Explanation

Biometric identification is a method used in computer science to identify and control access. It involves using unique and measurable characteristics to distinguish individuals. These characteristics are divided into two categories: physiological and behavioral. Physiological biometric identifiers include fingerprints, palm veins, facial recognition, DNA, palm prints, hand geometry, iris scanning, retinal scanning, and odor/scent. Behavioral identifiers consist of typing rhythm, gait, and voice.
