This topic answers frequently asked questions about financial-grade face detection.
In the app authentication solution, why is a server-side query required if the mobile client already returned a result?
Results from the mobile client may not be accurate. Rely on the server-side query for the definitive result. For more information, see Query authentication results on a mobile client. If authentication fails, query the server to find the specific reason for the failure.
What is the source of the comparison data?
Face verification is performed against an authoritative public security database.
