What is biometrics definition ?
Biometric is made by two words bio and metric. Word bio mean “biographical profile of a person” and word metric mean “standard of measurement”. So if we will combine the word it will become a standard measurement of biographical profile of a person. The word biographical profile mean a person face, iris, voice, hand, fingerprint and dna.
What is the use of biometrics ?
Biometric use is to identify the person by his/her biographical signature.
Types of biometrics
Biometrics has two major categories physiological and behavioral. We can measure biometrics by these two categories to identify the person.
Physiological
Iris Recognition
Iris recognition biometric use one or both the irises complex and stable mathematical pattern to identify his/her identification. This can only be identify by some distance. We can scan the iris pattern from the camera.
Retina Recognition
Retina scanning send a beam of light in your eyes to find the pattern. Retina scan required a very close distance from your eyes to capture your retina image.
Face Recognition
Face recognition compare 80 nodal points on a human face. Nodal points are end points used to measure variables on a person’s face. which includes the length and width of the cheekbone, nose, eye socket depth and the shape of your face.
Fingerprint Recognition
Fingerprint recognition take picture of fingers and recognize it’s arches, whorls, and loops along with the outlines of edges.
DNA Recognition
Iris recognition biometric use one or both the irises complex and stable mathematical pattern to identify his/her identification. This can only be identify by some distance. We can scan the iris pattern from the camera.
Hand Geometry Recognition
Retina scanning send a beam of light in your eyes to find the pattern. Retina scan required a very close distance from your eyes to capture your retina image.
Behavioral
Signature Recognition
Iris recognition biometric use one or both the irises complex and stable mathematical pattern to identify his/her identification. This can only be identify by some distance. We can scan the iris pattern from the camera.
Keystroke Recognition
Retina scanning send a beam of light in your eyes to find the pattern. Retina scan required a very close distance from your eyes to capture your retina image.
Voice Recognition
Iris recognition biometric use one or both the irises complex and stable mathematical pattern to identify his/her identification. This can only be identify by some distance. We can scan the iris pattern from the camera.
