Biometrics is a method of identifying people with unique physical characteristics, such as fingerprints, eyes or face.
Biometric devices identify a person by comparing the stored measurements (межементс) of individual physical characteristics with current measurements.
Identification based on biometric methods eliminates (еліменейтс) the need to remember the password.
The most common biometric devices are the fingerprint scanner, retina scanner ...
The fingerprint scanner makes a few snapshots of your finger and then each time checks for new shots with existing (екзистін) ones. If they match you will be given access to the system.
Retina / Iris scanner: Both are forms of biometric data capture based on different parts of the eye. In a retinal scan, a biometric template is formed by recording patterns of capillary blood vessels (веселс) at the back of the eye. Iris scanning can be performed remotely using a high-resolution camera and templates generated by a process similar to retinal scanning.
Facial Scanner: Facial recognition works by extracting key features such as relative position of eyes, nose, mouth, and ears from photographs of an individual's head or face.
Hand Geometry: Scanners generate templates based on various features of an individual's hand, including finger length.
Voiceprint: Voiceprint recognition compares vocal patterns of an individual with previously enrolled samples. An advantage of voice-printing techniques over other forms of biometric is the potential to detect duress or coercion through the analysis of stress patterns in the sample voiceprint.
