Biometrics comes from the Greek words Bios, which means Life, and metron, which means measure.
With biometric security you can measure physical characteristics of a person and without much of an effort. One example of an noncomplex biometrical identifier is the driving license. It contains data about your height, hair color, eye color and ears. These data is not secure data since you can easily change your hair color and eye color with another contact lens. Even your height changes along the time. Another example of a noncomplex biometrical security identification is the signature, which can easily be changed although it still gives us an easy identification process and it is very common today.
There are though biometric data that does not change. Biometric security processes have several demands that should be well-reached or at least partly reached to be successful in business. Here are a couple of demands:
- The physical characteristics shall not change over the course of the person’s lifetime.
- The physical characteristics must individually and uniquely identify the person.
- The physical characteristics got to be easily scanned or read; hopefully with inexpensive equipment, and give an immediate result.
- The data should easily be checked on the person and it’s willing (or knowing) should not determine the outcome.
Another good thing to have is legacy data such as Face recognition and voice recognition.
Here are a couple of working biometrical security identifiers:
Fingerprint recognition:
By the fourth month of fetal development you have your fingerprints. Once they are formed, the fingers will get larger, but the relationship between the ridges will stay the same which means that you can use your old fingerprints your whole life.
Iris scan:
An iris scan will analyze your rings, furrows and freckles in the colored ring surrounding the pupil of the eye. More than 200 points can be used to measure your Iris, which will give absolute results.
Face recognition:
Your facial characteristics are now compared using the size, shape and relationship in your face. This method has always been used for humans to remember faces and give authority because of recognition.
Voice recognition
This will analyze your tone, pitch, cadence and frequency of a person’s voice.
