Discussion
This property returns a value only when the can
method succeeds for a biometric policy or the evaluate
method is called and a successful biometric authentication is performed. Otherwise, nil
is returned.
The returned data is an opaque structure. It can be used to compare with other values returned by this property to determine whether the authorized database has been updated. However, the nature of the change cannot be determined from this data.
