What is the most common biometrics?
The most common biometrics is the given below:
Face geometry (Photo): In this the computer takes the picture of your face and matches this with a prestored picture.
Fingerprints (Finger scan): When a user needs access, matching fingerprint against a template having authorized person’s fingerprints.
Hand Geometry: As fingerprints except the verifier utilizes a TV like camera to capture the picture of the user’s hand.
Blood vessel pattern within the retina of a person’s eye: A match is completed between the pattern of the blood vessels into retina which is being scanned and prestored picture of retina.
Voice (Voice Print): In this a match between user’s voice and voice pattern stored onto templates. Signature: It is matched against the prestored authentication signature.
Keystike Dynamics: The match of person’s keyboard pressure and speed against prestored information.
Others: As Thermograph, by using a PIN and iris scan.
