According to a May 2018 report, the FBI has had access to 412 million facial images for searches. And consider this: At least 117 million Americans have images of their faces in one or more police databases. Your facial signature - a mathematical formula - is compared to a database of known faces. The software identifies facial landmarks - one system identifies 68 of them - that are key to distinguishing your face. Key factors include the distance between your eyes and the distance from forehead to chin. Facial recognition software reads the geometry of your face. Your image may show you looking straight ahead or nearly in profile. Your face might appear alone or in a crowd. A picture of your face is captured from a photo or video.

Facial recognition can help verify a person’s identity, but it also raises privacy issues. It compares the information with a database of known faces to find a match. A facial recognition system uses biometrics to map facial features from a photograph or video. Facial recognition is a way of recognizing a human face through technology. ![]()
