What is Biometrics?
Biometrics is the science and technology of measuring and statistically analyzing biological data. When referring to Biometrics in information technology it is for measuring and analyzing human body characteristics such as fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements, especially for authenticating someone.
Types Of Biometrics:
- Hand Geometry: Very simple, measure hand/finger length, width.
- Fingerprints: 100% accurate, most widely used biometrics in the world.
- Iris Scan: Highly accurate, Relatively fast search.
- Voice Recognition: Used mostly for verification, easiest input.
- Facial Recognition: Very accurate, no physical contact, fast search, widely used today.
- DNA: 100% accurate, perfect for many applications.
Facial Scan Technology:
It a technology in which emphasizes those sections of the face which are less susceptible to alterations, including the upper outlines of the eye sockets, the areas surrounding one's cheekbones, and the sides of the mouth. Most technologies are resistant to moderate changes in hairstyle. The primary technologies are designed to locate a single face out of a database of thousands or hundreds of thousands, of faces.
Comparing the Primary Facial Scan Technologies:
There are four primary methods employed by facial scan vendors in which to identify and verify subjects. These methods include eigenfaces, feature analysis, neural network, and automatic face processing.
