Which Face Unlocking Technology is used in Smartphones?Android Basic Facial Technology: Android operating system introduced face unlocking from its “Ice Cream Sandwich” version (Android 4.0) in 2011. The main drawback of this face unlocking technique was that it used to store only 2D images so that it was very easy for someone or thief to fool the system and unlock the phone easily. As this technique was not fully efficient so users used this option along with PIN or password. Surprisingly Google has discontinued the face unlock feature with Android 10 release due to security reasons.
Samsung Iris Technology: Iris scanner in Samsung device works based on the retina of eyes, just as human fingerprints are unique, the retina of the eye is also unique and no one can copy it. Samsung launched the Iris technology in its flagship devices Galaxy Tab Iris, Galaxy S7, and S7 Edge. Because earlier a normal front-facing camera could not scan the retina of the eye, Samsung gave a special infrared narrow focus camera to its flagship smartphone so that it could easily scan the retina of the eye. One disadvantage of the Iris technology is that it generally requires close proximity to camera, which can cause discomfort to eyes for some.
Face ID: Face ID is a type of facial recognition technology that the Apple company has designed and developed and started using in iPhone X, XS MAX, and iPad Pro (3rd & 4th Gen.) After introducing 3D facial recognition technology in 2017, Apple has continued using it in every new iPhones and iPads. With face ID introduction, Apple decided to discontinue the other biometric authentication, touch ID from 2017 in iPhones and iPads.
