The color of your eyes. The slope of your nose. The shape of your lips.

These are all elements that make you, you. These unique qualities of your face are also what facial recognition technology uses to pick you out of a crowd.

While facial recognition was once something only seen in Sci-Fi movies, it is now a part of our daily lives. And whether we like it or not, it's here to stay.

While Hollywood loves including facial recognition as a plot-point in media, movies and television haven't done a great job explaining how facial recognition software actually works.

Facial recognition uses a combination of biometrics software applications, artificial intelligence, 3D mapping, and deep learning to compare and analyze patterns based on someone's face. Although it's mostly used for security and surveillance purposes, there is increasing interest across various markets, as well as use for the everyday consumer, especially as it gets more secure, advanced, and reliable.
