While Samsung Electronics broadened the horizon of smart phone biometric technology that was limited to fingerprints by loading smartphones with the world’s first iris recognition function, Apple came up with its 3D face recognition technology. LG Electronics enhanced convenience with voice recognition which unlocks smartphones with voices.
Apple took the wrap off the iPhone X in honor of the 10th anniversary of the iPhone, at Steve Jobs Theater in Apple Park, its new office building in Cupertino, California of the US. The iPhone X features a new face identification function, Face ID, instead of Touch ID which recognizes fingerprints. Touch ID which was first introduced through the iPhone 5S in 2013, disappeared from the iPhone X.
Face ID is to use a user’s face as a password and is powered by a front infrared camera. Face ID projects more than 30,000 invisible dots to create a precise depth map of your face. Machine learning is applied to Face ID so the iPhone X recognize you even when you wear glasses, a hat, grow beards or changes your hairstyle. Face ID can recognize you in a dark environment.
Face ID unlocks your iPhone X only when you look toward the device with your eyes open. Your photos do not work.
Face recognition is nothing new. This technology came out decades ago. Samsung Electronics also loaded the Galaxy S8 with a face recognition function that uses deep learning. The technology tells your face from others’. The more face recognition is used, the more the amount of learning increases, enhancing accuracy. Face recognition can distinguish the face of its users even if an angle of the face does not match a face angle registered first.
However, Samsung recommends iris recognition or fingerprint recognition for the perfect level of security. Apple also made it possible to use the iPhone X’s Face ID for Apple Pay among others and Face ID offers complete security.
Currently, iris recognition and fingerprint recognition are considered the most secure and convenient biometrics-based authentication applied to smartphones. Iris recognition was first introduced by Samsung Electronics last year through the Galaxy Note 7 and was applied to premium smartphones such as the Galaxy S8 and the Galaxy Note 8 in succession.
The iris is a tissue located around the pupil and is formed when a person is young and its shape does not change through a person’s lifetime. Even twins have different iris information. Samsung's iris recognition is convenient because it is a non-contact type that saves users toughing devices. The iris is recognized by a front infrared camera, so iris recognition is not affected by surrounding environments.
LG Electronics loaded the V30, a strategic smartphone to be launched on September 21 with voice recognition function. This is based on a comprehensive analysis of a user's voice waveform, unique pronunciation, pitches, accents, and speaking speed. However, it is recommended to use fingerprints, patterns, and passwords for functions that require complete security because others can unlock the phone by secretly recording the user's voice or imitating it.
