what is biometric

Biometrics are biological measurements or physical characteristics that can be used to identify individuals. Biometric authentication is used in computer science as a form of identification and access control. Biometric identifiers are the distinctive, measurable characteristics used to label and describe individuals. They are often categorized as physiological characteristics, which are related to the shape of the body, or behavioral characteristics, which are related to the pattern of behavior of a person. Examples of physiological characteristics include fingerprint, palm veins, face recognition, DNA, palm print, hand geometry, iris recognition, retina, odor/scent, voice, shape of ears, and gait. Examples of behavioral characteristics include mouse movement, typing rhythm, gait, signature, behavioral profiling, and voice. Biometrics are used in various fields, including computer science, cybersecurity, healthcare, and law enforcement.
