Facial recognition is a biometric verification category that relies on a “one to many” match. This form of biometric technology detects and locates the image of a face, captures and analyzes it, converts it to data, and compares it against a database of other known faces. Facial recognition has various law enforcement applications; police, for example, deploy facial recognition when seeking a match for a potential witness or suspect out of a crowd of people, or a sea of online photos.
