Biometric technologies

Fingerprints

which check the unique patterns of ridges and valleys on your fingertips using either optical, ultrasonic, or capacitive scanners

Retina

scanning uses the unique patterns of blood vessels in the retina to tell users apart

Iris recognition

systems use pattern recognition and infrared imaging to uniquely identify an individual’s eyes. _____ can be accomplished from farther away than retina scans, making it preferable in many circumstances

Facial recognition

techniques match specific features to an original image in a database. ____ is widely used in Apple iPhone for Face ID, making it a broadly deployed biometric technology

Voice recognition

systems rely on patterns, rhythms, and the sounds of a user’s voice itself to recognize the user

Vein recognition

sometimes called vein matching or vascular technology, uses scanners that can see the pattern of veins, often in a user’s finger or arm. Vein scanners do not need to touch the user, unlike fingerprint scanners, making them less likely to be influenced by things like dirt or skin conditions

Gait analysis

measures how a person walks to identify them
