With iOS 12 supporting multiple faces, is there any plan for the Security API to allow developers to discern if Face-A or Face-B was used to authenticate?
In general (expanding to TouchID), it would be nice to have a little more information on what biometric authentication events are occuring & top-level stats on the User's general biometric profile:
- Which fingerprint was used for an authentication event (e.g., simple pointer uuid linked to the fingerprint / face)?
- Which Face profile was used (same as above)?
- How *many* profiles (fingerprints or faces) are registered?
- Notifications events when profiles are added/removed
- Notification event for when User performs a biometric device unlock
If available, these additional (safe and unobtrusive!) details would enable developers to determine, with a high degree of authenticity, whether *the same* real-world person is interacting with our apps.
