● Public/Private Sector – Automated facial recognition is used to verify an individual against their stored face(s) or a small gallery of faces for access (e.g., smartphone, automated teller machine, frequent traveler, building access).
● Public Safety/Government – Automated facial recognition is used to search a biometric database and produce a computer-generated candidate list of facial images for further processing (e.g., identity/travel document issuance, processing, or verification, searching unknown faces to aid an investigation).
● Facial Assessment generally involves a superficial, often rapid, one-to-one comparison process of a facial image to a live subject for the purpose of identity verification (e.g., border crossing or police traffic stop).
● Facial Review involves a more complex comparison process conducted between an image and a subject or between sets of images.
● Facial Examination is the formal, systematic process (e.g., Analysis, Comparison, Evaluation - Verification [ACE-V]) by which two or more face images are compared. This may be an intensive process that can reach the level of a forensic analysis.
