- Gait patterns
- Voice dynamics
- Mouse or touchscreen usage
Behavioral biometrics offer an additional layer of security through continuous monitoring, providing ongoing protection as the user remains logged in.
The Most Common Biometric Authentication Technologies
Building upon these categories, several popular biometric methods have emerged to play significant roles in today's real-world applications:
- Fingerprint Recognition: Capitalizing on the unique ridges found on fingertips, fingerprint recognition is one of the most widely used and reliable forms of biometric authentication.
- Iris Recognition: Iris scanning maps the intricate patterns within the colored ring surrounding the pupil, providing highly accurate identification. Newer devices, such as the Apple Vision Pro and select Samsung models, have already integrated iris scanning technology.
- Retinal Scanning: Retinal scanning analyzes patterns of blood vessels found at the back of the eye, offering unmatched stability and accuracy. Retinal scanners employ specialized low-intensity light sources to obtain these vascular patterns securely.
- Facial Recognition: Facial recognition audio technology measures and assesses distances and proportions of facial features, including the eyes, nose, cheekbones, and jawline. Popular in smartphones from brands like Apple and Samsung, facial recognition simplifies the authentication process while ensuring secure logins.
- Hand Geometry: Assessing the physical dimensions of the hand, such as finger lengths, widths, and palm size, hand geometry offers a less unique yet still useful method of identification in controlled environments like offices or manufacturing facilities.
