "Start" button on the screen for the user, and clicking that would invoke the "unlock" mode, and when a face is found and authenticated, the app would proceed into a secure task or data collection phase.
Note that this is provided as a quick demonstration of the use case where an authentication session does not provide a camera preview for the user - it simply happens in the background. In a real app you may want to provide more user feedback if the face is not found etc.
