FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A biometric device is a security identification and authentication device. Such devices use automated methods of verifying or recognising the identity of a living person based on a physiological or behavioral characteristic. These characteristics include fingerprints, facial images, iris and voice recognition.

Detailed explanation-2: -They are electrical devices used for biometric verification, identification and authentication. They could be used to identify people based on their unique physical features such as fingerprints, iris scans, facial traits, and so on.

Detailed explanation-3: -Input Devices : Biometric Devices. A biometric input device measures a unique physical chracteristic of a person. The most common biometric devices are used to input a person’s fingerprint into a computer. More sophisticated devices use a camera to input a description of a person’s iris (the coloured part of the eye).

Detailed explanation-4: -Face, fingerprint, hand geometry, palm print, iris, voice, signature, gait, and keystroke dynamics are examples of biometric traits. In the context of a given system and application, the presentation of a user’s biometric feature involves both biological and behavioral aspects.

Detailed explanation-5: -What is Biometric Authentication? Authentication is a way to verify, beyond a doubt, that a person is who they say they are. Biometric authentication performs this verification by checking distinctive biological or behavioral characteristics.
