Facial recognition in Digital Age

Do you remember Hollywood movies Terminator: Rise of Machines or Ex Machina where facial recognition technologies are used in several ways? Today with digital technological advances, face recognition has become very important for businesses, to know who the customer is and send hyper-personalized offers to generate more revenues. Facebook has used facial recognition technology since 2011, to speed up the process of tagging friends or people in photos. When a user uploads an image to Facebook, the site's algorithms recognize the faces of friends and asks users if they would like to tag them. Security agencies were also early adopters of face recognition to identify suspicious behavior & threats to any big event or crowded areas like airports.
